Teratogenesis, Perinatal, and Neurodevelopmental Outcomes After in Utero Exposure to Antiseizure Medication

Publication Date: May 15, 2024

Key Points

Key Points

  • Prioritize shared decision-making with people with epilepsy of childbearing potential (PWECP) to find the proper combination of medications that optimize both seizure control and fetal outcomes before pregnancy.
  • Stopping antiseizure medications (ASMs) during pregnancy can increase seizure frequency, which can harm both the patient and the child.
  • Avoid valproic acid, phenobarbital, and topiramate (in that order) if clinically feasible to minimize risk of major congenital malformations (MCMs) and unfavorable perinatal and neurodevelopmental outcomes.
  • Recommend folic acid supplementation for PWECP to decrease the risk of neural tube defects, possibly decrease the risk of autism spectrum disorder, and help improve IQ in their offspring.
