This older anticonvulsant medication was used to treat absence seizures (petit mal epilepsy) that did not respond to other treatments. It works by reducing abnormal electrical activity in the brain. Due to serious toxicity risks including fetal harm, liver damage, and kidney problems, it has been largely replaced by safer medications and is rarely used today.
