Orwa SA, Gudnadottir U, Boven A, Pauwels I, Versporten A, Vlieghe E, Brusselaers N. Global prevalence of antibiotic consumption during pregnancy: A systematic review and meta-analysis. J Infect 2024; 89:106189. [PMID: 38844084 DOI: 10.1016/j.jinf.2024.106189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2024] [Revised: 05/22/2024] [Accepted: 05/27/2024] [Indexed: 06/14/2024]
Abstract
BACKGROUND Antibiotic use during pregnancy is widespread with notable variations across regions. METHODS This systematic review and meta-analysis (Prospero protocol CRD42023418979) examines the prevalence and variability of antibiotic use in pregnancy globally and regionally, considering different methodologies and maternal characteristics. We searched Embase, PubMed, and Web of Science for observational studies published in English from the year 2000 and onwards. Random-effect meta-analyses were used to pool the prevalence of antibiotic consumption during pregnancy, presented as percentages with 95% confidence intervals (CI). Joanna Briggs Institute Critical appraisal checklist for prevalence studies was used for bias assessment. FINDINGS Overall, 116 studies (14 from Africa, 24 from the Americas, six from Eastern Mediterranean, 57 from Europe, four from South-East Asia and 11 from Western Pacific) were included (33,821,194 pregnancies). The majority of studies (84.5%) were appraised with a low risk of bias. The prevalence of antibiotic consumption during pregnancy ranged between 0.04 to 90%, with a pooled estimate of 23.6% (95% CI: 20.1-27.5, I2 =100%). Low-income countries had the highest pooled prevalence (45.3%, 95% CI: 15.4-79.1, I2 =99.6%). Regionally, the Western Pacific had the highest pooled prevalence (34.4%, 95% CI: 13.4-64.1, I2 =100%). The prevalence of antibiotic consumption during pregnancy increased over time in the Americas and Western Pacific. The studies exhibited considerable heterogeneity (I2 >95%), and the trim-and-fill method estimated a potential 10% underestimation of the overall pooled prevalence, suggesting publication bias. INTERPRETATION This meta-analysis suggests that about 1/4 of women worldwide use antibiotics during pregnancy. This study suggests a high prevalence of antibiotic consumption during pregnancy with disparities according to region and level of country income, ethnicity and whether antibiotics were prescribed or self-medicated. There was a variability in reported findings across age categories, potential bias from small sample sizes, and language bias from including only studies published in English.

Thunbo MØ, Vendelbo JH, Witte DR, Larsen A, Pedersen LH. Use of medication in pregnancy on the rise: Study on 1.4 million Danish pregnancies from 1998 to 2018. Acta Obstet Gynecol Scand 2024; 103:1210-1223. [PMID: 38491733 PMCID: PMC11103131 DOI: 10.1111/aogs.14805] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 01/02/2024] [Accepted: 01/30/2024] [Indexed: 03/18/2024]
Abstract
INTRODUCTION Maternal demographics have evolved, and more women than ever enter pregnancy with preexisting comorbidity and with potentially complex medication exposure, including polypharmacy (concomitant intake of multiple medications). This study aims to describe the evolution of medication use in pregnancy in Denmark from 1998 to 2018 with special focus on polypharmacy, patterns of use, and underlying demographics. MATERIAL AND METHODS A Danish nationwide historical registry study based on all clinically recognized pregnancies with a gestation ≥10 weeks between 1998 and 2018. Medication use was estimated by redemption of prescriptions during pregnancy. RESULTS Among a total of 1 402 327 clinically recognized pregnancies, redemption of at least one prescription medication during pregnancy increased from 56.9% in 1998 to 63.3% in 2018, coinciding with an increased use of polypharmacy (from 24.8% in 1998 to 35.2% in 2018). The prevalence of pregnant women who used medications for chronic conditions increased more than the prevalence of women treated for occasional or short-time conditions. Redemption of one or multiple prescription medications during pregnancy was mostly seen among pregnant women ≥35 years of age. However, pregnant women <25 years old exhibited the largest increase in medication use during the study period. CONCLUSIONS Medication use in general, and polypharmacy in particular, increased from 1998 to 2008, possibly as the result of an increased prevalence of pregnant women with chronic conditions requiring pharmacological treatment. Notably, a marked maternal age-based discrepancy in usage pattern was observed, highlighting the need for further research in this area. The rise in the prevalence of polypharmacy during pregnancy underscores the need for pharmacovigilance to monitor adverse effects. Future studies should investigate the patterns of polypharmacy and the accompanying maternal and fetal risks.

Prenatal exposure to antiseizure medications and fetal growth: a population-based cohort study from the Nordic countries. THE LANCET REGIONAL HEALTH. EUROPE 2024; 38:100849. [PMID: 38476755 PMCID: PMC10928302 DOI: 10.1016/j.lanepe.2024.100849] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 01/07/2024] [Accepted: 01/12/2024] [Indexed: 03/14/2024]
Abstract
Background The short- and long-term consequences of restricted fetal growth cause considerable concern, and how prenatal exposure to different antiseizure medications (ASMs) affects fetal growth remains uncertain. Methods This was a population-based cohort study of liveborn singleton children born in Denmark, Finland, Iceland, Norway, and Sweden from 1996 to 2017. Prenatal exposure was defined as maternal filling of prescriptions for ASM during pregnancy registered in national prescription registries and primary outcomes were adjusted odds ratios (aORs) of microcephaly or being born small for gestational age. Findings We identified 4,494,918 children (males: 51.3%, 2,306,991/4,494,918), including 38,714 (0.9%) children of mothers with epilepsy. In the overall population, prenatal monotherapy exposure with carbamazepine (aOR: 1.25 (95% CI: 1.12-1.40)), pregabalin (aOR: 1.16 (95% CI: 1.02-1.31)), oxcarbazepine (aOR: 1.48 (95% CI: 1.28-1.71)), clonazepam (aOR: 1.27 (95% CI: 1.10-1.48)), and topiramate (aOR: 1.48 (95% CI: 1.18-1.85)) was associated with risk of being born small for gestational age, and carbamazepine was associated with microcephaly (aOR: 1.43 (95% CI: 1.17-1.75)). In children of mothers with epilepsy, prenatal exposure to carbamazepine (aOR: 1.27 (95% CI: 1.11-1.47)), oxcarbazepine (aOR: 1.42 (95% CI: 1.18-1.70)), clonazepam (aOR: 1.40 (95% CI: 1.03-1.89)), and topiramate (aOR: 1.86 (95% CI: 1.36-2.54)) was associated with being born small for gestational age; carbamazepine, with microcephaly (aOR: 1.51 (95% CI: 1.17-1.95)). No associations with small for gestational age and microcephaly were identified after prenatal exposure to lamotrigine, valproate, gabapentin, levetiracetam, phenobarbital, acetazolamide, phenytoin, clobazam, primidone, zonisamide, vigabatrin, ethosuximide and lacosamide, but except for lamotrigine, valproate, gabapentin, and levetiracetam, numbers of exposed children were small. Interpretation Prenatal exposure to carbamazepine, oxcarbazepine, clonazepam, and topiramate was associated with increased risk of being born small for gestational age in both the overall population and in children of women with epilepsy suggesting that prenatal exposure to these drugs is associated with fetal growth restriction.

Patterns of Prescription Medication Use during the First Trimester of Pregnancy in the United States, 1997-2018. Clin Pharmacol Ther 2023; 114:836-844.

Abstract
The objective of this analysis was to describe patterns of prescription medication use during pregnancy, including secular trends, with consideration of indication, and distributions of use within demographic subgroups. We conducted a descriptive secondary analysis using data from 9,755 women whose infants served as controls in two large United States case-control studies from 1997-2011 and 2014-2018. After excluding vitamin, herbal, mineral, vaccine, i.v. fluid, and topical products and over-the-counter medications, the proportion of women that reported taking at least one prescription medication in the first trimester increased over the study years, from 37% to 50% of women. The corresponding proportions increased with increasing maternal age and years of education, were highest for non-Hispanic White women (47%) and lowest for Hispanic women (24%). The most common indication for first trimester use of a medication was infection (12-15%). Increases were observed across the years for medications used for indications related to nausea/vomiting, depression/anxiety, infertility, thyroid disease, diabetes, and epilepsy. The largest relative increase in use among women was observed for medications to treat nausea/vomiting, which increased from 3.8% in the earliest years of the study (1997-2001) to 14.8% in 2014-2018, driven in large part by ondansetron use. Prescription medication use in the first trimester of pregnancy is common and increasing. Many medical conditions require treatments among pregnant women, often involving pharmacotherapy, which necessitates consideration of the risk and safety profiles for both mother and fetus.

Abstract
Background The use of medication during pregnancy is a complex issue that requires careful consideration to avoid potential harm to the developing fetus. Despite the existence of guidelines and restrictions on medication use during pregnancy, pregnant women in Nigeria often have limited access to information regarding drug use and may rely on their own judgment or the advice of non-professionals when making decisions about medication use. Objectives To assess Nigerian pregnant women's knowledge, attitude, and practice toward the use of drugs and restriction/contraindications in pregnancy. Methods A descriptive cross-sectional study was conducted among pregnant women who visited the Federal Medical Center, Umuahia, from January to February 2023. A self-administered questionnaire was answered by conveniently sampled participants. Data were collected about their sociodemographic characteristics, knowledge, attitude, and practice. Descriptive statistics and inferential statistics utilizing the Pearson's chi-Square test were used for data analysis. The level of significance was set at p < 0.05. Results One hundred and fifty-two pregnant women completed the questionnaire (60.8% response rate) and were mostly married (n = 148; 95.0%). Majority were between the age of 25 to 35 years (n = 107; 70.4%), had a university/bachelor's degree (n = 94; 61.8%), and were business women (n = 85; 56.0%). About 35.5% of the respondents had good knowledge of medication restrictions in pregnancy. The majority of the respondents had a positive attitude (n = 98; 64.5%) and good practice (n = 139; 91.4%). Conclusion The findings established that a substantial proportion of the women had a positive attitude and good practice of medication use and restrictions in pregnancy. However, the level of knowledge was surprisingly poor among the study group. There is a need to educate pregnant women on safe medication use and avoidance during pregnancy.

Abstract
PURPOSE OF REVIEW We review the literature and discuss the logistics of testing pregnant patients for penicillin allergy. RECENT FINDINGS As in the general population, pregnant patients commonly report a penicillin allergy, but most patients are able to tolerate penicillin. Avoidance of beta-lactams in pregnancy is associated with increased morbidity: longer hospitalizations, more frequent infections, and more complications. Penicillin allergy testing is safe in pregnant patients, and obstetricians are eager for allergists to offer this procedure to their patients. As allergists, we can improve our patients' health outcomes by offering penicillin allergy testing in our practices. The protocols for testing both with and without skin testing in pregnant patients have been studied, and future studies will continue to clarify the safety and efficacy of penicillin allergy delabeling in pregnant patients.

Abstract
BACKGROUND The number of medications prescribed during pregnancy has increased over the past few decades. Few studies have described the prevalence of multiple medication use among pregnant women. This study aims to describe the overall prevalence over the last two decades among all pregnant women and those with multimorbidity and to identify risk factors for polypharmacy in pregnancy. METHODS A retrospective cohort study was conducted between 2000 and 2019 using the Clinical Practice Research Datalink (CPRD) pregnancy register. Prescription records for 577 medication categories were obtained. Prevalence estimates for polypharmacy (ranging from 2+ to 11+ medications) were presented along with the medications commonly prescribed individually and in pairs during the first trimester and the entire pregnancy period. Logistic regression models were performed to identify risk factors for polypharmacy. RESULTS During the first trimester (812,354 pregnancies), the prevalence of polypharmacy ranged from 24.6% (2+ medications) to 0.1% (11+ medications). During the entire pregnancy period (774,247 pregnancies), the prevalence ranged from 58.7 to 1.4%. Broad-spectrum penicillin (6.6%), compound analgesics (4.5%) and treatment of candidiasis (4.3%) were commonly prescribed. Pairs of medication prescribed to manage different long-term conditions commonly included selective beta 2 agonists or selective serotonin re-uptake inhibitors (SSRIs). Risk factors for being prescribed 2+ medications during the first trimester of pregnancy include being overweight or obese [aOR: 1.16 (1.14-1.18) and 1.55 (1.53-1.57)], belonging to an ethnic minority group [aOR: 2.40 (2.33-2.47), 1.71 (1.65-1.76), 1.41 (1.35-1.47) and 1.39 (1.30-1.49) among women from South Asian, Black, other and mixed ethnicities compared to white women] and smoking or previously smoking [aOR: 1.19 (1.18-1.20) and 1.05 (1.03-1.06)]. Higher and lower age, higher gravidity, increasing number of comorbidities and increasing level of deprivation were also associated with increased odds of polypharmacy. CONCLUSIONS The prevalence of polypharmacy during pregnancy has increased over the past two decades and is particularly high in younger and older women; women with high BMI, smokers and ex-smokers; and women with multimorbidity, higher gravidity and higher levels of deprivation. Well-conducted pharmaco-epidemiological research is needed to understand the effects of multiple medication use on the developing foetus.

Abstract
Background Non-communicable diseases [NCDs] are leading causes of ill health among women of reproductive age and an increasingly important cause of maternal morbidity and mortality worldwide. Reliable data on NCDs is necessary for accurate measurement and response. However, inconsistent definitions of NCDs make reliable data collection challenging. We aimed to map the current global literature to understand how NCDs are defined, operationalized and discussed during pregnancy, childbirth and the postnatal period. Methods For this scoping review, we conducted a comprehensive global literature search for NCDs and maternal health covering the years 2000 to 2020 in eleven electronic databases, five regional WHO databases and an exhaustive grey literature search without language restrictions. We used a charting approach to synthesize and interpret the data. Results Only seven of the 172 included sources defined NCDs. NCDs are often defined as chronic but with varying temporality. There is a broad spectrum of conditions that is included under NCDs including pregnancy-specific conditions and infectious diseases. The most commonly included conditions are hypertension, diabetes, epilepsy, asthma, mental health conditions and malignancy. Most publications are from academic institutions in high-income countries [HICs] and focus on the pre-conception period and pregnancy. Publications from HICs discuss NCDs in the context of pre-conception care, medications, contraception, health disparities and quality of care. In contrast, publications focused on low- and middle-income countries discuss NCDs in the context of NCD prevention. They take a life cycle approach and advocate for integration of NCD and maternal health services. Conclusion Standardising the definition and improving the articulation of care for NCDs in the maternal health setting would help to improve data collection and facilitate monitoring. It would inform the development of improved care for NCDs at the intersection with maternal health as well as through a woman's life course. Such an approach could lead to significant policy and programmatic changes with the potential corresponding impact on resource allocation.

Paediatr Perinat Epidemiol 2021; 35:450-458. [PMID: 33438777 DOI: 10.1111/ppe.12740] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2020] [Revised: 10/04/2020] [Accepted: 10/25/2020] [Indexed: 01/11/2023]
Abstract
BACKGROUND Risk factors for congenital limb deficiencies are poorly understood. OBJECTIVE To investigate risk factors for congenital limb deficiencies. METHODS We conducted a nationwide population-based case-control (1:5) study in Finland, using national registers on congenital anomalies, births, and induced abortions, cross-linked with data on maternal prescription medicine use obtained from the registers on Reimbursed Drug Purchases and Medical Special Reimbursements. Five hundred and four children with limb deficiencies (241 isolated, 181 syndromic, and 82 other associated anomalies) were identified, and 2,520 controls were matched to cases on residence and year of pregnancy. Non-syndromic cases (n = 323) were subdivided into longitudinal (n = 120), transverse (n = 123), intercalary (n = 24), mixed (n = 18), and unknown (n = 38) deficiencies. RESULTS Pregestational diabetes was associated with all limb deficiencies (adjusted odds ratio [OR] 12.71, 95% confidence interval [CI] 2.37, 68.25) and with isolated (OR 11.42, 95% CI 2.00, 64.60) deficiencies. Primiparity was associated with increased risk of congenital limb deficiencies among all cases (OR 1.49, 95% CI 1.15, 1.93), isolated cases (OR 1.46, 95% CI 1.09, 1.96), and among cases with longitudinal (OR 1.90, 95% CI 1.24, 2.90) and transverse deficiencies (OR 1.75, 95% CI 1.13, 2.70). Young maternal age (<25 years) was associated with all congenital limb deficiencies (OR 1.40, 95% CI 1.02, 1.90) and transverse deficiencies (OR 1.76, 95% CI 1.05, 2.96). Advanced maternal age (≥35 years) was associated with syndromic (OR 1.82, 95% CI 1.19, 2.78) and transverse deficiencies (OR 1.94, 95% CI 1.06, 3.57). Maternal antiepileptic medication was associated with all (OR 5.77, 95% CI 1.75, 19.04) and with isolated cases (OR 3.83, 95% CI 1.02, 14.34). CONCLUSIONS It is important that pregnant women taking medications, especially antiepileptics, or women with pregestational diabetes are carefully monitored with regard to the occurrence and risk of limb deficiencies in the fetus.

Abstract
Purpose
To study if second-generation antipsychotic (S-GA) use during the first trimester of pregnancy is associated with an increased risk of major congenital malformations (MCM).
Methods A population-based birth cohort study using national register data extracted from the Drugs and Pregnancy database in Finland, years 1996–2017. The sampling frame included 1,273,987 pregnant women. We included singleton pregnancies ending in live or stillbirth or termination of pregnancy due to severe malformation. Pregnancies with exposure to known teratogens were excluded. Women were categorized into three groups: exposed to S-GAs (n = 3478), exposed to first-generation antipsychotics (F-GAs) (n = 1030), and unexposed (no purchases of S-GAs or F-GAs during pregnancy, n = 22,540). We excluded genetic conditions and compared the prevalence of MCMs in S-GA users to the two comparison groups using multiple logistic regression models. Results Use of S-GAs during early pregnancy was not associated with an increased risk of overall MCMs compared to unexposed (adjusted odds ratio, OR 0.92; 95% CI 0.72–1.19) or to F-GA users (OR 0.82; 95% CI 0.56–1.20). Of individual S-GAs, olanzapine use was associated with an increased risk of overall MCMs (OR 2.12; 95% CI 1.19–3.76), and specifically, an increased risk of musculoskeletal malformations (OR 3.71; 95% CI 1.35–10.1) when compared to unexposed, while comparisons to F-GA users did not show significant results. Conclusions Olanzapine use is associated with an increased risk of major congenital malformations and specifically, musculoskeletal malformations. Use during pregnancy should be restricted to situations where no safer alternatives exist.

Abstract
OBJECTIVES To explore associations between exposures to medicines prescribed for asthma and their discontinuation in pregnancy and preterm birth [<37 or <32 weeks], SGA [<10th and <3rd centiles], and breastfeeding at 6-8 weeks. METHODS Design. A population-based cohort study. Setting. The Secure Anonymised Information Linkage [SAIL] databank in Wales, linking maternal primary care data with infant outcomes. Population. 107,573, 105,331, and 38,725 infants born 2000-2010 with information on premature birth, SGA and breastfeeding respectively, after exclusions. Exposures. maternal prescriptions for asthma medicines or their discontinuation in pregnancy. Methods. Odds ratios for adverse pregnancy outcomes were calculated for the exposed versus the unexposed population, adjusted for smoking, parity, age and socio-economic status. RESULTS Prescriptions for asthma, whether continued or discontinued during pregnancy, were associated with birth at<32 weeks' gestation, SGA <10th centile, and no breastfeeding (aOR 1.33 [1.10-1.61], 1.10 [1.03-1.18], 0.93 [0.87-1.01]). Discontinuation of asthma medicines in pregnancy was associated with birth at<37 weeks' and <32 weeks' gestation (aOR 1.22 [1.06-1.41], 1.53 [1.11-2.10]). All medicines examined, except ICS and SABA prescribed alone, were associated with SGA <10th centile. CONCLUSIONS Prescription of asthma medicines before or during pregnancy was associated with higher prevalence of adverse perinatal outcomes, particularly if prescriptions were discontinued during pregnancy. Women discontinuing medicines during pregnancy could be identified from prescription records. The impact of targeting close monitoring and breastfeeding support warrants exploration.

Abstract
PURPOSE To identify medications used disproportionately more or less among pregnant women relative to women of childbearing age. METHODS Medication use among pregnant women in New South Wales, Australia was identified using linked perinatal and pharmaceutical dispensing data from 2006 to 2012. Medication use in women of childbearing age (including pregnant women) was identified using pharmaceutical dispensing data for a 10% random sample of the Australian population. Pregnant social security beneficiaries (n = 111 612) were age-matched (1:3) to female social security beneficiaries in the 10% sample. For each medication, the risk it was dispensed during pregnancy relative to being dispensed during an equivalent time period among matched controls was computed. Medications were mapped to Australian pregnancy risk categories. RESULTS Of the 181 included medications, 35 were statistically significantly more commonly dispensed to pregnant women than control women. Of these, 23 are categorised as posing no increased risk to the foetus. Among medications suspected of causing harm or having insufficient safety data, the strongest associations were observed for hydralazine, ondansetron, dalteparin sodium and ranitidine. Use was less likely during pregnancy than control periods for 127 medications, with the strongest associations observed for hormonal contraceptives and progestogens. CONCLUSIONS Most medications found to be used disproportionately more by pregnant women are indicated for pregnancy-related problems. A large number of medications were used disproportionately less among pregnant women, where avoidance of some of these medications may pose a greater risk of harm. For many other medications avoided during pregnancy, current data are insufficient to inform this risk-benefit assessment.

Abstract
Objective To describe prescription medicine dispensing before and during pregnancy in New Zealand, 2005–2015. Methods Members of the New Zealand Pregnancy Cohort were linked with their dispensing records in a national database of prescription products dispensed from community pharmacies. We identified the proportion of pregnancies during which at least one prescription medicine was dispensed, the number of different medicines used and the most commonly dispensed medicine groups both during pregnancy and in the 270 days before conception. Dispensing during pregnancy was assessed by several maternal characteristics. Results 874,884 pregnancies were included. Over the study timeframe, the proportion of pregnancies exposed to a non-supplement prescription medicine increased from 38.5% to 67.2%. The mean number of different non-supplement medicines dispensed during pregnancy increased from 2.5 to 3.2. Dispensing during pregnancy was weakly associated with body mass index, smoking status and ethnicity. Pregnancy exposure was highest for Antibacterials (26.0%), Analgesics (16.7%) and Antinausea & Vertigo Agents (11.0%). Conclusions From 2005–2015, both the proportion of exposed pregnancies and the number of different medicines dispensed to pregnant women in New Zealand increased.

Abstract
Purpose This study aims to illustrate the prevalence and patterns of medication use among pregnant women in mainland China. Patients and methods Hospital and drugstore service data for a nationally representative sample of basic medical insurance (BMI) beneficiaries in 2015 were obtained from the China Health Insurance Association (CHIRA) database. A total of 7946 women who had singleton deliveries in 2015, aged between 12 and 54, and whose records in the CHIRA database covered at least one trimester were included in this study. We conducted descriptive analyses of sample characteristics, medication use prevalence, and number and types of medications used. Results We found that 11.7% of women used at least one medication during the course of pregnancy (median number of medications used = 6.7). Medication use was more common among those who were older, residing in Eastern China, or employed. Most commonly used medication groups by the Anatomical Therapeutic Chemical Classification System were B (Blood and blood forming organs, 49.3%), A (Alimentary tract and metabolism, 48.1%), G (Genito urinary system and sex hormones, 38.1%) and J (Antiinfectives for systemic use, 31.6%). Intravenous solutions, vitamins and minerals, progestogens, and beta-lactam antibacterials were the most frequently used medications from each of these four ATC groups, respectively. Moreover, 7.1% used at least one medication contraindicated in pregnancy. Conclusion This study showed that around one in 10 women used medication during pregnancy in mainland China and found possible cases of inappropriate or unsafe medication use.

Abstract
PURPOSE To evaluate the use of opioids in pregnant primiparous women and study the effect of opioid use on maternal and offspring delivery outcomes. METHODS The study cohort (N = 6231) consists of all primiparous women with a Finnish background who delivered a singleton between 2009 and 2015 in the city of Vantaa, Finland. Data on births, maternal characteristics, pregnancy outcomes, and purchases of prescription drugs were obtained from National Health Registers. RESULTS Of the primiparous women, 5.1% used opioids during pregnancy. Of these, 95.9% used codeine. No differences were observed in purchases of opioids between the different trimesters but more women purchased opioids as pregnancy progressed (.002). Users of opioids more often also purchased other prescription drugs compared with non-users of opioids, 89% versus 58% (P < .001); age, smoking, education, and body mass index adjusted odds ratio 5.66 (95% confidence interval 3.96 to 8.09). Caesarean sections were more common in users of opioids than in non-users, 28.3% versus 21.9% (.007). Before the age of 7 days, the offspring of users of opioids more often needed respirator treatment compared with the offspring of non-users, 3.1% versus 1.6% (.044). CONCLUSIONS One out of 20 pregnant women used opioids. Use of opioids during pregnancy was associated with the risk for deliveries by caesarean sections and need for respiratory treatment among the offspring during the first week of life. Further safety evaluations are needed.

Abstract
OBJECTIVES To assess the prevalence of antiepileptic drug (AED) exposure in pregnant women and the comparative risk of terminations of pregnancy (TOPs), spontaneous abortions, stillbirths, major birth defects (MBDs), neonatal distress and small for gestational age (SGA) infants following intrauterine AED exposure in the Emilia Romagna region, Italy (4 459 246 inhabitants on 31 December 2011). METHODS We identified all deliveries and hospitalised abortions in Emilia Romagna in the period 2009-2011 from the certificate of delivery assistance registry (Certificato di Assistenza al Parto- CedAP) and the hospital discharge card registry, exposure to AEDs from the reimbursed drug prescription registries, MBDs from the regional registry of congenital malformations, and Apgar scores and cases of SGA from the CedAP. Records from different registries were linked. RESULTS We identified 145 243 pregnancies: 111 284 deliveries, 16 408 spontaneous abortions and 17 551 TOPs. Six hundred and eleven pregnancies (0.42%; 95% Cl 0.39 to 0.46) were exposed to AEDs. In the AED-exposed group 21% of pregnancies ended in TOPs vs 12% in the non-exposed women (OR: 2.24; 95% CI 1.41 to 3.56). Rates of spontaneous abortions, stillbirths, neonatal distress and SGA were comparable. Three hundred and fifty-three babies (0.31%; 95% CI 0.28 to 0.35) were exposed to AEDs during the first trimester. MBD rates were 2.3% in the exposed vs 2.0% in the non-exposed pregnancies (OR: 1.12, 95% CI 0.55 to 2.55). CONCLUSION The Emilia Romagna prevalence of AED exposure in pregnancy was 0.42%, comparable with previous European studies. Rates of spontaneous abortions, stillbirths, neonatal distress, SGA and MBDs following AED exposure were not significantly increased. The rate of TOPs was significantly higher in the AED-exposed women.

Abstract
Purpose: To elucidate drug use before and during pregnancy in Japan. Methods: The Japan Environment and Children's Study (JECS) is an ongoing nationwide birth cohort study. We analyzed data from JECS involving cases where drugs were used for 12 months before pregnancy was diagnosed, between the time of diagnosis of pregnancy until week 12 of pregnancy, and after week 12 of pregnancy. Results: We analyzed data from 97,464 pregnant women. The percentages of pregnant women who had taken one or more drugs and supplements before diagnosis of pregnancy, between the time of diagnosis of pregnancy until week 12 of pregnancy, and after week 12 of pregnancy, were 78.4%, 57.1%, and 68.8% respectively. Excluding iron supplements, folic acid, and other vitamins and minerals, the percentages of women taking supplements were 75.3%, 36.0%, and 51.7% at each respective time point. The following drugs and supplements were frequently used for 12 months before pregnancy diagnosis: Commercially available antipyretics, analgesics, and/or medicine for treating common cold (34.7%), antipyretics, analgesics, and/or medicine for treating common colds, which were prescribed in hospitals (29.8%), antimicrobial drugs (14.0%), and anti-allergy drugs (12.5%). The following drugs and supplements were frequently used from the time of pregnancy diagnosis until week 12 of pregnancy, and after week 12 of pregnancy: folic acid (28.9% and 26.2%), antipyretics, analgesics and/or medicines for treating common cold, that were prescribed in hospitals (7.8% and 13.3%), Chinese herbal medicines (6.0% and 9.4%, and uterine relaxants (5.1% and 15.2%). Conclusions: The analysis of a nationwide cohort study showed that a high percentage of Japanese pregnant women were taking medicinal drugs. Further research is required to elucidate the relationship between drug use during pregnancy and birth defects in Japan.

Abstract
Evidence about relationship between antidepressant use during pregnancy and the risk of postpartum hemorrhage (PPH) is conflicting. The aim of this meta-analysis was to systematically assess this relationship. To identify relevant studies, we conducted systematic searches in PubMed and Embase of articles published through May 2016. Random-effects models were adopted to estimate overall relative risk. In total, eight studies involving more than 40,000 PPH cases were included in our meta-analysis. After pooling the estimates, the odds for developing PPH were 1.32-fold higher (risk ratio, RR = 1.32; 95% confidence interval, CI = 1.17-1.48) in antidepressant users compared with individuals who had not taken antidepressants. In subgroup analyses, the associations still exist for women with exposure to non-SRI (RR = 1.31, 95% CI = 1.1-1.56), SRIs (RR = 1.23, 95% CI = 1.06-1.44), SSRIs (RR = 1.2, 95% CI = 1.04-1.38), and SNRIs (RR = 1.62, 95% CI = 1.41-1.85). Based on exposure window, we found an increased risk of PPH among current (RR = 1.37, 95% CI = 1.09-1.71) and recent users (RR = 1.32, 95% CI = 1.15-1.51), but not past users (RR = 1.08, 95% CI = 0.88-1.31). The findings of this meta-analysis support an increased risk of PPH in women exposure to antidepressant during late gestation.

Prescription patterns of antiepileptic drugs in young women: development of a tool to distinguish between epilepsy and psychiatric disorders. Pharmacoepidemiol Drug Saf 2016; 25:763-9. [PMID: 26887800 DOI: 10.1002/pds.3984] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2015] [Revised: 01/15/2016] [Accepted: 01/17/2016] [Indexed: 12/22/2022]
Abstract
BACKGROUND Antiepileptic drugs (AEDs) are also prescribed for therapeutic indications other than epilepsy (EPI), namely, psychiatric disorders (PSY). Our aim was to develop an algorithm able to distinguish between EPI and PSY among childbearing age women based on differences in AED exposure in these patient groups. METHODS Two groups of women (18-45 years) with EPI or PSY treated with AEDs in the first semester of 2010 or 2011 were extracted from paper or electronic medical charts of specialized centers. Through the prescription database of Bologna Local Health Authority (Italy), AEDs, treatment schedule and co-treatments were collected for each patient. A prescription-based hierarchical classification system was developed. The algorithm obtained was subsequently validated on internal and external data. RESULTS Eighty-one EPI and 94 PSY subjects were recruited. AED monotherapy was the most common choice in both groups (69% EPI vs 79% PSY). Some AEDs were used only in EPI, others exclusively in PSY. Co-treatments with antipsychotics (6% vs 67%), lithium (0% vs 9%), and antidepressants (7% vs 70%) were fewer in EPI than in PSY. The hierarchical classification system identified antipsychotics, SSRIs (Selective Serotonin Reuptake Inhibitors), and number of AEDs as variables to discriminate EPI and PSY, with an overall error rate estimate of 9.7% (95%CI: 5.3% to 14.1%). CONCLUSION Among the differences between EPI and PSY, prescription data alone allowed an algorithm to be developed to diagnose each childbearing age woman receiving AEDs. This approach will be useful to stratify patients for risk estimates of AED-treated patients based on administrative databases. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
The objectives of this article are to systematically review i) the extent of medicine use in postpartum women, and ii) the impact of maternal medicine use (excluding contraceptives and galactogogues) on breastfeeding outcomes (initiation and/or duration). PubMed, Medline (Ovid), Scopus (Elsevier), Cinahl (EBSCO), PsycINFO (Ovid), Embase (Ovid) and Web of Science (ISI) databases were searched to find original studies on medicine use in women after the birth. Additional studies were identified by searching Google Scholar, Wiley Online Library, Springer Link, selected journals and from the reference list of retrieved articles. Observational studies with information about postpartum women's use of any type of medicine either for chronic or acute illnesses with or without breastfeeding information were included. The majority of relevant studies suggest that more than 50 % of postpartum women (breastfeeding or not) required at least one medicine. Due to the lack of uniform medication use reporting system and differences in study designs, settings and samples, the proportion of medicine use by postpartum women varies widely, from 34 to 100 %. Regarding the impact of postpartum women's medicine use on breastfeeding, a few studies suggest that women's use of certain medicines (e.g. antiepileptics, propylthiouracil, antibiotics) during lactation can reduce initiation and/ or duration of breastfeeding. These studies are limited by small sample size, and with one exception, all were conducted in Canada more than a decade ago. Large scale studies are required to establish the relationship between maternal medicine use and breastfeeding, considering type of illness, period of use and total duration of medicine use.

Abstract
Research on psychotropic medications during pregnancy and lactation is limited as often involves complex ethical issues. Information on safety of psychotropic drugs during these critical phases is either inconclusive or undetermined. Many women with severe mental illness have unplanned pregnancies and require antipsychotic medication during pregnancy and lactation. Multiple issues have to be considered while choosing safe treatments for pregnant and lactating women and the best approach is to individualize the treatment. Medication should be guided primarily by its safety data and by the psychiatric history of the patient. Important issues to be kept in mind include pre-pregnancy counseling for all women, including planning pregnancies; folate supplementation, discussion with patient and family regarding options, and active liaison with obstetricians, ultrasonologists and pediatricians. Whenever possible, non-pharmacological approaches should be used in addition.

Abstract
Purpose To describe trends, patterns, and determinants of prescription drug use during pregnancy and postpartum. Methods This is a retrospective, population-based study of all women who gave birth between January 2002 and 31 December 2011 in British Columbia, Canada. Study population consisted of 225,973 women who had 322,219 pregnancies. We examined administrative datasets containing person-specific information on filled prescriptions, hospitalizations, and medical services. Main outcome measures were filled prescriptions during pregnancy and postpartum. We used logistic regressions to examine associations between prescription drug use and maternal characteristics. Results Approximately two thirds of women filled a prescription during pregnancy, increasing from 60% in 2002 to 66% in 2011. The proportion of pregnant women using medicines in all three trimesters of pregnancy increased from 20% in 2002 to 27% in 2011. Use of four or more different types of prescription drug during at least one trimester increased from 8.4% in 2002 to 11.7% in 2011. Higher BMI, smoking during pregnancy, age under 25, carrying multiples, and being diagnosed with a chronic condition all significantly increased the odds of prescription drug use during pregnancy. Conclusions The observed increase in the number of prescriptions and number of different drugs being dispensed suggests a trend in prescribing practices with potentially important implications for mothers, their neonates, and caregivers. Monitoring of prescribing practices and further research into the safety of most commonly prescribed medications is crucial in better understanding risks and benefits to the fetus and the mother.

Abstract
PURPOSE The aim was to investigate the prevalence of eating disorders and its relation to pregnancy and delivery complications in childbearing women with epilepsy (WWE). METHOD This study is based on The Norwegian Mother and Child Cohort Study (MoBa) linked to the Medical Birth Registry of Norway. Epilepsy was reported in 706 pregnancies. The remaining cohort (n=106,511) served as the reference group. Eating disorders were diagnosed using DSM-IV criteria adjusted for pregnancy. The risk of preeclampsia, gestational hypertension, diabetes and weight gain during pregnancy as well as delivery outcome (small for gestational age, large for gestational age, ponderal index, low APGAR score, small head circumference) were calculated as odds ratios (ORs) with 95% confidence intervals (CIs) adjusted for maternal age, smoking, parity and socioeconomic factors. RESULTS Pregnant WWE were significantly more likely to have binge eating disorder (6.5% vs. 4.7%, p<0.05). WWE and comorbid eating disorders had significantly more preeclampsia (7.9% vs. 3.7%, p<0.05), peripartum depression and/or anxiety (40.4% vs. 17.8%, p<0.001) and operative delivery (38.2% vs. 23.5%, p<0.001) than the reference group without epilepsy or eating disorders. After adjustment for confounders, a significantly increased risk of operative delivery (OR 1.96, CI 1.26-3.05) and peripartum depression and/or anxiety (OR 2.17, CI 1.40-3.36) was demonstrated. CONCLUSION Eating disorders in WWE contribute to the increased risk of pregnancy and delivery complications. Health personnel should be aware of eating disorders in WWE and refer them for treatment before pregnancy.

Abstract
Background Drug use during pregnancy may be dangerous to the fetus. There is high consumption of prescribed drugs among pregnant women. This condition may be much higher in developing countries. There is no sufficient evidence on prescribed drug use among pregnant women in Bahir Dar town. The aim of this study was to assess the level of prescribed drug use and associated factors among pregnant women attending antenatal care (ANC) service at government health centers in Bahir Dar city administration. Methods Institution based cross sectional study was used. Data were collected from randomly selected 510 pregnant women. Data were analyzed using SPSS version 16.0. Back ward stepwise logistic regression model was used and p-values <0.05 were considered statistically significant. Result A total of 510 pregnant women were included in the study of which 88.4% were prescribed at least one drug during pregnancy. Nearly 11% of the pregnant women were prescribed with drugs from category D or X of the US-FDA risk classification. Prescribed drug use among pregnant women was more likely when the pregnancy is wanted, (AOR = 2.4, 95% CI: 1.3 - 4.6), if the mother had maternal illness (AOR = 8.5, 95% CI: 5.4-13.4), when the educational level of ANC provider is diploma (AOR = 2.7, 95% CI: 1.5-4.7) and when number of pregnancies is more (AOR =2.1, 95% CI: 1.3-3.3). Conclusion Prescribed drug use including those with potential harm to the fetus during pregnancy was very high in Bahir Dar city administration. Prescribed drug use is more when the woman had illness, when the woman was multi gravida and when the educational level of ANC provider was low (diploma). It is important to upgrade providers’ educational level and institute prevention of diseases like malaria to reduce the level of prescribed drug use during pregnancy.

Abstract
The objective of this review is to describe the possibilities to assess drugs used in pregnancy by means of the Nordic health registers. The Nordic countries comprise five countries: Denmark, Finland, Iceland, Norway and Sweden and have a total population of 25 million. All five countries have in their national health registers for many years recorded information concerning all births, cancer diagnoses, hospital contacts, causes of death and dispensed drugs. The registers can be used for studying drugs dispensed during pregnancy and though most previous studies focused on risks of congenital abnormalities, other health consequences of maternal medication can also be assessed.

Abstract
OBJECTIVES Intercountry comparability between studies on medication use in pregnancy is difficult due to dissimilarities in study design and methodology. This study aimed to examine patterns and factors associated with medications use in pregnancy from a multinational perspective, with emphasis on type of medication utilised and indication for use. DESIGN Cross-sectional, web-based study performed within the period from 1 October 2011 to 29 February 2012. Uniform collection of drug utilisation data was performed via an anonymous online questionnaire. SETTING Multinational study in Europe (Western, Northern and Eastern), North and South America and Australia. PARTICIPANTS Pregnant women and new mothers with children less than 1 year of age. PRIMARY AND SECONDARY OUTCOME MEASURES Prevalence of and factors associated with medication use for acute/short-term illnesses, chronic/long-term disorders and over-the-counter (OTC) medication use. RESULTS The study population included 9459 women, of which 81.2% reported use of at least one medication (prescribed or OTC) during pregnancy. Overall, OTC medication use occurred in 66.9% of the pregnancies, whereas 68.4% and 17% of women reported use of at least one medication for treatment of acute/short-term illnesses and chronic/long-term disorders, respectively. The extent of self-reported medicated illnesses and types of medication used by indication varied across regions, especially in relation to urinary tract infections, depression or OTC nasal sprays. Women with higher age or lower educational level, housewives or women with an unplanned pregnancy were those most often reporting use of medication for chronic/long-term disorders. Immigrant women in Western (adjusted OR (aOR): 0.55, 95% CI 0.34 to 0.87) and Northern Europe (aOR: 0.50, 95% CI 0.31 to 0.83) were less likely to report use of medication for chronic/long-term disorders during pregnancy than non-immigrants. CONCLUSIONS In this study, the majority of women in Europe, North America, South America and Australia used at least one medication during pregnancy. There was a substantial inter-region variability in the types of medication used.

Use of medicines with unknown fetal risk among parturient women from the 2004 Pelotas Birth Cohort (Brazil). J Pregnancy 2012; 2012:257597. [PMID: 23346403 PMCID: PMC3549362 DOI: 10.1155/2012/257597] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2012] [Revised: 11/25/2012] [Accepted: 11/26/2012] [Indexed: 11/18/2022] Open
Abstract
Background. To estimate the exposure to medicines with unknown fetal risk during pregnancy and to analyze the maternal characteristics associated with it. Methods. A questionnaire was administered to 4,189 mothers of children belonging to the 2004 Pelotas (Brazil) birth cohort study about use of any medicine during gestation. We evaluated the associations between use of medicines with unknown fetal risk and the independent variables through logistic regression models. Unknown fetal risk was defined as medicines in which studies in animals have revealed adverse effects on the fetus, and no controlled studies in women, or studies in women and animals, are available. Results. Out of the 4,189 women, 52.5% used at least one medicine from unknown fetal risk. Use of these medicines was associated with white skin color, high schooling, high income, six or more antenatal care consultations, hospital admission during pregnancy, and morbidity during gestation. Conclusion. The use of unknown fetal risk medicines is high, suggesting that their use must be addressed with caution with the aim of restricting their use to cases in which the benefits are greater than the potential risks.

Abstract
BACKGROUND It is important to control asthma during pregnancy. However, some studies indicate that women stop or change their asthma medications when they become pregnant. OBJECTIVE We used a population database to analyze changes in prescriptions for asthma medications to patients before, during, and after pregnancy. METHODS We collected information from a pregnancy database that is part of the population-based pharmacy prescription InterAction Database from the northern Netherlands. Our study cohort comprised 25,709 pregnancies for which prescription data were available. We collected data over a study period of 1 year before pregnancy until 6 months after birth and analyzed data from pregnant women who received at least 1 prescription for asthma medication during the study period (n = 2072), identifying all prescriptions for asthma medication and oral corticosteroids. RESULTS Prescriptions for asthma medications did not change during pregnancies from 1994-2003. However, during the 2004-2009 period, there was a significant decrease (P = .017) in prescriptions for asthma medications during the first months of pregnancy compared with the months before pregnancy, especially prescriptions of long-acting bronchodilators. Although most asthma prescriptions continued throughout pregnancy, prescriptions for controller therapies were reduced by 30% during the first months of pregnancy. CONCLUSIONS Many women stop or reduce their use of asthma medications when they become pregnant. Strategies to safely control asthma during pregnancy are needed.

Abstract
BACKGROUND Observation of drug use patterns during pregnancy is necessary for the recognition of potential bad practices and improvement of safe drug use in pregnancy. OBJECTIVE To investigate prescription and over the counter drug use among Serbian women in the 6 months before pregnancy and in the first 6 months of pregnancy, and to evaluate the drugs used according to the risk to a fetus. Setting Six maternity care units and five community pharmacies. METHOD A multi-center study was performed in Serbia during the period from March 2009-March 2010. A self-reporting questionnaire was used as a data source. Food and Drug Administration (FDA) risk classification system was used to determine the risk of used drugs for the fetus. Differences between subgroups were assessed using McNemar's test on paired proportions. Main outcome measure Proportion of women exposed to drugs or class of drugs. RESULTS The overall drug exposure was higher in pregnancy (34.7 %) than before pregnancy (29.9 %), p > 0.05, in the cohort of 311 pregnant women. A significantly greater prescription drug use, 19.0 versus 27.3 % of women, p < 0.05, and less selfmedication with over the counter drugs in pregnancy, 15.1 versus 8.7 %, p < 0.05, were observed. Commonly used drugs were musculoskeletal drugs, analgesics/antipyretics and respiratory system drugs before pregnancy (13.8, 12.5, and 6.4 % of women, respectively), and progestogens, analgesics/antipyretics, and antibiotics for the systemic use in pregnancy (9.0, 7.7, and 7.4 %, respectively). A greater exposure to drugs belonging to the FDA risk category A (3.9 vs. 60.8 %, p < 0.05), B (18.0 vs. 19.6 %, p > 0.05), C (10.0 vs. 10.3 %, p > 0.05) and D (2.9 vs. 10.9 %, p < 0.05), as well as less exposure to drugs belonging to category X (0.3 vs. 0 %, p > 0.05) were observed in pregnancy. Folic acid was used by 60.8 % of women in pregnancy, and by only 3.9 % before pregnancy. CONCLUSION Besides higher overall drug use in pregnancy than before pregnancy, particularly the use of progestogens, and, subsequently, D category drugs, less selfmedication with over the counter drugs was observed in pregnancy. Insufficient use of folic acid before pregnancy requires public health service activities.

Abstract
OBJECTIVE The aims of this study were (a) to describe the sociodemographic and clinical profile of women with unplanned pregnancies and consequent exposure to psychotropic drugs, (b) to describe the nature and timing of psychotropic exposure during pregnancy among these women, and (c) to examine the outcome of decisions related to pregnancy following consultation at a perinatal psychiatric service. MATERIALS AND METHODS WOMEN ATTENDING THE PERINATAL PSYCHIATRY SERVICES REFERRED FOR ACCIDENTAL EXPOSURE TO PSYCHOTROPICS WERE ASSESSED BY STRUCTURED INTERVIEWS FOR THE FOLLOWING DETAILS: sociodemographic details, clinical details, psychotropic drug use, advice given in the clinic, and outcome related to this advice. RESULTS Fifty-three women were referred for counseling related to unplanned pregnancies and consequential psychotropic exposure. Forty-two women (79%) sought consultation in the first trimester. More than a third of the women, 19 (36%), were taking more than one psychotropic medication during the first consultation. Only 11 (20%) women had received any form of prepregnancy counseling prior to becoming pregnant. Of the 37 women who came for follow-up in the clinic, 35 (94%) of them continued the pregnancy. CONCLUSIONS Unplanned pregnancies in women with mental illness are common and result in exposure to multiple psychotropic medications during the first trimester. Majority of women did not report of having prepregnancy counseling and which needs to be an integral part of treatment and education.

Abstract
BACKGROUND Owing to the paucity of evidence available on the risks and benefits of drug use in pregnancy, the use of prescription medicines is a concern for both pregnant women and their health care providers. OBJECTIVE The aim of this study was to measure the frequency, timing, and type of medicines used before, during, and after pregnancy in a Canadian population. METHODS This retrospective cohort analysis used population-based health care data from all pregnancies ending in live births in hospitals in British Columbia from April 2001 to June 2006 (n = 163,082). Data from hospital records were linked to those in outpatient prescription-drug claims. Data from prescriptions filled from 6 months before pregnancy to 6 months postpartum were analyzed. Drugs were classified by therapeutic category and US Food and Drug Administration (FDA) pregnancy risk categories. RESULTS Prescriptions were filled in 63.5% of pregnancies. Evidence on safety is limited for many of the medicines most frequently filled in pregnancy, including codeine, salbutamol, and betamethasone. At least 1 prescription for a category D or X medicine was filled in 7.8% of pregnancies (5.5% category D; 2.5% category X). The most frequently filled prescriptions for category D drugs were benzodiazepines and antidepressants. The most frequently filled prescriptions for category X drugs were oral contraceptives and ovulation stimulants filled in the first trimester. CONCLUSIONS The majority of pregnant women in British Columbia filled at least 1 prescription, and ~1 in 13 filled a prescription for a drug categorized as D or X by the FDA. The prevalence of maternal prescription drug use emphasizes the need for postmarketing evaluation of the risk-benefit profiles of pharmaceuticals in pregnancy. Future research on prenatal drug use based on administrative databases should examine maternal treatment adherence and the determinants of maternal drug use, considering maternal health status, sociodemographics, and the characteristics and providers of prenatal care.

Selective serotonin reuptake inhibitors in human pregnancy: to treat or not to treat? Obstet Gynecol Int 2011; 2012:698947. [PMID: 22190957 PMCID: PMC3236415 DOI: 10.1155/2012/698947] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2011] [Revised: 10/05/2011] [Accepted: 10/07/2011] [Indexed: 11/18/2022] Open
Abstract
Selective serotonin reuptake inhibitors (SSRIs) are increasingly prescribed during pregnancy. The purpose of the present paper is to summarize and evaluate the current evidence for the risk/benefit analysis of SSRI use in human pregnancy. The literature has been inconsistent. Although most studies have not shown an increase in the overall risk of major malformations, several studies have suggested that SSRIs may be associated with a small increased risk for cardiovascular malformations. Others have noted associations between SSRIs and specific types of rare major malformations. In some studies, there appears to be a small increased risk for miscarriages, which may be associated with the underlying maternal condition. Neonatal effects have been described in up to 30% of neonates exposed to SSRIs late in pregnancy. Persistent pulmonary hypertension of the newborn has also been described with an absolute risk of <1%. The risk associated with treatment discontinuation, for example, higher frequency of relapse and increased risk of preterm delivery, should also be considered. The overall benefit of treatment seems to outweigh the potential risks.

Abstract
PURPOSE To review the literature describing patterns of outpatient prescription drug use during pregnancy by therapeutic category, potential for fetal harm, and overall. METHODS We conducted a systematic review of peer-reviewed literature published from 1989 to 2010. We included studies evaluating individual-level exposures to prescription medicines during pregnancy. We selected only studies conducted in developed (Organization of Economic Co-operation and Development) countries and published in English. RESULTS Published drug utilization studies reveal wide variation in estimates of overall prescription drug use in pregnancy (27-93% of pregnant women filling at least one prescription excluding vitamins and minerals). Among studies of similar design, estimates were lowest in Northern European countries (44-47%) and highest in France (93%) and Germany (85%). Measured rates of use of contraindicated medicines in pregnancy ranged from 0.9% (Denmark, 1991-1996) to 4.6% (USA, 1996-2000). The use of medicines with positive evidence of risk ranged from 2.0% (Italy, 2004) to 59.3% (France, 1996). CONCLUSION Avoidable inconsistencies in study design and reporting attenuate conclusions that can be drawn from the literature on antenatal drug utilization. Nevertheless, the body of published research shows that antenatal prescription drug use is common, with many studies finding that a majority of women use one or more prescription medicine during pregnancy. Similarly, studies consistently report the use of drugs recognized as having potential risks in pregnancy. Given this widespread use, it is particularly important to develop standards for calculating and reporting antenatal exposures to improve the value of future research in this area.

Abstract
PURPOSE The aim of this population-based nationwide drugs and pregnancy surveillance system was to get basic information on the use of prescribed drugs during pregnancy and to achieve more detailed information on drug exposure-outcome associations with data obtained from the Finnish national health registers. METHODS The data are based on information on all pregnancies ending in births (n = 632,629) or termination of pregnancy (TOP) (n = 117,255) in Finland between 1996 and 2006. The data containing information on maternal background factors, chronic diseases and drug purchases during pregnancy, born children, induced abortions, perinatal health and major congenital malformations were obtained from the Finnish national health registers. Information from the different registers was merged through record linkages based on unique personal identification numbers. Statistical analyses were conducted between the exposed and unexposed for individual drugs or Anatomical Therapeutic Chemical (ATC) classification drug groups in multivariate logistic regression including potential confounding factors. RESULTS Nearly half of parturients and almost every third woman with TOP purchased drugs at least once 1 month prior to pregnancy and/or during pregnancy. The most frequent chronic diseases during pregnancy were asthma, hypothyroidism, epilepsy, rheumatoid arthritis and diabetes. Previously known causal connections between maternal chronic diseases and/or medication and perinatal health risks were already seen in the ATC-group-level analysis. CONCLUSIONS Comprehensive and detailed information for pharmacoepidemiological research on the effects of drug use during pregnancy in a cohort setting is possible with long-term and cumulative data collection.

Abstract
PURPOSE To describe patterns of prescribed drug use over time among primiparous women in Denmark. METHODS Through the Danish Medical Birth Registry, we identified all primiparous women giving live birth or stillbirth at ≥ 22 gestational weeks in northern Denmark, from 1999 to 2009. From the Aarhus University Prescription Database we obtained information on the women's prescriptions for reimbursed drugs filled from 30 days before conception until delivery. RESULTS Among 85,710 primiparous women, 47,982 (56.0%) redeemed at least one prescription from 30 days before conception until delivery. Women aged 35 years and older had the highest overall prevalence of prescription drug use (61.1%). Age-standardized prevalence of drug use was 54.7% in 1999 and 61.2% in 2009, prevalence ratio (PR) of 1.13 (95% confidence interval 1.10; 1.16), adjusted for age and smoking. CONCLUSION Over the 11-year period from 1999 to 2009, we found a modest increase in overall use of drugs by primiparous women in Denmark. This increase was not, however, explained by an increasing proportion of older first-time mothers. We noted changes in patterns of use of anti-infective drugs and antidepressants.

Abstract
Purpose: The purpose of this research is to study drug use during pregnancy in Sweden and agreement between use according to antenatal medical records and dispensed drugs from a pharmacy database. Patients and methods: From the Swedish Medical Birth Register (MBR), we established a population-based cohort of 102,995 women who gave birth in 2007. Using the unique personal registration number, information on dispensed drugs from the Prescribed Drug Register (PDR) was obtained prior to, during, and after the pregnancies and compared with MBR information on drug use from standardized antenatal medical records. Results: According to the PDR, 57.6% of the 102,995 women filled a prescription with at least one drug during pregnancy and 50.9% during the lactating period (until 3 months after delivery). The most dispensed drugs during pregnancy were B-lactam antibacterials and penicillins. Agreement between drugs recorded in antenatal medical records and dispensed drugs was highest for drugs used for chronic conditions. The agreement was particularly high for thyroid therapy (85.3%), anti-intestinal inflammatory drugs (80.3%), antiepileptics (69.2%), immunosuppressants (67.4%), and insulin (63.8%). Agreement for drugs used for occasional use was generally lower, ranging between 42.5% for antihistamines and 0.8% for gynecological anti-infectives. Conclusions: A large proportion of women filled a prescription during pregnancy or the lactating period. Agreement between drug use in medical antenatal records and register information from a national pharmacy database was high for drugs used for chronic conditions but low for occasional use. For occasionally used drugs, medical record and register-based data may provide incomplete exposure information because of nonreporting or noncompliance.

Abstract
PURPOSE Maternal medication use during pregnancy is explored extensively, as it may cause birth defects. This study aimed to evaluate the validity of recorded medication use in the Medical Birth Registry of Norway (MBRN). METHODS This study was based on the nationwide population-based registries, the MBRN and the Norwegian Prescription Database (NorPD). These registries were linked using a unique 11-digit identification number. The sensitivity, specificity and positive predictive value (PPV) of recorded medication use in MBRN were computed using data from NorPD as the reference. RESULTS Among the 163,678 pregnancies included in our study, the sensitivity for total drug use during pregnancy was calculated to be 32% and PPV was 82%. When we looked at the use of medication during the whole pregnancy, the sensitivities of drug registration for the main groups in the Anatomical Therapeutic Chemical (ATC)-classification varied from 50% (ATC group H) to 2% (ATC group S). CONCLUSION The medication use recorded in MBRN is poor compared with prescribed medicines registered in NorPD. There was a substantial difference between the different ATC codes regarding the sensitivity of MBRN in the registration of medication use during pregnancy.

Abstract
To illustrate the process of addressing adverse preclinical findings (APFs) as
outlined in the first part of this review, a number of cases with unexpected APF
in toxicity studies with drug candidates is discussed in this second part. The
emphasis is on risk characterization, especially regarding the mode of action
(MoA), and risk evaluation regarding relevance for man. While severe APFs such
as retinal toxicity may turn out to be of little human relevance, minor findings
particularly in early toxicity studies, such as vasculitis, may later pose a
real problem. Rodents are imperfect models for endocrine APFs, non-rodents for
human cardiac effects. Liver and kidney toxicities are frequent, but they can
often be monitored in man and do not necessarily result in early termination of
drug candidates. Novel findings such as the unusual lesions in the
gastrointestinal tract and the bones presented in this review can be difficult
to explain. It will be shown that well known issues such as phospholipidosis and
carcinogenicity by agonists of peroxisome proliferator-activated receptors
(PPAR) need to be evaluated on a case-by-case basis. The latter is of particular
interest because the new PPAR α and dual α/γ agonists resulted in a change of
the safety paradigm established with the older PPAR α agonists. General
toxicologists and pathologists need some understanding of the principles of
genotoxicity and reproductive toxicity testing. Both types of preclinical
toxicities are major APF and clinical monitoring is difficult, generally leading
to permanent use restrictions.

Abstract
PURPOSE To examine the extent, nature and determinants of medication use in early pregnancy. METHODS We reviewed early pregnancy medication use, as reported to a midwife at the booking interview, in women delivering between 2000 and 2007 in a large maternity hospital in Dublin, Ireland (n = 61 252). RESULTS Excluding folic acid, at least one medication was reported in 23 989 (39.2%) pregnancies. Over the counter (OTC) medications were reported in 11 970 (19.5%) pregnancies, illicit drugs or methadone in 545 (0.9%) and herbal medicines/supplements in 352 (0.58%). FDA category D and X medications were reported by 1532 (2.5%) and 1987 (3.2%) women. Asthma, depression and hypertension were among the most commonly reported chronic medical disorders. Medications with potential for foetal harm were reported by 86 (15.7%) women treated for depression and 68 (20%) women treated for hypertension. Factors associated with reporting the use of medications with potential for foetal harm included unplanned pregnancy (adjusted odds ratio [aOR] 1.31, 95% confidence interval [CI] 1.12-1.52), booking at less than 12 weeks gestation (aOR 1.83, 95%CI 1.58-2.13), being above 25 years of age, unemployed (aOR 2.58, 95%CI 2.03-3.29), nulliparous (aOR 1.41; 95%CI 1.22-1.63), single (aOR 1.28; 95%CI 1.06-1.54) or smoking during pregnancy (aOR 1.96, 95%CI 1.67-2.28). CONCLUSIONS Women frequently report medication use in early pregnancy. Women and prescribers need to be aware of the lack of pregnancy safety data for many medications, and the need for pre-pregnancy planning. Prescribers should ensure that optimal medications are used when treating women of childbearing potential with chronic medical disorders.

Abstract
AIMS Recent studies have suggested a possible association between maternal use of selective serotonin reuptake inhibitors (SSRIs) in early pregnancy and cardiovascular anomalies. The aim of the present study was to evaluate the teratogenic risk of paroxetine and fluoxetine. METHODS This multicentre, prospective, controlled study evaluated the rate of major congenital anomalies after first-trimester gestational exposure to paroxetine, fluoxetine or nonteratogens. RESULTS We followed up 410 paroxetine, 314 fluoxetine first-trimester exposed pregnancies and 1467 controls. After exclusion of genetic and cytogenetic anomalies, there was a higher rate of major anomalies in the SSRI groups compared with the controls [paroxetine 18/348 (5.2%), fluoxetine 12/253 (4.7%) and controls 34/1359 (2.5%)]. The main risk applied to cardiovascular anomalies [paroxetine 7/348 (2.0%), crude odds ratio (OR) 3.47, 95% confidence interval (CI) 1.13, 10.58; fluoxetine 7/253 (2.8%), crude OR, 4.81 95% CI 1.56, 14.71; and controls 8/1359 (0.6%)]. On logistic regression analysis only cigarette smoking of >or=10 cigarettes day(-1) and fluoxetine exposure were significant variables for cardiovascular anomalies. The adjusted ORs for paroxetine and fluoxetine were 2.66 (95% CI 0.80, 8.90) and 4.47 (95% CI 1.31, 15.27), respectively. CONCLUSION This study suggests a possible association between cardiovascular anomalies and first-trimester exposure to fluoxetine.
