Effects of Topamax
Topamax® (topiramate) is a prescription medication approved to treat epileptic seizures and prevent migraines. Specifically, the drug is approved for treating epilepsy either alone (for children age 10 and up) or in combination with other medications (for children age two and up).
Topamax has not been adequately studied for migraine prevention in children and is not approved for this use.
Although it is not entirely clear how this medication works for epilepsy or migraines, the effects of Topamax may include slowing down abnormal electrical signals in the brain. It is also thought that migraines may be triggered by nerve cells in the brain that are too easily excited. Topamax can help calm these nerve cells, working to prevent a migraine from ever starting.
In studies on Topamax effects, this medication increased the time until the next seizure and decreased the number of seizures. In one study of adults with epilepsy, approximately 75 percent of people taking 400 mg of the drug per day were seizure-free for at least one year.
In one study that used Topamax for preventing migraines, 200 mg per day reduced the average number of migraines from 5.5 per month to 3.1 per month.
Although most people have no problems with this medication, it is possible to experience side effects. Topamax can cause problems such as drowsiness, dizziness, and nervousness.
