RESUMEN

Sickle cell disease (SCD) is a hereditary haemoglobinopathy which causes multi-organ dysfunction. Pregnancies in SCD are high risk with significant maternal and fetal morbidity and mortality, including vaso-occlusive crises, thrombosis, anaemia, placental insufficiency, fetal growth restriction, preterm birth and medication effects. High level evidence on this topic is lacking. The Australian Sickle Cell Disease Working Group has reviewed international guidelines on this topic and provide an up-to-date and structured approach to the pre-conception, antenatal, birth and post-partum management of these women. Early and comprehensive multidisciplinary care involving experienced clinicians is recommended.

RESUMEN

OBJECTIVES: To examine patterns in the dispensing of category X medications (Therapeutic Goods Administration categorisation system for prescribing medicines in pregnancy) to women aged 15-49 years in Australia during 2008-2021, and patterns of concurrent use of hormonal long-acting reversible contraception (LARC) and other hormonal contraception. STUDY DESIGN: Retrospective cohort study; analysis of 10% random sample of national Pharmaceutical Benefits Scheme dispensing data. PARTICIPANTS, SETTING: Women aged 15-49 years dispensed category X medications, Australia, 1 January 2013 - 31 December 2021. MAIN OUTCOME MEASURES: Incident and prevalent dispensing of category X medications, by medication class, age group, and year; contraceptive overlap (proportions of women dispensed hormonal LARC or other hormonal contraception that overlapped the first dispensing of category X medications), by medication class. RESULTS: Among 15 627 women aged 15-49 years dispensed category X medications during 2013-2021, the prevalence of dispensing increased from 4.6 in 2013 to 8.7 per 1000 women aged 15-49 years in 2021; the largest increase was for the dispensing of dermatological agents, from 3.9 to 7.9 per 1000 women aged 15-49 years. LARC overlap was inferred for 2059 women at the time of first dispensing of category X medications (13.2%); 3441 had been dispensed any type of hormonal contraception (22.1%). The proportion with LARC overlap was smallest for those dispensed dermatological agents (1806 of 14 331 women, 12.6%); for this drug class, both LARC overlap (adjusted odds ratio [aOR], 0.17; 95% confidence interval [CI], 0.14-0.20) and any hormonal contraception overlap (aOR, 0.28; 95% CI, 0.25-0.32) were less likely for those aged 15-19 years than for women aged 25-29 years. CONCLUSIONS: Concurrent use of highly effective hormonal contraception at the time of first dispensing of category X medications is low in Australia, raising concerns about potential fetal harms during unintended pregnancies. Awareness of the importance of hormonal contraception and its uptake by women prescribed category X medications should be increased.

RESUMEN

On January 12, 2024 the safety committee of the European Medicines Agency (EMA) recommended precautionary measures over a potential risk of neurodevelopmental disorders in children born to men treated with valproate. These new measures recommend patient supervision by a specialist in the management of epilepsy, bipolar disorder, or migraine. In the United Kingdom, the Medicines and Healthcare products Regulatory Agency (MHRA) issued a far more stringent precaution, warning against prescribing valproate to anyone under 55 years of age. We, members of the European Network of Teratology Information Services (ENTIS) and the Organization of Teratology Information Specialists (OTIS), believe that the EMA and MHRA warnings were premature. We are of the opinion that the underlying scientific data do not convincingly substantiate the inference of a paternally mediated risk from valproate to children, much less to an extent that justifies these far-reaching recommendations.

RESUMEN

BACKGROUND/OBECTIVES: Oral retinoids are teratogenic, and pregnancy avoidance is an important part of retinoid prescribing. Australia does not have a standardised pregnancy prevention programme for women using oral retinoids, and the contraception strategies for women who use oral retinoids are not well understood. The objectives were to determine trends in the use of prescription retinoids among Australian reproductive-aged women and whether women dispensed oral retinoids used contraception concomitantly. METHODS: This was a population-based study using Australian Pharmaceutical Benefits (PBS) dispensing claims for a random 10% sample of 15-44-year-old Australian women, 2013 - 2021. We described rates and annual trends in dispensing claims for PBS-listed retinoids and contraceptives. We also estimated concomitant oral retinoid and contraceptive use on the day of each retinoid dispensing and determined if there was a period of contraceptive treatment that overlapped. Estimates were then extrapolated to the national level. RESULTS: There were 1,545,800 retinoid dispensings to reproductive-aged women; 57.1% were oral retinoids. The rate of retinoid dispensing to reproductive-aged women increased annually, from 28 dispensings per 1000 population in 2013 to 41 per 1000 in 2021. The rate of oral retinoid dispensing doubled over the study period, from 14 dispensings per 1000 population in 2013 to 28 per 1000 in 2021, while topical retinoid dispensing did not change. Only 25% of oral retinoid dispensings had evidence of concomitant contraceptive use in 2021. CONCLUSIONS: Rates of oral retinoid dispensing have doubled among reproductive-aged women over the past decade. A large percentage of oral retinoid use does not appear to have concomitant contraception use, posing a risk of teratogenic effects in pregnancies.

RESUMEN

OBJECTIVE: In recent years, safety concerns about modafinil exposure during pregnancy have emerged. In particular, increased risks for major congenital anomalies (MCA) and impaired fetal growth were reported, although study results were conflicting. Our investigation aims to examine previously reported safety signals. METHOD: Multicenter case series based on data from 18 Teratology Information Services from 12 countries. Modafinil exposed pregnancies with an estimated date of birth before August 2019 were included in this study. For prospectively ascertained pregnancies, cumulative incidences of pregnancy outcomes, rate of nonchromosomal MCA in first trimester exposed pregnancies and percentiles of neonatal/infant weight and head circumference (HC) were calculated. Potential dose-dependent effects on fetal growth were explored by linear regression models. Retrospectively ascertained cases were screened for pattern of MCA and other adverse events. RESULTS: One hundred and seventy-five prospectively ascertained cases were included, of which 173 were exposed at least during the first trimester. Cumulative incidences for live birth, spontaneous abortion and elective termination of pregnancy were 76.9% (95% CI, 68.0%-84.8%), 9.3% (95% CI, 5.0%-16.9%), and 13.9% (95% CI, 8.1%-23.1%), respectively. Nonchromosomal MCA was present in 3/150 live births, corresponding to an MCA rate of 2.0% (95%CI, 0.6%-6.1%), none were reported in pregnancy losses. Compared to reference standards, birth weight (BW) tended to be lower and neonatal HC to be smaller in exposed newborns (data available for 144 and 73 of 153 live births, respectively). In nonadjusted linear regression models, each 100 mg increase of average dosage per pregnancy day was associated with a decrease in standard deviation score (SDS) of -0.28 SDS (95% CI, -0.45 to -0.10) for BW and of -0.28 SDS (95% CI, -0.56 to 0.01) for HC. Screening of 22 retrospectively reported cases did not reveal any specific pattern of MCA or other adverse outcomes. CONCLUSION: The results do not indicate an increased risk of MCA after in utero exposure to modafinil, but a tendency toward lower BW and reduced neonatal HC. However, these findings should be regarded as preliminary. Until further studies allow for a definite conclusion, modafinil should not be used during pregnancy.

RESUMEN

RESEARCH QUESTION: What are health professionals' clinical practices, views and self-rated competencies regarding the transfer of mosaic embryos? DESIGN: This was a cross-sectional study using surveys. RESULTS: Data were collected from the Royal Australian and New Zealand College of Obstetricians and Gynaecologists and the Fertility Society of Australia and New Zealand. Ninety-five responses were analysed and reported. The results show that most health professionals (n = 62) discussed the transfer of mosaic embryos for different reasons and raised concerns regarding various risks. Although many health professionals were unsure whether mosaic embryos should be transferred, they were more inclined to encourage transfer if the scenario involved segmental losses compared with mosaicism involving duplication of the entire chromosome (i.e. trisomy 21) (e.g. OR = 0.21, P < 0.001; OR = 2.78, P = 0.04). The majority of health professionals would inform patients about the mosaicism to facilitate informed decision making. The factor that health professionals identified as most important when discussing the transfer of mosaic embryos was the specific chromosome involved. Different self-rated competencies were found among health professionals with different backgrounds. Geneticists and genetic counsellors had the highest self-rated competencies. CONCLUSIONS: Most health professionals were willing to discuss the mosaicism in the embryo with patients to facilitate informed decision making. However, health professionals' uncertainty towards the transfer of mosaic embryos indicated a lack of a standardized transfer policy. In addition, obstetricians, gynaecologists and those with multiprofessional backgrounds showed deficiencies in several self-rated competencies, suggesting that education targeted to these groups is needed to optimize the quality of care of women considering transfer of mosaic embryos.

RESUMEN

OBJECTIVE: Because pregnancy outcomes tend to be worse in women with inflammatory bowel disease (IBD) than in those without, we aimed to update consensus statements that guide the clinical management of pregnancy in patients with IBD. DESIGN: A multidisciplinary working group was established to formulate these consensus statements. A modified RAND/UCLA appropriateness method was used, consisting of a literature review, online voting, discussion meeting and a second round of voting. The overall agreement among the delegates and appropriateness of the statement are reported. RESULTS: Agreement was reached for 38/39 statements which provide guidance on management of pregnancy in patients with IBD. Most medications can and should be continued throughout pregnancy, except for methotrexate, allopurinol and new small molecules, such as tofacitinib. Due to limited data, no conclusion was reached on the use of tioguanine during pregnancy. Achieving and maintaining IBD remission before conception and throughout pregnancy is crucial to optimise maternofetal outcomes. This requires a multidisciplinary approach to engage patients, allay anxieties and maximise adherence tomedication. Intestinal ultrasound can be used for disease monitoring during pregnancy, and flexible sigmoidoscopy or MRI where clinically necessary. CONCLUSION: These consensus statements provide up-to-date, comprehensive recommendations for the management of pregnancy in patients with IBD. This will enable a high standard of care for patients with IBD across all clinical settings.

RESUMEN

BACKGROUND: MotherSafe is a free telephone-based counseling service for Australian consumers and health-care providers concerned about drug exposures during pregnancy and breastfeeding. Anti-infectives are the most commonly prescribed drugs for pregnant women. This study aims to provide a descriptive analysis of prospectively collected calls received by MotherSafe regarding anti-infective exposures during pregnancy between 2000 and 2020. Aggregate data were examined by type of caller, reason for call, pregnancy category and exposure type. Inductive thematic analysis of the comments recorded by MotherSafe counsellors at the time of call was undertaken. RESULTS: Over the study period, 25,890 calls related to exposure to anti-infectives during pregnancy (antibiotic, antiviral, and antifungal medications). Calls from patients were dominated by low-risk exposures (pregnancy category A) to drugs while calls from health care professionals related to drugs with limited human information (pregnancy category B3). Analysis of MotherSafe counsellor comments revealed over 200 instances of concerns relating to health care professional advice to the patient. Three themes emerged: incorrect or conflicting advice, poor counselling, and refusal to treat, prescribe or dispense. It is likely that these comments are biased to the negative as patients would not call MotherSafe if they were happy with HCP advice. However, the findings are concerning as they reveal an underlying lack of knowledge in some health care professionals which may have led to undertreatment of patients. This study reinforced the importance of Teratogen Information Services such as MotherSafe in providing counselling and clear communication of evidence-based information to guide decision-making, reducing potential emotional distress in pregnant women, and optimizing maternal, pregnancy and infant outcomes.

RESUMEN

STUDY QUESTION: What are patients' reasoning and decisional needs in relation to the transfer of mosaic embryos following preimplantation genetic testing (PGT)? SUMMARY ANSWER: This study identified four themes, which were patients' reasoning behind decision-making, their decisional needs, the influence of the mosaic embryos on the decision-making and the role of health professionals. WHAT IS KNOWN ALREADY: To date, no study has investigated the reasoning of patients behind their decision-making and the influence of mosaic embryos. STUDY DESIGN SIZE DURATION: This is a cross-sectional study using a qualitative approach. Twenty participants were interviewed, and recruitment was ceased when no new information was identified in the data analysis. It ensured a sufficient sample size for a qualitative study. PARTICIPANTS/MATERIALS SETTING METHODS: Participants were females with mosaic embryos. Semi-structured in-depth interviews were conducted via telephone. MAIN RESULTS AND THE ROLE OF CHANCE: Four themes were identified: reasoning behind decision-making, decisional needs, influence of mosaic embryos on decision-making and the role of health professionals. Potential risks of transferring mosaic embryos and prioritization of euploid embryos were the main reasons for not transferring mosaic embryos. A lack of alternatives, perceived benefits and risk tolerance were main reasons for transferring mosaic embryos. Patients reported that information on mosaic embryos, amniocentesis and termination was important to support their decision-making. Unmet needs relating to healthcare services and social support were reported. In addition, having mosaic embryos affected the patients' emotional and behavioural responses, discussions about prenatal testing, attitudes to termination and further IVF cycles and attitudes towards PGT. Health professionals were found to influence the patients' decision-making. LIMITATIONS REASONS FOR CAUTION: Participants were recruited through one clinic, which may limit the transferability of results. Also, patients' experiences in relation to financial aspects of PGT may not be relevant to other jurisdictions due to different healthcare policies. WIDER IMPLICATIONS OF THE FINDINGS: The results may inform how clinicians provide healthcare services based on factors influencing patients' decision-making. Health professionals should be aware of the influence their attitudes can have on patients' decision-making and should present information accordingly. Also, providing all relevant information may help to facilitate informed decision-making. Provision of psychological support from professionals and support groups is also critical during the process of testing and transfer. Patients have educational needs regarding mosaic embryos, and educational resources including decision aids in plain language are needed. STUDY FUNDING/COMPETING INTERESTS: B.M. was funded through a Senior Research Fellowship Level B (ID 1078523) from the National Health and Medical Research Council of Australia. L.C. was supported by a University International Postgraduate Award under the Australian Government Research Training Program (RTP) scholarship. No other funding was received for this study. The authors report no competing interests. TRIAL REGISTRATION NUMBER: N/A.

RESUMEN

STUDY QUESTION: What are the roles of individual and interpersonal factors in couples' decision-making regarding preimplantation genetic testing for monogenic disorders (PGT-M)? SUMMARY ANSWER: Couples' decision-making regarding PGT-M was associated with individual and interpersonal factors, that is the perceived consistency of information received, satisfaction with information, self-efficacy (individuals' beliefs in their ability to make decisions), actual knowledge about PGT-M and social support from the partner. WHAT IS KNOWN ALREADY: Various factors have been shown to be associated with decision-making regarding PGT-M. However, PGT-M is experienced at an individual level, and to date, no studies have investigated the roles of the above-mentioned individual and interpersonal factors. STUDY DESIGN, SIZE, DURATION: This is a cross-sectional study with 279 participants. Participants were recruited through IVFAustralia, Sydney Children's Hospital and support groups from May 2020 to November 2021. PARTICIPANTS/MATERIALS, SETTING, METHODS: Participants were women who had undergone or were considering PGT-M and their partners. Participants were recruited through IVFAustralia, Sydney Children's Hospital and support groups to complete online questionnaires. Decisional regret, decisional satisfaction and decisional conflict were measured as outcome variables. Multiple linear regressions were performed to examine the association between factors and outcome variables. Mann-Whitney U tests were performed to test the differences between participants who had undergone PGT-M and those who were considering PGT-M. MAIN RESULTS AND THE ROLE OF CHANCE: For couples who had undergone PGT-M, decisional regret was significantly negatively associated with perceived consistency of information received (ß = -0.26, P < 0.01), self-efficacy (ß = -0.25, P < 0.01) and actual knowledge about PGT-M (ß = -0.30, P < 0.001), while decisional satisfaction had positive association with satisfaction with information received (ß = 0.37, P < 0.001) and self-efficacy (ß = 0.24, P < 0.05). For couples who were considering PGT-M, decisional conflict was negatively associated with satisfaction with information received (ß = -0.56, P < 0.001). For females who had undergone PGT-M, decisional regret was negatively associated with social support from the partner (ß = -0.35, P < 0.05) in addition to perceived consistency of information received (ß = -0.24, P < 0.05). In this group, decisional satisfaction was positively associated with women's satisfaction with the information received (ß = 0.34, P < 0.01), social support from the partner (ß = 0.26, P < 0.05) and self-efficacy (ß = 0.25, P < 0.05). For females who were considering PGT-M, decisional conflict was negatively associated with satisfaction with the information received (ß = -0.43, P < 0.01) and social support from the partner (ß = -0.30, P < 0.05). This study also identified those aspects of PGT-M that couples felt most concerned about in relation to their decision-making, in particular safety issues such as short- or long-term health problems for the baby and potential harms to the embryos and the mother's health. The likelihood of getting pregnant and having a baby with a genetic condition being tested for were also important in couples' decision-making. LIMITATIONS, REASONS FOR CAUTION: This study assessed the concerns of couples about having a baby with a variety of genetic conditions. However, condition-specific issues might not be covered. Furthermore, social support from the partner was assessed among females only. Male participants' perceived social support from their partner and the association between mutual support and decision-making were not assessed due to the absence of dyadic data. WIDER IMPLICATIONS OF THE FINDINGS: Results highlight the importance of effective patient education on PGT-M and the need to provide high-quality and consistent information in the context of patient-centred care. Patients are likely to benefit from information that addresses their specific concerns in relation to PGT-M. From females' perspective, support from partners is essential, and partners should, therefore, be encouraged to participate in all stages of the decision-making process. Suggestions for future studies were made. STUDY FUNDING/COMPETING INTEREST(S): B.M. was funded through a Senior Research Fellowship Level B (ID 1078523) from the National Health and Medical Research Council of Australia. L.C. was supported by a University International Postgraduate Award under the Australian Government Research Training Program (RTP) scholarship. No other funding was received for this study.

RESUMEN

This systematic review reports on the needs and sources of support in patients' decision-making regarding the uptake of preimplantation genetic testing (PGT). Five databases were searched systematically to capture qualitative and quantitative studies. A total of 2336 studies were screened by title and abstract. Twelve studies met the eligibility criteria and reported on 4047 participants. This systematic review shows that patients need information directly relevant to PGT treatment, and information on health care relating to treatment and alternative reproductive options. Information that is too detailed, excessive and contains a large volume of medical terminology can be a barrier to decision-making. Published research suggests that health professionals provide general information on PGT and discuss it in detail only when patients require more information about it. Additionally, studies have shown that patients receive decisional support through mass media, significant persons in their lives and health professionals, whereas referring obstetricians and gynaecologists provided relatively less help compared with other health professionals. This systematic review highlights the importance of developing decision aids that meet patients' decisional needs as indicated in previous studies and that use innovative formats to deliver information. Additionally, given rapid technical developments, a dearth of continuing professional education is available on PGT for clinicians to keep updated.

RESUMEN

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.

RESUMEN

This prospective multicentre cohort study investigated pregnancy outcomes after fingolimod use for multiple sclerosis during pregnancy. Pregnancy outcomes of 63 fingolimod and 62 interferon-ß-exposed pregnancies were compared. Rates of major congenital anomalies (MCA) were 4.8% (2/42) in the fingolimod group versus 2.3% (1/44) in the interferon-ß group (odds ratio, 2.2; 95% confidence interval, 0.2-24.6). The adjusted hazard ratio for spontaneous abortion in fingolimod versus interferon-ß-exposed pregnancies was 0.6 (95% confidence interval, 0.2-1.8). Further studies are needed to definitely rule out a moderately increased MCA risk after fingolimod exposure during pregnancy.

RESUMEN

There is a general perception that any exposure to medication during pregnancy poses a potential risk to the fetus. Most available data about teratogenic drugs is derived from animal studies, case reports, or cohort studies. As a result, counseling women and their partners about the safety of drugs during pregnancy can be difficult due to limited information about efficacy, pharmacokinetics, and teratogenicity of some drugs. However, this should always be done in the context of weighing up potential teratogenic risks with the perinatal risks of an untreated medical or psychiatric condition. Ideally, this counseling should occur prior to a planned pregnancy so that medications and treatment of chronic medical conditions can be optimized. It is important that clinicians providing antenatal care are able to confidently manage women including utilizing appropriate resources. This paper aims at reviewing a selected (non-exhaustive) list of the most commonly prescribed medications considered significant human teratogens and provides recommendations for pre-conception and antenatal counseling.

RESUMEN

INTRODUCTION AND AIMS: Few smokers use smoking cessation pharmacotherapies during pregnancy. It is hypothesised that health-care providers' reluctance due to safety concerns contributes to their low use. This study examined the extent of providers' concern regarding smoking cessation pharmacotherapies, relative to other medications in the same and other pregnancy risk categories. Calls made to a teratology information service (MotherSafe, Australia) were taken as a proxy indicator of concern regarding safety during pregnancy. DESIGN AND METHODS: The primary exposure discussed in 66 687 calls made to MotherSafe between 2001 and 2016 was categorised as nicotine replacement therapy (NRT), bupropion, varenicline or category A (low risk), B1, B2, B3, C, D or X (teratogenic). Separate logistic regression models estimated the odds that calls regarding pharmacotherapies were from providers, relative to medications in the same and other risk categories. Models adjusted for caller remoteness and socio-economic status. RESULTS: Calls regarding bupropion were more likely to be made by providers than calls regarding other medications in its corresponding risk category [B2, adjusted odds ratio (aOR): 2.77, 95% confidence interval (CI) 1.17, 6.59]. Calls about varenicline were also more likely to be from providers than calls regarding other category B3 medications (aOR 95% CI 2.33:1.30, 4.17). Calls regarding NRT were not more or less likely to be from providers than calls regarding other category D medications. DISCUSSION AND CONCLUSIONS: Providers were more concerned about bupropion and varenicline than other medications within the same pregnancy risk categories. As this overestimation of risk may limit cessation pharmacotherapy use during pregnancy, research investigating strategies for correcting this imbalance is warranted.

RESUMEN

BACKGROUND: MotherSafe is a free telephone counselling service for exposures during pregnancy and breastfeeding. As the last health professional seen prior to consumption of medicines, community pharmacists' opinions on the use of medications in pregnancy/breastfeeding is likely to be particularly sought by women presenting in pharmacies. However, a recent qualitative study revealed that community pharmacists feel unsupported in their role as medicine information providers to pregnant/breastfeeding women. AIM: The aim of the current study was to undertake a descriptive analysis of calls made by pharmacists or pharmacist-referred patients to MotherSafe across the time period 2000-2018. MATERIALS AND METHODS: A retrospective, descriptive study was conducted of call data from January 2000 to December 2018. Aggregate data were examined by type of caller, reason for call, pregnancy category and exposure type. RESULTS: Most calls (57%) related to pregnancy or breastfeeding (39%) with calls equally distributed throughout gestation. Calls regarding potential pregnancy exposures to uncategorised drugs were the most frequent (mainly complementary medicines). Unlike pharmacists, calls from pregnant consumers referred by pharmacists were also frequently regarding category A drugs. CONCLUSIONS: This study highlights the need for reliable evidence-based information sources regarding the use of prescribed medications, over-the-counter and complementary preparations during pregnancy and breastfeeding. There is a need for better education of pharmacists about appropriate information sources and the need to use evidence-based resources other than the A-X categories to advise their clients about the safety or otherwise of medications in pregnancy and breastfeeding.

RESUMEN

Background: MotherSafe is a free telephone-based counseling service for Australian consumers and health care providers concerned about drug exposures during pregnancy and breastfeeding. Calls relating to breastfeeding are relatively common and a source of significant distress to the breastfeeding mother, particularly if there is a lack of clarity regarding possible adverse effects of drug exposure on the infant. This study seeks to identify the medication exposures of concern for breastfeeding mothers and the information available to address these concerns. Aims: To review calls to MotherSafe about breastfeeding drug exposures during the 19-year period from 2000 to 2018 and to highlight drugs of concern and counseling issues. Materials and Methods: A retrospective descriptive assessment of a prospectively collected Access database was undertaken. Phone counseling records identified the medication (and other) exposures of concern regarding breastfeeding. The information about medication exposures via breastfeeding provided in consumer and product information (PI) was also reviewed. Results: Of a total of 315,158 calls received at MotherSafe between 2000 and 2018, 116,876 (37.1%) were regarding drug exposure via breastfeeding; 30% of these calls related to nonsteroidal anti-inflammatory drugs, antihistamines, antidepressants, simple analgesics, and antibiotics, and 5% were regarding an exposure specifically contraindicated when breastfeeding. Conclusions: Queries about medication exposures via breastfeeding represent a significant proportion of all the counseling calls to MotherSafe. This study demonstrates the inconsistent and often misleading information about breastfeeding exposures found in consumer and PI sheets and online and highlights the important role of Teratogen Information Services like MotherSafe in providing evidence-based information to both consumers and health care providers.

RESUMEN

BACKGROUND: Pain during pregnancy is common, and its management is complex. Certain analgesics may increase the risk for adverse fetal and pregnancy outcomes, while poorly managed pain can result in adverse maternal outcomes such as depression and hypertension. Guidelines to assist clinicians in assessing risks and benefits of exposure to analgesics for the mother and unborn infant are lacking, necessitating evidence-based recommendations for managing pain in pregnancy. METHODS: A comprehensive literature search was conducted to assess pregnancy safety data for pharmacological and nonpharmacological pain management methods. Relevant clinical trials and observational studies were identified using multiple medical databases, and included studies were evaluated for quality and possible biases. RESULTS: Paracetamol and nonsteroidal anti-inflammatory drugs (NSAIDs) are appropriate for mild to moderate pain, but NSAIDs should be avoided in the third trimester due to established risks. Short courses of weaker opioids are generally safe in pregnancy, although neonatal abstinence syndrome must be monitored following third trimester exposure. Limited safety data for pregabalin and gabapentin indicate that these are unlikely to be major teratogens, and tricyclic antidepressants and serotonin-norepinephrine reuptake inhibitors have limited but overall reassuring safety data. Many of the included studies were limited by methodological issues. CONCLUSIONS: Findings from this review can guide clinicians in their decision to prescribe analgesics for pregnant women. Treatment should be tailored to the lowest therapeutic dose and shortest possible duration, and management should involve a discussion of risks and benefits and monitoring for response. Further research is required to better understand the safety profile of various analgesics in pregnancy.
