Sexual enhancement product Stiff Nights poses risks

Stiff Nights, a product sold as a dietary supplement for sexual enhancement, contains sulfoaildenafil, a chemical similar to sildenafil, the active ingredient in Viagra, according to a Food and Drug Administration warning today. Sulfoaildenafil poses a threat to consumers because it may interact with prescription drugs known as nitrates, including nitroglycerin, that are used by people with diabetes, high blood pressure, high cholesterol or heart disease. The chemical may also cause dangerously low blood pressure.

Stiff Nights is distributed on online and at retail stores by Impulsaria LLC of Grand Rapids, Michigan and is sold in bottles containing 6, 12, or 30 red capsules or in blister packs containing one or two capsules.

Take a look at the FDA’s list of sexual enhancement products to avoid, and if you’ve experienced adverse events from using any of the products, consult a health care professional and report it to the FDA's MedWatch program.
