Paroxetine use during breast-feeding

Consensus Panel Recommendations for the Pharmacological Management of Breastfeeding Women with Postpartum Depression

INTRODUCTION

Our consensus statement aims to clarify the use of antidepressants and anxiolytics during breastfeeding amidst clinical uncertainty. Despite recent studies, potential harm to breastfed newborns from these medications remains a concern, leading to abrupt discontinuation of necessary treatments or exclusive formula feeding, depriving newborns of benefits from mother's milk.

METHODS

A panel of 16 experts, representing eight scientific societies with a keen interest in postpartum depression, was convened. Utilizing the Nominal Group Technique and following a comprehensive literature review, a consensus statement on the pharmacological treatment of breastfeeding women with depressive disorders was achieved.

RESULTS

Four key research areas were delineated: (1) The imperative to address depressive and anxiety disorders during lactation, pinpointing the risks linked to untreated maternal depression during this period. (2) The evaluation of the cumulative risk of unfavorable infant outcomes associated with exposure to antidepressants or anxiolytics. (3) The long-term impact on infants' cognitive development or behavior due to exposure to these medications during breastfeeding. (4) The assessment of pharmacological interventions for opioid abuse in lactating women diagnosed with depressive disorders.

CONCLUSIONS

The ensuing recommendations were as follows: Recommendation 1: Depressive and anxiety disorders, as well as their pharmacological treatment, are not contraindications for breastfeeding. Recommendation 2: The Panel advocates for the continuation of medication that has demonstrated efficacy during pregnancy. If initiating an antidepressant during breastfeeding is necessary, drugs with a superior safety profile and substantial epidemiological data, such as SSRIs, should be favored and prescribed at the lowest effective dose. Recommendation 3: For the short-term alleviation of anxiety symptoms and sleep disturbances, the Panel determined that benzodiazepines can be administered during breastfeeding. Recommendation 4: The Panel advises against discontinuing opioid abuse treatment during breastfeeding. Recommendation 5: The Panel endorses collaboration among specialists (e.g., psychiatrists, pediatricians, toxicologists), promoting multidisciplinary care whenever feasible. Coordination with the general practitioner is also recommended.

Antidepressant transfer into amniotic fluid, umbilical cord blood & breast milk: A systematic review & combined analysis

OBJECTIVE

Data regarding the ability of antidepressants to enter fetal, newborn and infant fluids have become gradually available, but mechanisms of antidepressant transfer remain poorly understood. Here we calculated penetration ratios in an array of matrices from combined samples of pregnant/breastfeeding women taking antidepressants.

METHOD

We performed a systematic literature search of PubMed and EMBASE to identify studies with concentrations of antidepressants from maternal blood, amniotic fluid, umbilical cord blood and/or breast milk. Penetration ratios were calculated by dividing the concentrations in amniotic fluid, umbilical cord plasma or breast milk by the maternal plasma concentration. When data from multiple studies were available, we calculated combined penetration ratios, weighting the study mean by study size.

RESULTS

Eighty-five eligible studies were identified. For amniotic fluid, the highest penetration ratios were estimated for venlafaxine (mean 2.77, range 0.43-4.70 for the active moiety) and citalopram (mean 2.03, range 0.35-6.97), while the lowest ratios were for fluvoxamine (mean 0.10) and fluoxetine (mean 0.11, range 0.02-0.20 for the active moiety). For umbilical cord plasma, nortriptyline had the highest ratio (mean 2.97, range 0.25-26.43) followed by bupropion (mean 1.14, range 0.3-5.08). For breast milk, the highest ratios were observed for venlafaxine (mean 2.59, range 0.85-4.85), mianserin (mean 2.22, range 0.80-3.64) and escitalopram (mean 2.19, range 1.68-3.00).

CONCLUSION

We observed considerable variability across antidepressants regarding their ability to enter fetal, newborn and infant fluids. Measuring antidepressant concentrations in a maternal blood sample can provide a reliable estimate of fetal/infant exposure, although further evidence for concentration-dependent effects is required.

Panic disorder during pregnancy and postpartum period

Background

– Earlier studies on the influence of pregnancy and postpartum period on the course of panic disorder have been inconsistent. The present study aims to quantify panic manifestations in these periods in large sample of women.

Method

– Panic manifestations, including exacerbations and new manifestations of panic disorder, were assessed retrospectively in a sample of 128 women with panic disorder with or without agoraphobia, 93 of whom had had 195 pregnancies.

Results

– Panic manifestations were fewer during pregnancy and more frequent in the postpartum period when compared with the control period. Women who had never been pregnant had significantly more panic manifestations than women with prior pregnancies. Breastfeeding and miscarriages did not have a significant effect. Women with postpartum panic reported more psychosocial stress events during this period.

Conclusions

– Possible reasons for postpartum panic and the protective effects of pregnancy are discussed, including psychosocial or hormonal factors and other neurobiological changes. Postpartum panic coincides with a sudden drop of hormones after delivery.

Quality of Lactation Studies Investigating Antidepressants

Introduction: The aim of this study was to determine the quality of lactation studies investigating antidepressants in breast milk according to the Food and Drug Administration (FDA) draft guidelines and the article by Begg et al., 2002, published in the official journal of the International Lactation Consultant Association (ILCA). Materials and Methods: We used PubMed and LactMed^® for the literature search. Furthermore, cross references were searched for additional studies. Results: A total number of 60 articles were included for review. For selective serotonin reuptake inhibitors and venlafaxine, only two studies correctly assessed the absolute infant dose and milk to plasma ratio; one sertraline and one fluoxetine study. Of all tricyclic antidepressants, one study for amitriptyline and one for nortriptyline assessed these endpoints correctly. We found a lack of information on breast milk sampling methods in many studies. Concentrations needed for the calculations were based on single measurements instead of at least five measurements during one dose interval, and the relative infant dose was not normalized by maternal weight, or an average maternal weight of 70 kg was used as a standard. Discussion: We conclude that the quality of the current literature on this topic does not meet the standards of the FDA. Studies of higher quality are needed to determine the extent of drug transfer to breast milk for antidepressants, so an adequate recommendation about use of these drugs during lactation can be given.

Medications and Breast-Feeding: A Guide for Pharmacists, Pharmacy Technicians, and other Healthcare Professionals Part III

Objective:

To provide a guide for practicing pharmacists, pharmacy technicians, and other healthcare professionals so that they are able to counsel and advise breast-feeding mothers and fellow healthcare professionals on the safety and use of antiinfectives, vaccines, antiepileptics, benzodiazepines, psychotherapeutic drugs, and radiopharmaceuticals during breast-feeding.

Data Sources:

Primary texts used by the breast-feeding community ( Medications and Mothers' Milk, Drugs in Pregnancy and Lactation, Drugs and Human Lactation) were searched, as well as Micromedex, MEDLINE, PubMed, EMBASE, and EMBASE2 (1984–February 2004).

Study Selection/Data Extraction:

Multiple sources were used wherever available to validate the data, and primary articles were used to verify all tertiary source information. Search terms included breast-feeding, lactation, nursing, and medications, as well as specific drug names.

Data Synthesis:

Concerns regarding medication use during breast-feeding have caused mothers to either discontinue nursing or not take necessary medications. Complete avoidance of medications or cessation of breast-feeding is often unnecessary. Although there are drugs that can be harmful to nursing infants, breast-milk concentrations of most drugs are insufficient to cause any harm.

Conclusions:

Having objective and reliable information on medications enables pharmacists, pharmacy technicians, other healthcare providers, and mothers to make educated decisions regarding drug therapy and breast-feeding.

Antidepressants, anxiolytics, and hypnotics in pregnancy and lactation

AIMS

Untreated perinatal depression and anxiety disorders are known to have significant negative impact on both maternal and fetal health. Dilemmas still remain regarding the use and safety of psychotropics in pregnant and lactating women suffering from perinatal depression and anxiety disorders. The aim of the current paper was to review the existing evidence base on the exposure and consequences of antidepressants, anxiolytics, and hypnotics in women during pregnancy and lactation and to make recommendations for clinical decision making in management of these cases.

MATERIALS AND METHODS

We undertook a bibliographic search of Medline/PubMed (1972 through 2014), Science Direct (1972 through 2014), Archives of Indian Journal of Psychiatry databases was done. References of retrieved articles, reference books, and dedicated websites were also checked.

RESULTS AND CONCLUSIONS

The existing evidence base is extensive in studying multiple outcomes of the antidepressant or anxiolytic exposure in neonates, and some of the findings appear conflicting. Selective serotonin reuptake inhibitors are the most researched antidepressants in pregnancy and lactation. The available literature is criticized mostly on the lack of rigorous well designed controlled studies as well as lacunae in the methodologies, interpretation of statistical information, knowledge transfer, and translation of information. Research in this area in the Indian context is strikingly scarce. Appropriate risk-benefit analysis of untreated mental illness versus medication exposure, tailor-made to each patient's past response and preference within in the context of the available evidence should guide clinical decision making.

Serotonin reuptake inhibitors and breastfeeding: a systematic review

OBJECTIVE

The postnatal period represents a critical phase for mothers because of physiological hormonal changes, the increase of emotional reactions and a greater susceptibility for the onset/recrudescence of psychiatric disorders. Despite the evidence of an increasing utilization of antidepressant drugs during breastfeeding, there is still few reliable information on the neonatal safety of the selective serotonin reuptake inhibitors (SSRIs) and selective noradrenergic reuptake inhibitors (SNRIs) [serotonin reuptake inhibitors (SRIs)] in nursing mothers. The aim of this study is to provide a systematic review on the neonatal safety profile of these drugs during breastfeeding, also assessing the limits of available tools.

METHODS

MEDLINE and PubMed databases were searched without any language restrictions by using the following set of keywords: ((SSRIs OR selective serotonin inhibitor reuptake OR SNRIs OR selective serotonin noradrenaline inhibitor reuptake) AND (breastfeeding OR lactation OR breast milk)). A separate search was also performed for each SSRIs (paroxetine, fluvoxamine, fluoxetine, sertraline, citalopram and escitalopram) and SNRIs (venlafaxine and duloxetine).

RESULTS

Sertraline and paroxetine show a better neonatal safety profile during breastfeeding as compared with other SRIs. Less data are available for fluvoxamine, escitalopram and duloxetine. Few studies followed up infants breastfeed for assessing the neurodevelopmental outcomes.

CONCLUSIONS

Literature review clearly indicates paroxetine and sertraline as the drugs that should be preferred as first line choice in nursing women who need an antidepressant treatment.

Treatment of depression associated with the menstrual cycle: premenstrual dysphoria, postpartum depression, and the perimenopause

Several forms of depression are unique to women because of their apparent association with changes in gonadal hormones, which in turn modulate neuroregulatory systems associated with mood and behavior. This review examines the evaluation and treatment of depression that occurs premenstrually, postpartum, or in the perimenopause on the basis of current literature. The serotonergic antidepressants consistently show efficacy for severe premenstrual syndromes (PMSs) and premenstrual dysphoric disorder (PMDD), and are the first-line treatment for these disorders. The use of antidepressants for postpartum depression is compromised by concerns for effects in the infants of breast-feeding mothers, but increasing evidence suggests the relative safety of the antidepressant medications, and the risk calculation should be made on an individual basis. Estradiol may be effective for postpartum depression and for moderate-to-severe major depression in the perimenopause. In spite of its frequent use, progesterone is not effective for the mood and behavioral symptoms of PMS/PMDD, postpartum depression, or perimenopausal depressive symptoms.

SSRIs during breastfeeding: spotlight on milk-to-plasma ratio

OBJECTIVE

To investigate the usefulness of the milk-to-plasma (M/P) ratio for assessing the risks for the breastfed infant associated with the maternal use of SSRIs.

DATA SOURCES

Medline, Toxnet, Embase, Current Contents, and PsycInfo indexed articles from 1980 to September 2006.

STUDY SELECTION AND DATA EXTRACTION

All studies reporting the M/P ratio in mothers taking SSRIs while breastfeeding or studies which such an information could be calculated from data reported in the article.

DATA SYNTHESIS

Higher M/P ratios were rarely associated with a clinically significant impact on the babies during the early phases of breastfeeding.

CONCLUSIONS

So far no evidence-based information seems to support the hypothesis that SSRIs characterized by a M/P ratio <1.0 should be preferred. Hence, physicians should consider different parameters when attempting to choose the safest SSRI for the breastfeeding woman. These parameters might be represented by the number of well-documented published adverse event reports and the tendency of each SSRI of inducing in the infants serum concentrations that are elevated above 10% of average maternal serum levels. In any case, if the mother wishes to breastfeed her infant while taking a SSRI, the baby should be closely monitored in order to promptly detect any iatrogenic event.

Use of contemporary antidepressants during breastfeeding: a proposal for a specific safety index

Despite the well known severe repercussions of maternal depression on infants' well being, women are often reluctant to seek pharmacological treatment for postnatal depression. The fear of adverse events for the suckling infant plays an important role in such maternal considerations. However, the pharmacological approach to mood disorders at postpartum onset often represents one of the most realistic options in a number of clinical conditions. Therefore, the necessity exists to establish the safety of antidepressant treatment in the breastfed infant. For this reason, the aim of this article is to propose a specific safety index that assesses the frequency and degree of severity of adverse events in infants associated with maternal treatment with second-generation antidepressants during puerperium. The index is derived from a simple formula that uses the number of reports of adverse events in infants exposed to antidepressants as the numerator and the combined total of reports of healthy outcomes and reports of adverse events as the denominator. The sum is then multiplied by 100. A value of < or =2 indicates that the drug should be relatively safe for use during breastfeeding, a value of 2.1-10 indicates that the drug should be used with great caution and a value >10 indicates that the drug should be contraindicated in breastfeeding mothers. In addition to the figure created by this calculation, each drug will also be assigned a letter or the combination of a letter and a subscripted number to symbolise, respectively, the type and clinical management of the most serious recorded event. At this early developmental stage of the index, a complete classification of contemporary antidepressants regarding their safety in infants nursed to the breast is unfeasible. Indeed, because of the lack of suitable published data, so far the index has been limited to the evaluation of four antidepressants. In accordance with the index classification for these four antidepressants, sertraline and paroxetine should be considered as first-line medications in women who need to start antidepressant treatment during the postpartum period and wish to continue breastfeeding. The utilisation of fluoxetine and citalopram seems conversely to be associated with a relatively higher risk of adverse events (with a low degree of severity, however). For the other newer antidepressant drugs, the index is still of no assistance to the patient or physician in deciding on the safety of their use in lactation.

Broad range analysis of endocrine disruptors and pharmaceuticals using gas chromatography and liquid chromatography tandem mass spectrometry

Endocrine disrupting compounds (EDCs) and pharmaceuticals and personal care products (PPCPs) have been globally detected in impacted natural waters. The detection of trace quantities of EDCs and PPCPs in the environment is of great concern since some of these compounds have known physiological responses at low concentrations. EDCs can have a wide range of polarities, acidic and basic moieties, and exist in trace quantities, which often requires numerous complex extractions, large sample collection volumes, and multiple instrumental analyses. A comprehensive method has been developed allowing for the analysis of 58 potential EDCs in various water matrices using a single solid-phase extraction (SPE) of a 1L sample with subsequent analyses using both gas chromatography and liquid chromatography, each coupled with tandem mass spectrometry (GC-MS/MS and LC-MS/MS). Instrument detection limits ranged between 0.12-7.5 pg with corresponding method reporting limits of 1-10 ng l(-1) in water. Recoveries for most compounds were between 50% and 112% with good reproducibility (RSD 6-22%).

The Use of Tricyclic Antidepressants and Selective Serotonin Reuptake Inhibitors in Women Who Are Breastfeeding

Postpartum depression is a well-recognized psychiatric condition that has gained increased attention over the past decade due to several nationally publicized tragedies. Medical management of this condition in women who are breastfeeding provides a unique challenge to health care professionals who may seek to maintain a fine balance between limiting the infant's exposure to hormone-altering drugs and maintaining the benefits of breastfeeding. No controlled trials have examined antidepressant therapy in nursing women; however, numerous case reports and case series have been published. Relatively few serious adverse effects have been reported. Although tricyclic antidepressants have been the treatment of choice in the past, selective serotonin reuptake inhibitors are gaining popularity due to their superior safety profiles. Of all the agents reviewed in the literature, sertraline was the most prescribed, and no adverse effects were reported. Therefore, this agent would be a good first choice for treatment-naive women. For treatment of postpartum depression in women with a history of successfully treated depression, the most practical approach may be to continue therapy with the previously effective agent. Treatment should be maintained at the lowest effective dosage to minimize infant exposure. Both mother and child should be closely monitored; in addition, collaboration between the prescribing physician and the child's pediatrician is essential.

A light in the fog: caring for women with postpartum depression

It is estimated that at least 1 in 10 women will experience postpartum depression, yet systematic screening for it in clinical practice is too often neglected. The foggy unreality of this affective disorder leads women to believe they are losing their minds, and their efforts to find help can be elusive. Women with postpartum depression who go undetected and untreated are at risk for immediate harm and potential lifelong sequelae for themselves and their families, and especially for their children. This article provides 1) an understanding of the woman's experience of postpartum depression, 2) a review of two instruments, developed through a focused program of research to screen for the disorder, 3) triage in clinical practice, and 4) an overview of the three dimensions of treatment: psychopharmacology, psychotherapy, and psychosocial care. Practical guidance and client information are provided to assist midwives and primary care providers to incorporate systematic screening into clinical practice, to identify effective interdisciplinary treatment teams, and to muster family and community resources to help with this commonly hidden childbearing crisis.

Treatment of depression in women: a summary of the expert consensus guidelines

Women constitute two-thirds of patients suffering from common depressive disorders, making the treatment of depression in women a substantial public health concern. However, high-quality, empirical data on depressive disorders specific to women are limited, and there are no comprehensive evidence-based practice guidelines on the best treatments for these illnesses. To bridge the gap between research evidence and key clinical decisions, the authors developed a survey of expert opinion concerning treatment of four depressive conditions specific to women: premenstrual dysphoric disorder, depression in pregnancy, postpartum depression in a mother choosing to breast-feed, and depression related to perimenopause/menopause. The survey asked about 858 treatment options in 117 clinical situations and included a broad range of pharmacological, psychosocial, and alternative medicine approaches. The survey was sent to 40 national experts on women's mental health issues, 36 (90%) of whom completed it. The options, scored using a modified version of the RAND Corporation's 9-point scale for rating appropriateness of medical decisions, were assigned one of three categorical rankings-first line/preferred choice, second line/alternate choice, third line/usually inappropriate-based on the 95% confidence interval of each item's mean rating. The expert panel reached consensus (defined as a non-random distribution of scores by chi-square "goodness-of-fit" test) on 76% of the options, with greater consensus in situations involving severe symptoms. Guideline tables indicating preferred treatment strategies were then developed for key clinical situations. The authors summarize the expert consensus methodology they used and then, for each of the four key areas, review the treatment literature and summarize the experts' recommendations and how they relate to the research findings. For women with severe symptoms in each area we asked about, the first-line recommendation was antidepressant medication combined with other modalities (generally psychotherapy). These recommendations parallel existing guidelines for severe depression in general populations. For initial treatment of milder symptoms in each situation, the panel was less uniform in recommending antidepressants, and either gave equal endorsement to other treatment modalities (e.g., nutritional or psychobehavioral approaches in PMDD; hormone replacement in perimenopause) or preferred psychotherapy over medication (during conception, pregnancy, or lactation). In all milder cases, however, antidepressants were recommended as at least second-line options. Among antidepressants, selective serotonin reuptake inhibitors (SSRIs) were recommended as first-line treatment in all situations. The specific SSRIs that were preferred depended on the particular clinical situation. Tricyclic antidepressants were highly rated alternatives to SSRIs in pregnancy and lactation. In evaluating many of the treatment options, the experts had to extrapolate beyond controlled data in comparing treatment options with each other or in combination. Within the limits of expert opinion and with the expectation that future research data will take precedence, these guidelines provide some direction for addressing common clinical dilemmas in women, and can be used to inform clinicians and educate patients regarding the relative merits of a variety of interventions.
