Description: The antiseizure drug Depakote has been linked to birth defects and lower IQs among children exposed to it in the womb, but millions of American women may be taking it without knowing the risks, a group of epilepsy experts warned Tuesday. Officials with the Epilepsy Foundation and the American Epilepsy Society said as many as 15 million prescriptions for antiseizure drugs are written each year to women in their childbearing years. The drugs are commonly used to treat migraine headaches and bipolar disorder in addition to epilepsy.
