According to recent experiences There are no specific teratogenic effe
cts of antiepileptic drugs in humans. Polytherapy is associated with m
alformations more often than monotherapy. This does not apply to minor
anomalies. Concerns regarding neural tube defects because of intraute
rine valproate - or carbamazepine - exposure can be met by taking a ca
reful history regarding individual or family predisposition to defects
or anomalies dividing the daily dose into several single doses folate
supplementation prior and during pregnancy antenatal monitoring. Thos
e minor anomalies (hypertelorism, distal digital hypoplasies), which m
ay possible be induced by antiepileptic drugs harmonize or dissappear
during further development. Most minor anomalies, small body measureme
nts, small head cicumferences and cognitive dysfunction are not caused
by ingestion of antiepileptic drugs during pregnancy.
