The U.S. Food and Drug Administration (FDA) warned consumers not to buy or use weight-loss supplements Natural Body Solution and Slim Trim U after they were found to contain sibutramine. Both products are sold on various websites and in some retail stores.

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.

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

• Complete and submit the report online: www.fda.gov/medwatch/report.htm
• Download the form or call (800) 332-1088 to request a reporting form, then complete and return to the address on the pre-addressed form, or submit by fax to (800) FDA-0178.
