FDA notified consumers and healthcare professionals that Vigor-25, a product marketed as a natural dietary supplement to enhance male sexual performance, should not be purchased or used because it contains sildenafil, the active ingredient in the prescription drug Viagra.
Sildenafil may interact with prescription drugs known as nitrates, including nitroglycerin, and can dangerously lower blood pressure. The FDA is investigating the reported death of a 26-year old man, possibly associated with the use of Vigor-25.
BACKGROUND: Vigor-25, distributed by Piston Corp., is sold on Internet sites and possibly in some retail outlets. FDA has found many products marketed as dietary supplements for sexual enhancement during the past several years that can be harmful because they contain active ingredients in FDA-approved drugs or variations of these ingredients. Sexual enhancement products promising rapid effects (e.g., claim to work in minutes to hours) or long-lasting effects (e.g., claim to last 24-72 hours) are likely to contain a contaminant.
