Pregnant women who took a popular epilepsy drug, also widely used to treat migraines, pain and psychiatric disorders, had children whose I.Q. scores were significantly lower than those whose mothers took a different antiseizure medication, a new study has found.
The drug, valproate, sold generically and under the brand name Depakote, remains the second-most-popular antiseizure medication used for epilepsy, but earlier studies found that use during pregnancy also increased the risk of developmental delays and major malformations.
The risks that other epilepsy drugs may pose are not clear, experts say. While some are likely to be safer than others, there have not been enough studies to guide patients and their doctors. About half of the women who take valproate are not epileptics.
