FDA Public Notifications Warn Consumers of Dangerous Supplements

FDA Public Notifications Warn Consumers of Dangerous Supplements
December 17, 2015

The Food and Drug Administration (FDA) has announced two new public notifications which urge customers to avoid use of certain supplements.

FDA lab tests found that the supplements, Power Tiger-X and Thirty Plus, contain medications that have either been removed from the market for safety reasons, or are prescription medications that are not approved for use as a supplement ingredient.

Power Tiger-X, an erectile dysfunction (ED) supplement, contains sulfoaildenafil. This substance is structurally similar to sildenafil, the active ingredient in Viagra. This undeclared ingredient may interact with nitrates found in some prescription drugs such as nitroglycerin and may lower blood pressure to dangerous levels. Men with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates.

Consumers could purchase Power Tiger-X on various websites, including everestwholesales.com, and in some retail stores.

Next, the FDA is recommending that consumers steer clear of Thirty Plus, a product promoted and sold for weight loss because it contains sibutramine. Sibutramine is known to substantially increase blood pressure and/or pulse rate in some patients and may present a significant risk for patients with a history of coronary artery disease, congestive heart failure, arrhythmias, or stroke. This product may also interact, in life-threatening ways, with other medications a consumer may be taking. Sibutramine was removed from the market in October 2010.

Thirty Plus was sold on various websites, including getskinny.bigcartel.com, and in some retail stores.

The FDA encourages health care professionals and patients to report any adverse effects related to the use of these products. To report information, complete the MedWatch Online Voluntary Reporting Form.
