Many people with epilepsy stop taking antiepileptic drugs when they find out they are pregnant, which is very undesirable. Stopping medication suddenly or changing treatment regimens without permission is likely to worsen the epilepsy, and if seizures are not well controlled during pregnancy, it can be very harmful to the patient and the fetus. For many women with epilepsy, the risk of staying on medication during pregnancy is less than stopping it without permission. Most women with epilepsy have normal pregnancies and deliveries and have a better than 90% chance of having a healthy fetus. Therefore, it is important not to stop medication or change treatment regimens suddenly without medical supervision and management.
