Topomax is the misspelling of the prescription drug, Topamax (Topiramate). It is an anticonvulsant and anti-seizure medication that, in stronger doses us used to control epilepsy. In smaller amounts prescribed under the brand name Topamax, it is used to help control severe migraines in both frequency and severity.
I use to get migraines two to three days a week until I began taking Topomax/Topamax. Now I hardly ever get them.
