Children who have been exposed to Valproate in the womb are at high risk of serious developmental disorders (in up to 30-40% of cases) and congenital malformations (in about 10% of cases). Girls and women should only take Valproate-containing medication if other treatments are not effective or are not tolerated and if a contraceptive programme is followed.
