Major Congenital Malformations in Offspring of Women with Epilepsy

Dina Battino, Torbjörn Tomson

Research output: Chapter in Book/Report/Conference proceedingChapter


It has long been known that the risk of major congenital malformations is increased among children of mothers with epilepsy. This is mainly due to the teratogenic effects of antiepileptic drugs. Recent large-scale prospective epilepsy and pregnancy registries have indicated that the rate of major congenital malformations may be up to twofold higher than expected with exposure in utero to the presently most frequently used antiepileptic drugs such as carbamazepine or lamotrigine, Higher rates are consistently reported with exposure to valproic acid. The risk of teratogenic effects appears to be dose-dependent and the lowest effective dose should thus be tried before pregnancy regardless of which antiepileptic drug the woman is taking. Major changes such as switches between drugs should be avoided when pregnancy is established.
