WASHINGTON, Nov. 5 (UPI) -- The U.S. Food and Drug Administration has issued a warning about a sexual enhancement dietary supplement found to be contaminated.
The FDA said "Stiff Nights," a product marketed as a dietary supplement for sexual enhancement, contains an illegal ingredient that can dangerously lower blood pressure.
"In the case of Stiff Nights, following a consumer complaint, the FDA determined that the product contains sulfoaildenafil," officials said in a statement "This is a chemical similar to sildenafil, the active ingredient in Viagra. Sulfoaildenafil may interact with prescription drugs known as nitrates, including nitroglycerin, and cause dangerously low blood pressure."
Stiff Night is distributed on Internet sites and at retail stores by Impulsaria LLC of Grand Rapids, Mich. It is sold in bottles containing 6, 12 or 30 red capsules or in blister packs containing one or two capsules.
"Because this product is labeled as an 'all natural dietary supplement,' consumers may assume it is harmless and poses no health risk," said Deborah Autor, director of the FDA's Center for Drug Evaluation and Research Office of Compliance. "In fact, this product is illegally marketed and can cause serious complications."
The FDA advises consumers who have experienced any adverse events from sexual enhancement products to consult a health care professional. Consumers should report adverse events to the FDA's MedWatch program at 800-332-1088 or online at www.fda.gov/medwatch/report.htm.
