What antiseizure medication should be avoided in women of childbearing age?

Valproic acid is the medication that should be avoided in women of childbearing age due to its significant teratogenic effects. This anticonvulsant is associated with a higher risk of birth defects, particularly neural tube defects, when taken during pregnancy. The risks include not only structural anomalies but also cognitive developmental issues in children exposed to the drug in utero. As a result, healthcare providers often recommend alternative medications for women of childbearing age who require treatment for epilepsy or seizures to minimize these risks.

In contrast, while lamotrigine, Keppra (levetiracetam), and phenytoin also have considerations in pregnancy, their risk profiles do not mandate the same level of caution as valproic acid. Thus, valproic acid is specifically highlighted for its serious implications for fetal development.
