Seizure medicine does work on treating migraines. However, it is not clear how seizure medicine works to prevent migraines. Examples like topiramate and valproate are seizure medicines that are typically used to control seizures in people who have epilepsy. These medicines can reduce the number of migraines you get each month by more than half.
It's important not to use valproate if you are pregnant, breast-feeding, or planning to get pregnant because it might increase the chance of birth defects. If you have to use this medicine, talk to your doctor about how you can prevent pregnancy.
If you have ever had kidney stones, make sure to tell your doctor before you take topiramate because taking topiramate may increase your risk of having kidney stones again.
