Women's beliefs about medication use during their pregnancy: a UK perspective
Background: Previous research has examined the number and extent of medicines taking in pregnant women but not their beliefs and risk perception surrounding their use. Objective: To describe beliefs and risk perception associated with medicines use for the treatment of common acute conditions among UK women and explore whether this is related to actual medicines use. Settings: Cross-sectional, web-based study in the UK Methods: Pregnant women and mothers within one year of giving birth were invited to participate in an online cross-sectional questionnaire-based study via a pregnancy website in the UK. Anonymous data were collected from women regarding their use of medicines (both over-the-counter and prescribed) and their beliefs regarding medicines use during pregnancy. Main outcome measures: Pregnant womenâs beliefs about medicines and their relation to pharmacological treatment of acute conditions in pregnancy. Results: Pharmacological treatment of conditions in pregnancy ranged from 65.4% for urinary tract infections (UTIs) to 1.1% for sleeping problems. Almost three out of ten women avoided using some medications during pregnancy. For heartburn and UTIs, women who did not treat the condition viewed medicines in general as being overused, more harmful and less beneficial, than those who treated the condition. In general, UK pregnant women perceived medicines to be beneficial and slightly overused. Conclusions: Womenâs beliefs about medications impact on treatment of specific conditions in pregnancy such as heartburn and UTIs. Healthcare professionals should explore patientâs beliefs regarding medication at the first maternity care visit to promote appropriate medication use in pregnancy
Antithyroid drug use during pregnancy and the risk of birth defects in offspring:systematic review and meta-analysis of observational studies with methodological considerations
Aims
Maternal antithyroid drug (ATD) use during pregnancy has been associated with an increased risk of birth defects in offspring. Uncertainty remains on the size of this risk and how it compares to untreated hyperthyroidism due to methodological limitations of previous studies.
Methods
Systematic review of MEDLINE and EMBASE identifying observational studies examining ATD use during pregnancy and risk of birth defects by 28 August 2020. Data were extracted on study characteristics, effect estimates and comparator groups. Adjusted effect estimates were pooled using a random-effects generic inverse variance method and absolute risk calculated.
Results
Seven cohort studies and 1 caseâcontrol study involving 6â212â322 pregnancies and 388â976 birth defects were identified reporting regression effect estimates. Compared to an unexposed population comparison, the association between ATD use during pregnancy and birth defects in offspring was: adjusted risk ratio (aRR) 1.16 95% confidence interval (CI) 1.08â1.25 for propylthiouracil (PTU); aRR 1.28 95%CI 1.06â1.54 for methimazole/carbimazole (MMI/CMZ); aRR 1.51, 95%CI 1.16â1.97 for both MMI/CMZ and PTU; and aRR 1.15 95%CI 1.02â1.29 for untreated hyperthyroidism. The excess risk of any and major birth defects per 1000, respectively, was: 10.2 and 1.3 for PTU; 17.8 and 2.3 for MMI/CMZ; 32.5 and 4.1 for both MMI/CMZ and PTU; and 9.6 and 1.2 for untreated hyperthyroidism.
Conclusions
When appropriately analysed the risk of birth defects associated with ATD use in pregnancy is attenuated. Although still elevated, the risk of birth defects is smallest with PTU compared to MMI/CMZ and may be similar to that of untreated hyperthyroidism

The burden of nausea and vomiting during pregnancy: severe impacts on quality of life, daily life functioning and willingness to become pregnant again â results from a cross-sectional study
Background: Though nausea and vomiting is very common during pregnancy, no studies have investigated the impact of this condition on the womenâs daily lives in a Scandinavian population. The aim of this study was to describe the burden of nausea and vomiting during pregnancy (NVP) on global quality of life, daily life functioning and willingness to become pregnant again according to the severity of NVP symptoms. Methods: This study is a cross-sectional population-based study conducted in Norway. Pregnant women and mothers with children <1 year of age with current or prior NVP were eligible to participate. Data were collected through an anonymous on-line questionnaire accessible from November 10th, 2014 to January 31st, 2015. Severity of NVP was measured using the 24-h Pregnancy Unique Quantification of Emesis Scale (PUQE). Associations between severity of NVP, daily life functioning and willingness to become pregnant again were tested using chisquare tests. Associations with global quality of life measured in terms of the Quality of Life Scale (QOLS) were estimated using generalized linear models and reported as unstandardized regression coefficients (ÎČ) with 95% confidence intervals (CI). Results: 712 women with NVP were included in the study. NVP was significantly associated with several characteristics, including daily life functioning, quality of life and willingness to become pregnant again. The negative impact was greater the more severe the symptoms were, although considerable adverse effects were also seen among women with mild and moderate NVP symptoms. Over one fourth of the women with severe NVP considered terminating the pregnancy due to NVP, and three in four considered not to get pregnant again. Severity of NVP remained significantly associated with reduced global quality of life when adjusting for maternal characteristics and illnesses with ÎČ (95% CI) = â10.9 (â16.9, â4.9) for severe versus mild NVP. Conclusions: NVP as measured by PUQE had a major impact on various aspects of the womenâs lives, including global quality of life and willingness to become pregnant again.publishedVersio
Longitudinal changes in neurodevelopmental outcomes between 18 and 36 months in children with prenatal triptan exposure: findings from the Norwegian Mother and Child Cohort Study
OBJECTIVE: This study sought to determine whether changes in neurodevelopmental outcomes between 18 and 36 months of age were associated with prenatal exposure to triptan medications, a class of 5-HT receptor agonists used in the treatment of migraine.
METHOD: Using data from the Norwegian Mother and Child Cohort Study, a prospective birth cohort that includes nearly 40% of all pregnancies in Norway from 1999 to 2008, we identified 50 469 mother-child dyads who met inclusion criteria and were present for at least one follow-up assessment at 18 or 36 months postpartum. Neurodevelopment was assessed using the Child Behaviour Checklist, the Emotionality, Activity, and Shyness Questionnaire, and the Ages and Stages Questionnaire. We used generalised estimating equations to evaluate change from 18 to 36 months for children prenatally exposed to triptans, relative to contrast groups, and used marginal structural models with inverse probability of treatment and censoring weights to address time-varying exposure and confounding as well as loss to follow-up.
RESULTS: Among eligible participants (n=50 469), 1.0% used a triptan during pregnancy, 2.0% used triptans prior to pregnancy only, 8.0% reported migraine without triptan use and 89.0% had no history of migraine. Children with prenatal triptan exposure had greater increases in emotionality (r-RR 2.18, 95% CI 1.03 to 4.53) and activity problems (r-RR 1.70, 95% CI 1.02 to 2.8) compared to children born to mothers who discontinued triptan use prior to pregnancy.
CONCLUSION: Prenatal triptan exposure was associated with changes over time in externalising-type behaviours such as emotionality and activity, but not with internalising-type behaviours
Ondansetron use in nausea and vomiting during pregnancy:A descriptive analysis of prescription patterns and patient characteristics in UK general practice
AIMS: The objective of this study was to describe ondansetron drug utilization patterns during pregnancy to treat nausea and vomiting in pregnancy (NVP). Moreover, we aimed to describe the maternal factors associated with NVP and antiemetic use. METHODS: The data consist of pregnancies with a live birth(s) within an IMRDâUK registered GP practice. Descriptive statistics were used to investigate patterns of ondansetron use in pregnancy and to describe maternal characteristics associated with NVP and antiemetic drug utilization. We differentiate firstâ from secondâline use during pregnancy using antiemetic prescription pathways. RESULTS: The dataset included 733â633 recorded complete pregnancies from 2005 to 2019. NVP diagnosis and ondansetron prescription prevalence increased from 2.7% and 0.1% in 2005 to 4.8% and 2.5% in 2019 respectively. Over the period 2015â2019, the most common oral daily dosages were 4Â mg/d (8.5%), 8Â mg/d (37.1%), 12âmg/d (37.5%) and between 16 and 24âmg/d (16.9%). Prescription of ondansetron was initiated during the first trimester of pregnancy in 40% of the cases and was moderately used as a firstâline therapy (2.8%), but preferred choice of secondâline therapy. Women with mental health disorders, asthma and/or prescribed folic acid were more likely to experience NVP and use antiemetics in pregnancy than their counterparts. CONCLUSION: This study confirms that ondansetron is increasingly used offâlabel to treat NVP during pregnancy, also in the first trimester and before other prescription antiemetics have been prescribed. Several maternal comorbidities and folic acid use were more common among women experiencing NVP and using antiemetics, including ondansetron
Antihistamine use during breastfeeding with focus on breast milk transfer and safety in humans - a systematic literature review.
Current data on use of antihistamines during breastfeeding and risks to the breastfed infant are insufficient. The aim of this systematic review was to provide an overview of studies measuring the levels of antihistamines in human breast milk, estimating the exposure for breastfed infants, and/or reporting possible adverse effects on the breastfed infant. An additional aim was to review the antihistamine product labels available in EU and the US. We searched seven online databases and identified seven human lactation studies that included 25 mother-infant pairs covering cetirizine, clemastine, ebastine, epinastine, loratadine, terfenadine and triprolidine. In addition, one study investigated the impact of chlorpheniramine or promethazine on prolactin levels among 17 women, and one study investigated possible adverse drug reactions in 85 breastfed infants exposed to various antihistamines. The relative infant dose was below 5% for all antihistamines, ranging from 0.3% for terfenadine to 4.5% for clemastine. Most product labels of the ten antihistamines with available information in both EU and the US, reported lack of evidence and recommended to avoid use during breastfeeding. The knowledge gap on antihistamines and lactation is extensive, and further human studies are warranted to ensure optimal treatment of breastfeeding women with allergy
Timing of Antidepressant Discontinuation During Pregnancy and Postpartum Psychiatric Outcomes in Denmark and Norway
Importance: Approximately half of women discontinue antidepressant use during pregnancy, yet this could lead to relapse in the postpartum period.
Objective: To investigate the associations between longitudinal antidepressant fill trajectories during pregnancy and postpartum psychiatric outcomes.
Design and setting, and participants: Cohort study using nationwide registers in Denmark and Norway. Participants included 41,475 liveborn singleton pregnancies in Denmark (1997â2016) and 16,459 in Norway (2009â2018) for women who filled at least one antidepressant prescription within six months before pregnancy.
Exposures: Antidepressant prescription fills were obtained from the prescription registers. Antidepressant treatment during pregnancy was modeled using longitudinal k-means.
Main outcomes and measures: Initiating psycholeptics, psychiatric emergency, or records of self-harm within one year postpartum. Hazard ratio (HR) of each psychiatric outcome was estimated using Cox regression models. Inverse probability of treatment weighting was used to control for confounding. Country-specific HRs were pooled using random-effects meta-analytic models.
Results: Of 57,934 pregnancies (mean maternal age range across countries: 30.7â ?? years), [XL1] our trajectories were identified: early discontinuers (about 30% of the population), late discontinuers (previously stable users) (20â25%), late discontinuers (short-term users) (15â20%), and continuers (25â30%). Early discontinuers and late discontinuers (short-term users) had a lower probability of initiating psycholeptics and having postpartum psychiatric emergencies compared to continuers. We found a moderately increased probability of initiation of psycholeptics among late discontinuers (previously stable users) compared to continuers (HR=1.13, 95% CI: 1.03â1.24). This increase in late discontinuers (previously stable users) was more pronounced among women with previous affective disorders (HR=1.28, 95% CI: 1.12â1.47). No association between antidepressant fill trajectories and postpartum self-harm risk was found.
Conclusions and Relevance: Using pooled data from Denmark and Norway, we found a moderately elevated probability of initiation of psycholeptics in late discontinuers (previously stable users) compared to continuers.
[XL1]Mean (SD) age of the study population was 30.7(5.3) year
Mental health of pregnant and postpartum women during the third wave of the COVID-19 pandemic: a European cross-sectional study.
OBJECTIVE
To describe the mental health of perinatal women in five European countries during the third pandemic wave and identify risk factors related to depressive and anxiety symptoms.
DESIGN
A cross-sectional, online survey-based study.
SETTING
Belgium, Norway, Switzerland, the Netherlands and the UK, 10 June 2021-22 August 2021.
PARTICIPANTS
Pregnant and up to 3 months postpartum women, older than 18 years of age.
PRIMARY OUTCOME MEASURE
The Edinburgh Depression Scale (EDS) and the Generalised Anxiety Disorder scale (GAD-7) were used to assess mental health status. Univariate and multivariate generalised linear models were performed to identify factors associated with poor mental health.
RESULTS
5210âwomen participated (including 3411 pregnant and 1799 postpartum women). The prevalence of major depressive symptoms (EDS â„13) was 16.1% in the pregnancy group and 17.0% in the postpartum . Moderate to severe generalised anxiety symptoms (GAD â„10) were found among 17.3% of the pregnant and 17.7% of the postpartum women. Risk factors associated with poor mental health included having a pre-existing mental illness, a chronic somatic illness, having had COVID-19 or its symptoms, smoking, unplanned pregnancy and country of residence. Among COVID-19 restrictive measures specific to perinatal care, pregnant and postpartum women were most anxious about not having their partner present at the time of delivery, that their partner had to leave the hospital early and to be separated from their newborn after the delivery.
CONCLUSION
Approximately one in six pregnant or postpartum women reported major depression or anxiety symptoms during the third wave of the pandemic. These findings suggest a continued need to monitor depression and anxiety in pregnancy and postpartum populations throughout and in the wake of the pandemic. Tailored support and counselling are essential to reduce the burden of the pandemic on perinatal and infant mental health
