Diet drugs are prescribed for patients who have difficulty losing weight through traditional means such as diet and exercise. Many diet drugs work to treat obesity through appetite suppression. Most diet drugs are only prescribed for short-term use; however, there are two drugs that are approved for long-term use: Meridia® and Xenical®.
Diet Drug Side Effects
As with any type of drug, there are side effects associated with diet drugs. Some of the side effects of diet drugs include:
- Heart valve irregularities
- Primary pulmonary hypertension
- Liver failure
The FDA issued a recall of the diet drug Fen-Phen after it was linked to heart valve irregularities and primary pulmonary hypertension.
