Three Weight Loss Supplements Found to Contain Drugs

The FDA recently warned consumers not to buy or use the following weight loss supplements because they were found to contain undeclared drugs. Each was identified during an examination of international mail shipments.

Click the name of each product below to see the FDA warning:

  • On February 27, 2015 the FDA warned consumers that Botanical Slimming was found to contain fluoxetine.
  • On March 3, 2015 the FDA warned consumers that Diablos Eca Fire Caps were found to contain sildenafil, phenolphthalein, sibutramine and an analogue of sibutramine, deisobutylbenzylsibutramine.
  • On March 5, 2015 the FDA warned consumers that Black Mamba Hyperrush was found to contain sibutramine and phenolphthalein.

Fluoxetine is an FDA approved selective serotonin reuptake inhibitor (SSRI) drug prescribed to treat depression, anxiety, and other conditions. SSRI drugs are associated with serious side effects including suicidal thinking, abnormal bleeding, and seizures, and can interact with other common medications such as aspirin and ibuprofen, which can cause ventricular arrhythmia or sudden death.

Sildenafil, the active ingredient in the prescription drug Viagra, is typically prescribed for erectile dysfunction. This drug can cause symptoms like headache and flushing, and can interact with medications containing nitrates such as nitroglycerine, resulting in dangerously low blood pressure.

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.

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 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.
