Patient Education

Topiramate


Topiramate is used alone or with other medications to treat certain types of seizures including primary generalized tonic-clonic seizures (formerly known as a grand mal seizure; seizure that involves the entire body) and partial onset seizures (seizures that involve only one part of the brain). Topiramate is also used with other medications to control seizures in people who have Lennox-Gastaut syndrome (a disorder that causes seizures and developmental delays). Topiramate is also used to prevent migraine headaches but not to relieve the pain of migraine headaches when they occur. Topiramate is in a class of medications called anticonvulsants. It works by decreasing abnormal excitement in the brain.
