Antiseizure Drugs and Pregnancy: What You Need to Know

When you're pregnant and managing antiseizure drugs, medications used to control epileptic seizures and other neurological conditions. Also known as anti-epileptic drugs, they help prevent dangerous seizures—but their impact on a developing baby is a real concern.

The goal isn’t to avoid all meds—it’s to pick the safest one for you and your baby.

Fetal development, the process by which a baby grows inside the womb is sensitive to certain chemicals. Some antiseizure drugs, medications used to control epileptic seizures and other neurological conditions like valproate carry a high risk of birth defects—think spina bifida, heart problems, or learning delays. Others, like lamotrigine or levetiracetam, are much safer and are often first choices today. Your doctor won’t just look at the drug name—they’ll check your seizure type, how long you’ve been on it, and whether you’ve had seizures in the last year. Changing meds mid-pregnancy isn’t always the answer; sometimes staying stable is the best move.

Hormone shifts, sleep loss, and stress can trigger more seizures. That’s why monitoring isn’t optional—it’s essential.
