Does Valproate Increase Levels of Folate Receptor Autoantibodies in Women?

October 23, 2015 updated by: Northwell Health
Women who take folate (folic acid) before getting pregnant can lower the risk of giving birth to infant with certain birth defects. However, some medications may affect the action of folate. The purpose of this study is to compare the effect of two anti-epileptic drugs on how folate works in our body.
