Mysoline is an anticonvulsant drug that works to prevent and treat seizures. It is typically taken alone, but it can be used together with other drugs. A seizure is typically a sudden surge of electrical activity in the brain that is conducted through the brain's nerves. Mysoline works by decreasing these nerve impulses which can cause remission and reduce seizures.
