Summary
This cohort study in JAMA Network Open aimed to determine whether US Food and Drug Administration (FDA) warnings to prevent prenatal exposure to valproic acid are associated with changes in pregnancy risk and contraceptive use.
The study examined 165 772 valproic acid treatment episodes among 69 390 women and found that pregnancy rates during treatment remained unchanged during the 15-year study, and were more than doubled among users with mood disorder or migraine compared with epilepsy. Contraception use among users was uncommon, with only 22.3% of treatment episodes having a 1-day overlap of valproic acid and contraception use.
The authors argue that these findings suggest a need to review efforts to prevent prenatal exposure to valproic acid, especially for clinical indications where risk of use during pregnancy outweighs therapeutic benefit and safer alternatives are available.
