BETHESDA, Md. — The Food and Drug Administration on Thursday advised consumers not to purchase or use three separate sexual enhancement products that are being promoted as dietary supplements because they contain undeclared and unapproved prescription-only ingredients.
The three products include Libido Sexual Enhancer, a product promoted and sold for sexual enhancement on various web sites, including www.vegasredpleasure.com; Rock-It Man, a product promoted and sold for sexual enhancement on www.shopinprivate.com and in some retail stores; and Stiff Days, a product also promoted and sold both online and in stores.
FDA laboratory analyses of the three medicines confirmed that they contain ingredients such as sildenafil, the active ingredient in the FDA-approved prescription drug Viagra, used to treat Erectile Dysfunction. "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," the agency advised.
