Women with epilepsy frequently require antiseizure medication (ASM) during pregnancy, and precise knowledge is needed about the safety for the exposed child.
1 Five in 1000 pregnant women use ASMs, and this use is increasing.
1,2 Discontinuation before or during pregnancy is associated with uncontrolled seizures and increased maternal mortality.
3,4 This places the patient and physician in a difficult position because some ASMs are teratogenic and may increase the risk of neurodevelopmental disorders.
5,6 Previous studies have shown a 3- to 5-fold increased risk of autism spectrum disorder (ASD) and intellectual disability (ID) in children after prenatal exposure to valproate.
7-10 However, for most other ASMs, the risk of neurodevelopmental disorders after prenatal exposure remains uncertain despite their frequent use.
5,7-15 The risk is unknown for commonly used combination therapies, but in some patients, seizure control can only be achieved by combining different ASMs.
