topomax Topiramate






Topamax (topiramate) is an anticonvulsant used to control and prevent seizures (epilepsy). Topiramate is used to treat seizures in adults and children who are at least 2 years old.

It is also used for migraine headache prevention in adults and teenagers who are at least 12 years old. This medicine will only prevent migraine headaches or reduce the number of attacks. It will not treat a headache that has already begun.

It works by helping change certain chemicals in the brain, which professionals refer to as “neurotransmitters.” It is not yet well-understood why changing these neurochemicals results in symptom relief for the conditions this drug is commonly prescribed for.

    Before I started taking the medication my entire head was so sensitive that it hurt to touch my scalp. Now I can not only be pain free most of the time from migraines but also have long hair and wear my hair in different ways. This medication has really helped me. I get the headaches due to allergies so I take an allergy med at night with 100mg of Topamax.
