Weight loss medications.

Weight-loss medications are drugs used to suppress appetite, increase the feeling of fullness, affect how dietary fat is absorbed, or otherwise change how people eat and absorb food. Their purpose is to support diet and exercise as methods of losing weight. Most require a prescription from a physician and are generally prescribed only for people with a great deal of weight to lose and/or additional health problems caused by excess weight. Some of these medications are designed to be used for weight loss; others were originally approved for other conditions but have weight loss as a side effect. Some weight loss medications may cause side effects and not be appropriate for everyone.
