How Long Does It Take to Lose Weight on Topamax?


Quick Answer

Topamax, formally known as topiramate, is not normally prescribed for weight loss, but rather as a medication for other conditions; although, it has been known to help patients achieve weight loss over the course that it has been prescribed, which can range anywhere from 2 to 4 weeks to 8.5 weeks, according to a paper published by the National Center for Biotechnology Information. Topiramate reaches peak levels in the body within 1.75 to 4.3 hours, and will begin to help with weight loss although results may not be noticed immediately. Depending on the treatment that topiramate was originally prescribed for, dosages range anywhere from 100 to 375mg per day with the average total weight loss being 22 pounds.
