Topamax is prescribed to treat seizures in adults and children over 2 years of age and also to prevent migraines in adults and teenagers 12 years and older, states Drugs.com. Studies show that the anti-epileptic agent Topamax is associated with weight loss because it is an effective treatment for binge-eating disorders often associated with obesity, reports the National Center for Biotechnology Information. When compared with a placebo, Topamax given in daily doses ranging from 50 to 600 milligrams resulted in significant reductions in binging frequency, body mass index and weight.
