Phentermine is a drug primarily used as an appetite suppressant. Chemically, it is an amphetamine (and a phenethylamine). It is typically prescribed for individuals who are at increased medical risk because of their weight, as opposed to cosmetic weight loss. Phentermine is sold either as an immediate-release formulation (Adipex®) or as a slow-release resin.
