Herbal Supplement Warning

FDA warns against use of sexual enhancement herbal supplement.
The Time (12/13, Melnick) "Healthland" blog reported, "If the name weren't enough to put you off the stuff, the Food and Drug Administration (FDA) has a health-related reason to stop taking Man Up Now: the sexual enhancement herbal supplement contains a variation of the active ingredient in Viagra, and could dangerously lower your blood pressure." The FDA "analyzed Man Up Now and determined that it contains sulfoaildenafil, a chemical similar to sildenafil, the active ingredient in Viagra." This chemical "may interact with prescription drugs such as nitrates, including nitroglycerin, and cause dangerously low blood pressure." The CNN (12/14) "The Chart" blog and the NPR (12/14) "Shots" blog also report the story.
