In a pregnancy cohort (2015-2021) and a cohort of women of childbearing age (2021 and 2018), we defined three 90-day time periods: (1) first trimester, (2) preconceptional period (days 180-90 before pregnancy), and (3) January 01, 2021, and March 31, 2021 (women of childbearing age). During all periods, we quantified the exposure prevalence to at least one dispensed weak, proven, and unequivocally potent teratogen overall and by age strata. We quantified the exposure prevalence to each individual teratogen, and to valproate during pregnancy by calendar year to compare its use before and after the introduction of a pregnancy prevention program (2018).

Systemic glucocorticoids were the most prevalent weak teratogens during all time periods (75% of all claimed teratogens during the first trimester). In the first trimester, the antibiotic cotrimoxazole and the thyreostatic thiamazole (weak teratogens), ranked second and third, followed by the antiseizure medications carbamazepine and topiramate (proven teratogens). Among women of childbearing age, exposure to weak and proven teratogens increased with age, whereas exposure to unequivocally potent teratogens decreased with age.
