Adipex is an oral appetite suppressant that is prescribed for the short-term treatment of obesity. Adipex is generally used for only a few weeks as part of an overall weight loss program that may include dieting, exercise, and counseling. Only excessively overweight individuals who have conditions, such as diabetes, high blood pressure, or high cholesterol, which could lead to serious medical problems, should use Adipex. Adipex is not meant for everyone.
