Specific Birth Defects Following Antiseizure Medications Used By Pregnant Women With Epilepsy.

Our findings support avoidance of valproic acid use in pregnancy whenever possible. Lamotrigine and carbamazepine may be safer alternatives.

We are among the first to examine the possible effects of levetiracetam use in pregnancy, though more research is needed to investigate this further.
