Three Weight Loss Supplements Found to Contain Drugs

On September 12, 2014, the FDA warned consumers not to buy or use the weight loss supplements listed below because they were found to contain drugs.

  • Mezo is sold on various websites and in some retail stores. It was found to contain benzylsibutramine, a substance structurally similar to sibutramine.
  • Best Line Suplemento Alimenticio Capsules are sold on various websites and in some retail stores. It was found to contain sibutramine.
  • Sibutramine, the active ingredient in the obesity drug Meridia, was removed from the U.S. market in October 2010 because it can substantially increase blood pressure and pulse rate in some individuals, and may present a significant risk for patients with a history of coronary artery disease, congestive heart failure, arrhythmias, or stroke. This drug may also interact, in life-threatening ways, with other medications a consumer may be taking.

  • LX1 is sold on various websites, including Dr. Skin Secrets, and possibly in some retail stores. It was found to contain undeclared DMAA.
  • Dietary supplements containing DMAA (also known as 1,3-dimethylamylamine, methylhexanamine or geranium extract) are illegal. The chemical has been linked to a number of serious adverse effects, including narrowing of blood vessels and arteries, and increased risk of elevated blood pressure, shortness of breath and heart attack.

Consumers who have purchased these supplements should discontinue use immediately and contact their healthcare provider if they have experienced any adverse side effects. Consumers and healthcare providers are also encouraged to report any adverse reactions to the FDA's MedWatch Adverse Event Reporting Program.
