What Is Topiramate 25mg?
Topiramate is a prescription anticonvulsant medication, sold under the brand name Topamax, that works by calming overactive nerve signals in the brain. It is FDA-approved to treat certain seizure disorders, including partial-onset and primary generalized tonic-clonic seizures, and as an add-on therapy for seizures associated with Lennox-Gastaut syndrome. Topiramate is also approved to help prevent migraine headaches, though it does not treat a migraine once it has started. The 25mg tablet strength is commonly used when starting therapy, with doses increased gradually under a provider's guidance.
