What is Topamax and what is it prescribed for?

Topomax is the brand name of the anticonvulsant drug topiramate. It is sold as a tablet (pill) and prescribed alone or with other drugs to control certain types of epileptic seizures or to prevent migraine headaches. The FDA has approved it for these uses. The FDA says it has also been prescribed “off-label” for other conditions.

From January 2007 through December 2010, approximately 32.3 million topiramate prescriptions were written in the U.S., the FDA says.
