Pregnancy and Folic Acid in Women With Epilepsy

High doses of folic acid, defined as 1 milligram or greater, may increase the risk of childhood cancer. Children born to mothers with epilepsy who were exposed to high dose folic acid are 2.7 times more likely to develop childhood cancer. The AAN is working on rewriting the guidelines on management of pregnant women with epilepsy and these are expected to be released in 2023.
