With close cooperation and communication among the obstetrician, neurologist, pediatrician, and patient, most women with idiopathic epilepsy who become pregnant will have an uneventful pregnancy with an excellent outcome. To optimize the neonatal outcome in a patient requiring medication, using a single drug at the lowest possible dose that keeps her free of seizures is preferable. The prevention of tonic-clonic seizures, however, is of utmost importance. Simple interventions such as avoiding sleep deprivation, having the patients take folic acid before conception, and giving the infant a vitamin K injection at birth will help optimize the outcome. There is an increase of congenital malformations in infants born to women with epilepsy; however, the incidence is low. Most women with epilepsy will experience normal pregnancy and labor and will have spontaneous vaginal deliveries of healthy babies.
