Dietary Supplements Promoted for Sexual Enhancement

Audience: Consumers and healthcare professionals

[Posted 07/13/2006] The FDA notified healthcare professionals and consumers of a warning not to purchase or consume Zimaxx, Libidus, Neophase, Nasutra, Vigor-25, Actra-Rx, or 4EVERON, illegal drugs with undeclared ingredients that are promoted and sold on web sites as "dietary supplements" for treating erectile dysfunction and enhancing sexual performance. These products have not been approved by FDA, and there is no guarantee of their safety and effectiveness, or of the purity of their ingredients. They pose a threat to consumers because the undeclared ingredients may interact with nitrates found in some prescription drugs (such as nitroglycerin) and lower blood pressure to dangerous levels. Consumers with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates. FDA advises consumers who have used any of these products to discontinue use and to consult their healthcare provider.
