Abstract
Allergic rhinitis (AR) is the most common allergic disease worldwide and one of the most common chronic diseases in general. Allergic rhinitis is caused by inhalant allergens from outdoor and indoor environments with varying significance of different allergens in global regions. We provide options for the current management for AR including pharmacological treatments and nonpharmacological options and allergen immunotherapy (AIT). A literature review has been conducted in Medline, Pubmed, as well as the national and international study (ClinicalTrials.gov) and guideline registers and the Cochrane Library. Human studies published on the topic in the period up to and including November 2023 were taken into account. Allergen avoidance measures, pharmacotherapy, and AIT are the cornerstones of AR treatment. Nonpharmacological measures and behavioral recommendations should be adequately added. Tools of precision medicine are already playing a significant role and will be part of the diagnostic and therapeutic standard in the future. Patients benefit most in a network of different pharmacological and nonpharmacological treatment measures including AIT. Application of precision medicine tools for diagnosis and treatment will improve standards of care.

Abstract
A nanocomposite electrode of graphene (Gr) and zinc oxide (ZnO) nanoparticles was fabricated to study the electrochemical oxidation behavior of an anti-inflammatory drug, i.e., cetirizine (CET). The voltametric response of CET for bare CPE, Gr/CPE, ZnO/CPE, and the ZnO-Gr nanocomposite electrode was studied. The modifier materials were characterized using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and X-ray powder diffraction (XRD) to comprehend the surface morphology of the utilized modifiers. The influence of pH, scan rate, and accumulation time on the electrooxidation of CET was examined. It was found that the electrochemical oxidation of CET was diffusion-controlled, in which two protons and two electrons participated. The detection limit was found to be 2.8 × 10−8 M in a linearity range of 0.05–4.0 µM. Study of excipients was also performed, and it was found that they had negligible interference with the peak potential of CET. The validation and utility of the fabricated nanocomposite sensor material were examined by analyzing clinical and biological samples. Stability testing of the nanocomposite electrode was conducted to assess the reproducibility, determining that the developed biosensor has good stability and high efficiency in producing reproducible results.

Abstract
Pregnancy is a unique physiologic state whose characteristics often predispose women to new-onset sleep disturbances or exacerbations of preexisting sleep disorders. Pregnancy-related factors that can disrupt sleep include heartburn, nocturnal oxytocin secretion, nocturia, and fetal movement. Sleep disorders in pregnancy include insomnia (primary and secondary), restless legs syndrome, and narcolepsy.

Abstract
Chronic urticaria (CU) is a mast cell-driven chronic inflammatory disease with a female predominance. Since CU affects mostly females in reproductive age, pregnancy is an important aspect to consider in the context of this disease. Sex hormones affect mast cell (MC) biology, and the hormonal changes that come with pregnancy can modulate the course of chronic inflammatory conditions, and they often do. Also, pregnancy-associated changes in the immune system, including local adaptation of innate and adaptive immune responses and skewing of adaptive immunity toward a Th2/Treg profile have been linked to changes in the course of inflammatory diseases. As of now, little is known about the effects of pregnancy on CU and the outcomes of pregnancy in CU patients. Also, there are no real-life studies to show the safety of urticaria medications during pregnancy. The recent PREG-CU study provided the first insights on this and showed that CU improves during pregnancy in half of the patients, whereas it worsens in one-third; and two of five CU patients experience flare-ups of their CU during pregnancy. The international EAACI/GA2LEN/EuroGuiDerm/APAAACI guideline for urticaria recommends adopting the same management strategy in pregnant and lactating CU patients; starting treatment with standard doses of second-generation (non-sedative) H1 antihistamines, to increase the dose up to 4-folds in case of no response, and to add omalizumab in antihistamine-refractory patients; but also emphasizes the lack of evidence-based information on the safety and efficacy of urticaria treatments during pregnancy. The PREG-CU study assessed treatments and their outcomes during pregnancy. Here, we review the reported effects of sex hormones and pregnancy-specific immunological changes on urticaria, we discuss the impact of pregnancy on urticaria, and we provide information and guidance on the management of urticaria during pregnancy and lactation.

Abstract
PURPOSE To investigate whether exposure to antazoline-naphazoline eye drops in the first trimester of pregnancy was associated with an increased risk of malformations in humans. METHODS All women giving live birth between 1997 and 2011 in Denmark were included in this nationwide cohort study. All women redeeming at least one prescription of antazoline-naphazoline eye drops during the first 84 days of pregnancy were identified. Logistic regression was used to estimate the odds ratios of malformations among exposed offspring compared to non-exposed offspring. RESULTS We identified 977 706 births between 1997 and 2011. A total of 3061 women (0.32%) were exposed to antazoline-naphazoline eye drops in the first trimester of pregnancy. The rate of congenital malformations was 3.0% (n = 93) in exposed offspring and 3.5% (n = 33 594) in unexposed offspring. First-trimester exposure to antazoline-naphazoline was not associated with major congenital malformations overall (odds ratio: 0.88, 95% confidence interval: 0.71-1.09) or with any specific major malformation. The number of redeemed prescriptions was unchanged during all trimesters of pregnancy as compared to before and after pregnancy (p < 0.05). CONCLUSION Exposure to antazoline-naphazoline eye drops in the first trimester of pregnancy appears not to be associated with increased teratogenic risk.

Abstract
Risks, benefits, alternatives, and appropriateness of psychotropic medications, including risks of no treatment, are discussed for antidepressants, mood-stabilizing medications, anxiolytic/sedative hypnotic medications, stimulants, and medication-assisted treatment of substance use disorders. Early screening, diagnosis, and intervention prior to and/or during pregnancy often reduce morbidity and mortality of mental health disorders for mothers and infants.

Abstract
Pregnancy often predisposes women to new-onset sleep disturbances, as well as exacerbations of preexisting sleep disorders. The goals of treating perinatal sleep disorders include the promotion of restorative sleep and the benefits it brings to both mother and fetus. The prescribing of any sleep aid in pregnancy must include consideration of the risks and benefits for both the patient and her fetus. Although data on the perinatal use of sleep aids is limited, there may be effects on fetal development, timing and duration of delivery, and postnatal outcomes.

Abstract
Background Allergic rhinitis (AR) affecting ∼20–30% of women in childbearing age can be considered one of the most common group of medical conditions that complicate pregnancy. AR with symptoms of nasal obstruction, sneezing, and itching may require pharmacotherapy. However, there are concerns regarding the safety of different available agents that can be used during pregnancy with respect to both maternal and fetal well being. Conclusions The best first-line approach in the management of AR is avoidance of allergens. If environmental modification is ineffective, then the pharmacologic agents should be chosen. For symptoms of rhinorrhea, sneezing, or itching, intranasal cromolyn, with its excellent safety profile, should be considered as first-line therapy. If cromolyn is ineffective or poorly tolerated, first-generation (e.g., chlorpheniramine and tripelennamine) and second generation (e.g., cetirizine and loratadine) antihistamines can be given. Intranasal steroids (e.g., beclomethasone dipropionate, and budesonide) can be added to first-line therapy especially for severe nasal obstruction. There are no epidemiological studies with newer intranasal steroids (e.g., flunisolide, triamcinolone acetonide, fluticasone propionate, and mometasone furoate) during the first trimester of pregnancy. Immunotherapy has not proven to be teratogenic and is clinically useful in improving symptoms. Oral and topical decongestants can be considered as second-line therapy, for short-term relief, when no safer alternative is available.

Abstract
INTRODUCTION H1 antihistamines are used for the treatment of nausea and vomiting during pregnancy as well as the symptomatic relief of asthma, urticaria, allergy, and the common cold. Although they are overall felt to be safe during pregnancy, recently several studies have challenged this assumption, as millions of women are exposed to them in the first trimester. METHODS Following the guidelines of PRISMA, a systematic review was performed to retrieve all published articles involving H1-antihistamine exposure during pregnancy. Electronic databases including PubMed and EMBASE were searched for possibly relevant articles published in any language up to December 2015. RESULTS After removing duplicate publications, and excluding animal studies and studies on drug effectiveness, 342 articles were reviewed in detail and 37 studies fulfilled the inclusion criteria for the meta-analysis. In cohort studies, the risk of major malformation in the offspring of women exposed to H1 antihistamines was not higher than that of the control population (OR 1.07; 95% CI 0.98-1.16). The Q-statistic for heterogeneity of effects was not significant (p > 0.05, I 2 < 25%) and there was no evidence of publication bias. Similar results were achieved with case-control studies (OR 1.05; 95% CI 0.90-1.23). Similarly, H1 antihistamines were not associated with more spontaneous abortions (OR 1.00; 95% CI 0.83-1.20), prematurity (OR 0.96; 95% CI 0.76-1.20), stillbirth (OR 1.23; 95% CI 0.48-3.18) or low birth weight (OR 1.20; 95% CI 0.63-2.29). CONCLUSIONS Based on our meta-analyses, which included a large number of studies, H1 antihistamines are not associated with an increased risk of major malformation or other adverse fetal outcomes. This study provides important information to both pregnant women and their healthcare providers regarding the safety and risk of H1 antihistamine use during this sensitive time.

Abstract
Allergic diseases are common in women of childbearing age. Both asthma and atopic conditions may worsen, improve or remain the same during pregnancy. Primary care physicians commonly encounter women receiving multiple medications for pre-existing atopic conditions, who then become pregnant and require medication changes to avoid potential fetal injury or congenital malformations. Each medication should be evaluated; intranasal and inhaled steroids are relatively safe to continue during pregnancy (budesonide is the drug of choice), second-generation antihistamines of choice are cetirizine and loratadine, leukotriene receptor antagonists are safe, sparing use of oral decongestants during the first trimester and omalizumab may be used for both uncontrolled asthma and for antihistamine-resistant urticaria. Medications to avoid during pregnancy include intranasal antihistamines, first-generation antihistamines, mycophenolate mofetil, methotrexate, cyclosporine, azathioprine and zilueton. Common allergic diseases may develop de novo during pregnancy, such as anaphylaxis.

Abstract
Objective To present current guidelines regarding treatment of mastocytosis in pregnancy on the example of observed patients. Design Case control national study. Setting Polish Center of the European Competence Network on Mastocytosis (ECNM). Population or Sample 23 singleton spontaneous pregnancies in 17 women diagnosed with mastocytosis in years 1999–2014, before becoming pregnant. Methods Prospective analysis outcomes of pregnancies and deliveries. Main Outcome Measures Survey developed in cooperation with the Spanish Instituto de Estudios de Mastocitosis de Castilla-La Mancha (CLMast), Hospital Virgen del Valle, Toledo, Red Espańola de Mastocitosis (REMA), Spain. Results All 23 pregnancies resulted from natural conception. Obstetrical complications recorded in the first trimester included spontaneous miscarriage (5 pregnancies). Four patients delivered preterm, including one delivery due to preeclampsia at 26 weeks which resulted with neonate death due to extreme prematurity. Five women delivered via cesarean: four due to obstetrical indications and one due to mastocytosis, during which no anesthesia related complications were recorded. Of patients delivering vaginally, two received extradural anesthesia, three required oxytocin infusion due to uterine hypotonia. No labor complications were recorded. In one woman with pregnancy-induced hypertension, early puerperium was complicated by the presence of persistent arterial hypertension. One neonate was born with the signs of cutaneous mastocytosis. Another neonate was diagnosed with Patau syndrome. Four women were treated for mastocytosis prior to conception and continued therapy after becoming pregnant. One patient was put on medications in the first trimester due to worsening of her symptoms. Pregnancy exerted only a slight effect on the intensity and frequency of mastocytosis-related symptoms observed. Worsening of the disease-related symptoms was documented in only four patients (23%). None of the patients showed the signs of anaphylaxis, either before becoming pregnant, or during pregnancy and puerperium. Conclusions There is no contraindication to pregnancy when mastocystosis-related pathologies are under appropriate medical control.

Abstract
This guidance for the management of patients with chronic urticaria and angioedema has been prepared by the Standards of Care Committee of the British Society for Allergy and Clinical Immunology (BSACI). The guideline is based on evidence as well as on expert opinion and is aimed at both adult physicians and paediatricians practising in allergy. The recommendations are evidence graded. During the development of these guidelines, all BSACI members were included in the consultation process using a Web-based system. Their comments and suggestions were carefully considered by the Standards of Care Committee. Where evidence was lacking, a consensus was reached by the experts on the committee. Included in this management guideline are clinical classification, aetiology, diagnosis, investigations, treatment guidance with special sections on children with urticaria and the use of antihistamines in women who are pregnant or breastfeeding. Finally, we have made recommendations for potential areas of future research.

INTRODUCTION Approximately 10 - 15% of women reportedly take an antihistamine during pregnancy for the relief of nausea and vomiting, allergy and asthma symptoms, or indigestion. Antihistamines include histamine H1-receptor and H2-receptor antagonists. AREAS COVERED This is a systematic evaluation of the peer-reviewed epidemiologic literature published through February 2014 on the association between prenatal exposure to antihistamines and birth defects. Papers addressing histamine H1- or H2-receptor antagonists are included. Papers addressing pyridoxine plus doxylamine (Bendectin in the United States, Debendox in the United Kingdom, Diclectin in Canada, Lenotan and Merbental in other countries) prior to the year 2001 were excluded post hoc because of several previously published meta-analyses and commentaries on this medication. EXPERT OPINION The literature on the safety of antihistamine use during pregnancy with respect to birth defects is generally reassuring though the positive findings from a few large studies warrant corroboration in other populations. The findings in the literature are considered in light of three critical methodological issues: i) selection of appropriate study population; ii) ascertainment of antihistamine exposures; and iii) ascertainment of birth defect outcomes. Selected antihistamines have been very well studied (e.g., loratadine); others, especially H2-receptor antagonists, require additional study before an assessment of safety with respect to birth defect risk could be made.

Abstract
BACKGROUND Several studies have reported an association between use of specific antihistamines in early pregnancy and certain specific birth defects. OBJECTIVE To test 16 previously hypothesized associations between specific antihistamines and specific birth defects, and to identify possible new associations. METHODS We used 1998-2010 data from the Slone Epidemiology Center Birth Defects Study, a multicenter case-control surveillance program of birth defects in North America. Mothers were interviewed within 6 months of delivery about demographic, reproductive, medical, and behavioral factors, and details on the use of prescription and nonprescription medications. We compared first trimester exposure to specific antihistamines between 13,213 infants with specific malformations and 6982 nonmalformed controls by using conditional logistic regression to estimate odds ratios and 95% confidence intervals (CIs), with adjustment for potential confounders, including indication for use. RESULTS Overall, 13.7% of controls were exposed to antihistamines during the first trimester. The most commonly used medications were diphenhydramine (4.2%), loratadine (3.1%), doxylamine (1.9%), and chlorpheniramine (1.7%). When estimates were stable, none supported the previously hypothesized associations. Among more than 100 exploratory comparisons of other specific antihistamine-defect pairs, 14 had odds ratios ≥1.5, of which 6 had 95% CI bounds excluding 1.0 before but not after adjustment for multiple comparisons. CONCLUSION Our findings do not provide meaningful support for previously posited associations between antihistamines and major congenital anomalies; at the same time, we identified associations that had not been previously suggested. We suspect that previous associations may be chance findings in the context of multiple comparisons, a situation that may also apply to our new findings.

Abstract
Antihistamines have long been a mainstay in the therapy for allergic rhinitis. Many different oral antihistamines are available for use, and they are classified as first generation or second generation based on their pharmacologic properties and side-effect profiles. The recent introduction of intranasal antihistamines has further expanded the role of antihistamines in the treatment of allergic rhinitis. Certain patient populations, such as children and pregnant or lactating women, require special consideration regarding antihistamine choice and dosing as part of rhinitis therapy.

Abstract
Pharmacologic therapy of a pregnant patient requires particular care in selecting the active substances to be used, their dosage and administration. The teratogenic risk and the therapeutic benefit must be carefully weighed for the mother and possibly also for the child, and attention paid to the special precautions and documentation obligations of off-label applications. This article addresses the general aspects of benefit-risk evaluation, provides an opinion on the teratogenic potency of dermatologically relevant medications, formulates recommendations for frequent general dermatological indications and lists additional possible information sources for special case constellations.

Abstract
Chronic rhinosinusitis, including nasal polyps, is an inflammatory disease of the nose and sinuses. The medical treatment, mainly topical intranasal and oral corticosteroids, constitutes its first line of therapy. Long-term treatment with corticosteroid nasal spray reduces inflammation and nasal polyp size, and improves nasal symptoms such as nasal blockage, rhinorrea, and the loss of smell. Corticosteroid intranasal drops may be used when intranasal spray fails to demonstrate efficacy. Short courses of oral steroids are recommended in severe chronic rhinosinusitis with nasal polyps or when a rapid symptomatic improvement is needed. Endoscopic sinus surgery is only recommended when the medical treatment fails. Intranasal corticosteroids should be continued postoperatively. When using intranasal corticosteroids, care should be taken in selected populations such as children, pregnant women, and elderly patients; especially in those patients with comorbid conditions such as asthma, in which the overall steroid intake can be high due to the administration of both intranasal and inhaled corticosteroids.

Abstract
INTRODUCTION Many pregnant women are asthmatics and maternal asthma is a source of questions and complications concerning both the progress of the pregnancy itself and the impact on the foetus. In this situation good asthma control is essential as the disease can deteriorate with acute exacerbations, possibly precipitated by reduction or even withdrawal of treatment on account of fear of teratogenicity. BACKGROUND Even though asthma treatments are not totally harmless during pregnancy, their use has been validated by several studies and guidelines. To help clinicians, we undertake here a review of the complications induced by maternal asthma and its medications, and then suggest management guidelines according to the most recent publications. CONCLUSIONS The risks and benefits of asthma treatments should be explained in a real partnership between the patient and her general practitioner and specialists (obstetrician, chest physician or allergist). In order to reduce complications to both mother and child, perfect control of asthma is required and inhaled steroids remain the treatment of choice for partially or uncontrolled asthma in the pregnant woman.

Abstract
Allergic rhinitis is a high-prevalence disease that significantly impairs the quality of life. Its pathogenesis is quite well understood, and involves numerous cells, cytokines and mediators, which result in an inflammatory process. The triggering IgE-mediated reaction does not differ between men and women, but in females some aspects, related mainly to the hormonal frame, must be taken into account. In fact, cyclic hormonal changes can affect the severity of rhinitis, as can pregnancy, which may result in a particular form of 'pregnancy rhinitis'. The most important and challenging aspect is the management of allergic rhinitis in pregnancy, which require a careful evaluation of the risk:benefit ratio. This review will examine the aforementioned aspects, with particular regard to the pharmacotherapy of rhinitis in pregnancy.

Abstract
This guidance for the management of patients with chronic urticaria and angio-oedema has been prepared by the Standards of Care Committee (SOCC) of the British Society for Allergy and Clinical Immunology (BSACI). The guideline is based on evidence as well as on expert opinion and is aimed at both adult physicians and paediatricians practising in allergy. The recommendations are evidence graded. During the development of these guidelines, all BSACI members were included in the consultation process using a web-based system. Their comments and suggestions were carefully considered by the SOCC. Where evidence was lacking a consensus was reached by the experts on the committee. Included in this guideline are clinical classification, aetiology, diagnosis, investigations, treatment guidance with special sections on children with urticaria, and the use of antihistamines in women who are pregnant or breastfeeding. Finally, we have made recommendations for potential areas of future research.

Abstract
BACKGROUND Women and their health care providers have few reliable sources of information regarding the safety of exposures in pregnancy and lactation. Evidence-based information on these topics is provided by Teratology Information Services (TIS). Access to TIS, however, is limited in many regions, and many services have difficulty maintaining ongoing funding. The objective of this review is to highlight published reports of the effectiveness of TIS in improving maternal and neonatal health. METHODS A search of the Pub Med and Econ Lit databases was performed with no date restriction, using the search terms teratology, information, counseling, pregnancy, effectiveness, birth defects. RESULTS Information disseminated from TIS has been shown to prevent congenital malformations, unnecessary pregnancy terminations, and occupational risks. TIS support optimal nutritional supplementation in pregnancy and optimal drug therapy in pregnancy and breast-feeding. In addition, they correct misperceptions of risk and facilitate knowledge transfer and translation. TIS have the potential to provide health care cost savings. CONCLUSIONS TIS are vital services in supporting optimal maternal and neonatal health. A formal economic evaluation of TIS is required in order to inform resource allocation decision-making and continued funding of these services.

Abstract
Numerous pregnant women suffer from allergic rhinitis, and particular attention is required when prescribing drugs to these patients. In addition, physiologic changes associated with pregnancy could affect the upper airways. Evidence-based guidelines on the management of allergic rhinitis have been published. Medication can be prescribed during pregnancy when the apparent benefit of the drug is greater than the apparent risk. Usually, there is at least one "safe" drug from each major class used to control symptoms. All glucocorticosteroids are teratogenic in animals but, when the indication is clear (for diseases possibly associated, such as severe asthma exacerbation), the benefit of the drug is far greater than the risk. Inhaled glucocorticosteroids (eg, beclomethasone or budesonide) have not been incriminated as teratogens in humans and are used by pregnant women who have asthma. A few H1-antihistamines can safely be used as well. Most oral decongestants (except pseudoephedrine) are teratogenic in animals. There are no such data available for intranasal decongestants. Finally, pregnancy is not considered to be a contraindication for the continuation of immunotherapy.

Abstract
Given the unique nature of pregnancy with respect to obtaining safety data regarding medication exposures, developing comprehensive information on the wide variety of medications that might be of clinical benefit during pregnancy is a challenging and on-going task. For many of the most commonly used asthma and allergy medications that were covered in this article, there is at least limited human data are available. Even for relatively well-studied medications, there are many unanswered questions, and few studies exist that are large enough to rule out at least a doubling of risk for specific outcomes, particularly congenital anomalies. This challenge becomes even more daunting when evaluating risks of individual products is considered the optimal goal, as opposed to "lumping" all medication exposures within a class. All of these issues call for more human pregnancy data that are collected more efficiently so that the answers that clinicians and pregnant women need are available more readily. In the meantime, health care providers and pregnant women must work with the information that is available to evaluate the risks and benefits of a particular medication and alternative choices for treatment of asthma or allergy during pregnancy, while considering the potential for adverse effects if the woman with severe or uncontrolled asthma is under-treated. To assist in making a risk/benefit assessment, the clinician can draw on existing resources that provide systematic periodic review of new data on medications in pregnancy as it becomes available, and synthesize the entire body of data on a particular drug into concise summary statements. Two such resources are TERIS (TeratogenInformation System) [38] and Reprotox [39]; both on-line services are managed by experts in the field of teratology. An additional resource for clinicians and pregnant women is the Organization of Teratology Information Specialists [40], a network of risk-assessment counselors in the United States and Canada who specialize in research and the communication of risks that are associated with exposures in pregnancy.

Abstract
Physicians are generally reluctant to prescribe dermatologic drugs to pregnant or nursing women because treatment is often elective and can be harmful to the patient, her fetus, or nursing infant; concerns for potential litigation also give pause. Yet, some effective dermatologic drugs have been determined to be safe during pregnancy and lactation. Of great practicality is an easily accessed reference guide that condenses information on such drugs into a set of tables that list pregnancy and teratogenicity ratings. Indications and contraindications are ordered in relation to the phases and trimesters of pregnancy. A discussion of the necessity of considering stages of childbearing in choosing drug therapies introduces the tables. A summary list of cautions spells out the steps physicians should take in treating women of childbearing age.

Abstract
Allergic rhinitis is the most common allergic disease. Pharmacological interventions are often not used in pregnancy because of alarming information in drug labels and patient information, even when evidence for safety exists.Low-risk therapies could include immunotherapy, intranasal sodium cromoglycate (cromolyn sodium), beclometasone, budesonide and first-generation antihistamines. In a meta-analysis examining the safety of first-generation antihistamines in pregnancy, 200 000 first trimester exposures failed to show increased teratogenic risk. Loratadine is the most studied second-generation antihistamine (with a total patient cohort of 2147 women who were exposed) and does not appear to increase the risk of major congenital malformations; however, it has not been as well studied as the earlier antihistamines. Since desloratadine is the principal metabolite of loratadine, it can be assumed that a similar safety profile would fit for desloratadine as was described for loratadine although no direct human studies have been done. Decongestants have not been conclusively proven to affect the fetal outcome and may be used for short-term relief when no other safer alternatives are available. Intranasal corticosteroids have not been associated with an increase in congenital malformations in humans. Based on efficacy and the fact that there would be little systemic absorption, they can be considered a first-line treatment over oral antihistamines, decongestants and mast cell stabilisers; however, the number of controlled trials in pregnancy is limited. Intranasal corticosteroids are associated with minimal systemic effects in adults and are the most effective therapy for allergic rhinitis. Benefit-risk considerations must, therefore, be done but favour their first-line use during pregnancy. Because fetal safety is paramount, recommendations should be based both on the safety of the drugs during pregnancy and the comparative efficacy of the agent in the treatment of the underlying condition. This review exemplifies the fact that there are many safe treatment options for the clinician when dealing with allergic rhinitis during pregnancy.

Abstract
Antihistamines are useful medications for the treatment of a variety of allergic disorders. Second-generation antihistamines avidly and selectively bind to peripheral histamine H1 receptors and, consequently, provide gratifying relief of histamine-mediated symptoms in a majority of atopic patients. This tight receptor specificity additionally leads to few effects on other neuronal or hormonal systems, with the result that adverse effects associated with these medications, with the exception of noticeable sedation in about 10% of cetirizine-treated patients, resemble those of placebo overall. Similarly, serious adverse drug reactions and interactions are uncommon with these medicines. Therapeutic interchange to one of the available second-generation antihistamines is a reasonable approach to limiting an institutional formulary, and adoption of such a policy has proven capable of creating substantial cost savings. Differences in overall efficacy and safety between available second-generation antihistamines, when administered in equivalent dosages, are not large. However, among the antihistamines presently available, fexofenadine may offer the best overall balance of effectiveness and safety, and this agent is an appropriate selection for initial or switch therapy for most patients with mild or moderate allergic symptoms. Cetirizine is the most potent antihistamine available and has been subjected to more clinical study than any other. This agent is appropriate for patients proven unresponsive to other antihistamines and for those with the most severe symptoms who might benefit from antihistamine treatment of the highest potency that can be dose-titrated up to maximal intensity.

Abstract
UNLABELLED Cetirizine is a selective, second-generation histamine H1 receptor antagonist, with a rapid onset, a long duration of activity and low potential for interaction with drugs metabolised by the hepatic cytochrome P450 system. Cetirizine was generally more effective than other H1 receptor antagonists at inhibiting histamine-induced wheal and flare responses. Cetirizine is an effective and well tolerated agent for the treatment of symptoms of seasonal allergic rhinitis (SAR), perennial allergic rhinitis (PAR) and chronic idiopathic urticaria (CIU) in adult, adolescent and paediatric patients. In adults with these allergic disorders, cetirizine was as effective as conventional dosages of ebastine (SAR, PAR, CIU), fexofenadine (SAR), loratadine (SAR, CIU) or mizolastine (SAR). This agent was significantly more effective, and with a more rapid onset of action, than loratadine in 2-day studies in environmental exposure units (SAR). In paediatric patients, cetirizine was as at least as effective as chlorphenamine (chlorpheniramine) [SAR], loratadine (SAR, PAR) and oxatomide (CIU) in the short term, and more effective than oxatomide and ketotifen (PAR) in the long term. Cetirizine was effective in reducing symptoms of allergic asthma in adults and reduced the relative risk of developing asthma in infants with atopic dermatitis sensitised to grass pollen or house dust mite allergens. It had a corticosteroid-sparing effect in infants with severe atopic dermatitis and was effective in ameliorating reactions to mosquito bites in adults. Cetirizine was well tolerated in adults, adolescents and paediatric patients with allergic disorders. In adult, adolescent and paediatric patients aged 2-11 years, the incidence of somnolence with cetirizine was dose related and was generally similar to that with other second-generation H1 receptor antagonists. Although, its sedative effect was greater than that of fexofenadine in some clinical trials and that of loratadine or fexofenadine in a postmarketing surveillance study. In infants aged 6-24 months, the tolerability profile of cetirizine was similar to that of placebo. Cetirizine did not have any adverse effects on cognitive function in adults, or cognitive function, behaviour or achievement of psychomotor milestones in paediatric patients. Cetirizine was not associated with cardiotoxicity. CONCLUSION Cetirizine is well established in the treatment of symptoms of SAR, PAR or CIU. It demonstrated a corticosteroid-sparing effect and reduced the relative risk of developing asthma in sensitised infants with atopic dermatitis. Cetirizine was effective in the treatment of allergic cough and mosquito bites; however, its precise role in these indications has yet to be clearly established. On the basis of its favourable efficacy and tolerability profile and rapid onset of action, cetirizine provides an important option for the treatment of a wide range of allergic disorders.

Abstract
Allergic rhinitis is a frequent problem during pregnancy. In addition, physiological changes associated with pregnancy can affect the upper airways. Evidence-based guidelines on the management of allergic rhinitis have recently been published, the most recent being the Allergic Rhinitis and its Impact on Asthma (ARIA)--World Health Organization consensus. Many pregnant women experience allergic rhinitis and particular attention is required when prescribing drugs to these patients. Medication can be prescribed during pregnancy when the apparent benefit of the drug is greater than the apparent risk. Usually, there is at least one drug from each major class that can be safely utilised to control symptoms. All glucocorticosteroids are teratogenic in animals but, when the indication is clear (for diseases possibly associated, such as severe asthma exacerbation), the benefit of the drug is far greater than the risk. Inhaled glucocorticosteroids (e.g. beclomethasone or budesonide) have not been incriminated as teratogens in humans and are used by pregnant women who have asthma. A few histamine H(1)-receptor antagonists (H(1)-antihistamines) can safely be used as well. Most oral decongestants (except pseudoephedrine) are teratogenic in animals. There are no such data available for intra-nasal decongestants. Finally, pregnancy is not considered as a contraindication for the continuation of allergen specific immunotherapy.

Abstract
Intranasal corticosteroids and intranasal antihistamines are efficacious topical therapies in the treatment of allergic rhinitis. This review addresses their relative roles in the management of this disease, focusing on their safety and tolerability profiles. The intranasal route of administration delivers drug directly to the target organ, thereby minimising the potential for the systemic adverse effects that may be evident with oral therapy. Furthermore, the topical route of delivery enables the use of lower doses of medication. Such therapies, predominantly available as aqueous formulations following the ban of chlorofluorocarbon propellants, have minimal local adverse effects. Intranasal application of therapy can induce sneezing in the hyper-reactive nose, and transient local irritation has been described with certain formulations. Intranasal administration of corticosteroids is associated with minor nose bleeding in a small proportion of recipients. This effect has been attributed to the vasoconstrictor activity of the corticosteroid molecules, and is considered to account for the very rare occurrence of nasal septal perforation. Nasal biopsy studies do not show any detrimental structural effects within the nasal mucosa with long-term administration of intranasal corticosteroids. Much attention has focused on the systemic safety of intranasal application. When administered at standard recommended therapeutic dosage, the intranasal antihistamines do not cause significant sedation or impairment of psychomotor function, effects that would be evident when these agents are administered orally at a therapeutically relevant dosage. The systemic bioavailability of intranasal corticosteroids varies from <1% to up to 40-50% and influences the risk of systemic adverse effects. Because the dose delivered topically is small, this is not a major consideration, and extensive studies have not identified significant effects on the hypothalamic-pituitary-adrenal axis with continued treatment. A small effect on growth has been reported in one study in children receiving a standard dosage over 1 year, however. This has not been found in prospective studies with the intranasal corticosteroids that have low systemic bioavailability and therefore the judicious choice of intranasal formulation, particularly if there is concurrent corticosteroid inhalation for asthma, is prudent. There is no evidence that such considerations are relevant to shorter-term use, such as in intermittent or seasonal disease. Intranasal therapy, which represents a major mode of drug delivery in allergic rhinitis, thus has a very favourable benefit/risk ratio and is the preferred route of administration for corticosteroids in the treatment of this disease, as well as an important option for antihistaminic therapy, particularly if rapid symptom relief is required.

Abstract
Epidemiological studies showed that bronchial asthma is one of the most common diseases which can complicate pregnancy (1-7%). In about 0.05-2% of the cases, asthma occurs as a life-threatening event. In the common medical practice a waiting strategy or, even, the complete refusal for drug therapies are frequently observed. This is justified by the fear of the possible adverse effects of drugs on developing fetus. On the contrary, several studies have demonstrated that severe and uncontrolled asthma may produce serious maternal and fetal complications, such as gestational hypertension and eclampsia, fetal hypoxemia and an increased risk of perinatal death. Therefore, all pregnant women suffering from bronchial asthma should be considered as potentially at high risk of complications and adequately treated. Since asthma is a chronic disease with acute exacerbations, a continuous treatment is mandatory to control symptoms, to prevent acute episodes and to reduce the degree of airway inflammation. The global strategy for asthma management in pregnancy includes five main topics: (1) objective evaluation of maternal/ fetal clinical conditions; (2) avoidance/control of triggering factors; (3) pharmacological treatment; (4) educational support; (5) psychological support. As far as drug therapy is concerned, the International Guidelines and Recommendations suggest that the general strategy does not differ significantly from management outside pregnancy. We herein review and discuss the available data and the criteria for the management of asthma in pregnant patients.

Abstract
Exposures to over-the-counter and herbal products are frequent in pregnant women. Limited information exists on the effects of many of these agents during pregnancy; it is not safe to assume that because these products are available without a prescription that they are without danger to the pregnant woman and her fetus. The basic principles utilized in deciding whether to employ prescription medications such as dose, embryological timing and potential toxic fetal effects also apply to herbal medications and over-the-counter agents. Conventional reasoning indicates that maternal exposure to poorly studied medications should be limited; therefore, many of these agents should be used sparingly or not at all by pregnant women. This chapter includes a review of selected herbal and over-the-counter agents, including those which are considered to be acceptable for use in pregnancy.

Abstract
BACKGROUND Loratadine is a second-generation histamine H(1)-receptor antagonist, used in the treatment of allergic conditions. No prospective controlled trials on loratadine in human pregnancy have been published to date. OBJECTIVE To determine whether the use of loratadine or other antihistamines (OAH) is associated with an increased risk of major anomalies. METHODS Callers who were counseled by the Israeli Teratogen Information Service in regard to loratadine or OAH exposure during pregnancy were prospectively collected and followed up. Pregnancy outcome was compared among three exposure groups: loratadine, OAH, and a control group of patients who were counseled for nonteratogenic exposure, nonteratogenic controls (NTC). The OAH included astemizole, chlorpheniramine, terfenadine, hydroxyzine, promethazine, and dimetindene. RESULTS We followed up 210 pregnancies exposed to loratadine (77.9% in the first trimester) and 267 pregnancies exposed to OAH (64.6% in the first trimester) and compared pregnancy outcome with that of 929 NTC. The rate of congenital anomalies did not differ among the groups [loratadine: 4/175 (2.3%), OAH: 10/247 (4.0%), NTC: 25/844 (3.0%), P =.553, relative risk (RR), 0.77; 95% confidence interval (CI), 0.27 to 2.19, (loratadine vs NTC); RR, 0.56; 95% CI, 0.18 to 1.77, (loratadine vs OAH)]. The rate did not differ between those exposed to antihistamines in the first trimester and the control patients [loratadine: 1/126 (0.8%), OAH: 7/146 (4.8%), NTC: 25/844 (3.0%), P =.152, RR, 0.27; 95% CI, 0.04 to 1.94, (loratadine vs NTC); RR, 0.17; 95% CI, 0.02 to 1.33, (loratadine vs OAH)]. CONCLUSIONS This study on the use of loratadine in human pregnancy suggests that this agent does not represent a major teratogenic risk. The study was powered to find a 3-fold increase in the overall rate of major anomalies.

Abstract
OBJECTIVES To objectively critique recent available data on the proper management of allergy and asthma during pregnancy, with an emphasis on understanding the risk and benefit of medications used during pregnancy for these disorders. DATA SOURCES Data for this article were obtained from a MEDLINE search of literature from 1975 until the present published in English. STUDY SELECTION It was the expert opinion of the author to select and synthesize recently published articles and reviews on this broad subject. RESULTS Asthma is estimated to affect up to 4% of pregnancies, whereas rhinitis complicates up to 20%. The cornerstones of management are environmental avoidance procedures, pharmacologic treatment, and allergen immunotherapy. Pharmaceutical treatment for allergic rhinitis should start with the first-generation antihistamines, chlorpheniramine and tripelennamine. In pregnant women, who cannot tolerate first-generation antihistamines, use of a second-generation agent, either loratadine or cetirizine, should be considered. Though data are lacking, intranasal corticosteroids appear to be safe during pregnancy. For pregnant women with persistent asthma, the use of inhaled cromolyn should be the first-line therapy, followed by inhaled budesonide if symptoms worsen. Other agents such as salmeterol, leukotriene modifiers, and newer inhaled corticosteroids may be considered in women who exhibited a good response to these agents before pregnancy. Immunotherapy is the only disease-modifying treatment for allergic rhinitis and asthma. It can be continued during pregnancy. CONCLUSIONS Understanding the important differences in treatment for the pregnant patient is vital for all physicians caring for these patients. Proper medical management needs to take into consideration possible adverse effects of different agents used in asthma and rhinitis.
