FDA Warning Regarding Counterfeit ExtenZe

May 27, 2011 8:58 am

FDA warns consumers about a counterfeit version of ExtenZe, a dietary supplement marketed for male sexual enhancement. The potentially harmful counterfeit product looks similar to the actual product, but contains tadalafil, or a combination of tadalafil and sildenafil, both active ingredients in FDA-approved prescription medicines for erectile dysfunction. These ingredients are not listed on the product label, and they may interact with other medicines, like the nitrates found in some prescription medicines 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. FDA advises consumers not to purchase any products labeled as “ExtenZe” with lot numbers 1110075 and F050899. Further, FDA advises consumers who have an ExtenZe product to check the lot numbers on the package to make sure they do not have a counterfeit product. Consumers who think they might have the counterfeit product should stop taking the product, and contact their health care provider if they are experiencing any negative side effects. More information is available in a FDA press release.
