Undeclared Drugs Found in Two Weight Loss Supplements

On July 2, 2015 the FDA warned consumers not to buy or use weight loss supplements listed below because they were found to contain undeclared drugs. Click on the name of each product to read the full warning.

  • ZeroXtreme Capsules are sold on www.zeroxtremeusa.com and in some retail stores. They were found to contain sibutramine and desmethylsibutramine.
  • Akttive Capsules are sold on www.akttive.com and in some retail stores. They were found to contain sibutramine, desmethylsibutramine, and phenolphthalein.

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. Desmethylsibutramine is a substance similar to sibutramine.

Phenolphthalein, once an ingredient in some over-the-counter laxative products, was reclassified by the FDA in 1999 as "not generally recognized as safe and effective."  

Consumers should not use these supplements, 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.
