The U.S. food and drug safety watchdog warned Thursday that an over-the-counter men's sex aid, labeled as all natural, contains a chemical similar to the active ingredient in Viagra and could be dangerous.
"Stiff Nights, a product marketed as a dietary supplement for sexual enhancement, contains an ingredient that can dangerously lower blood pressure and is illegal," said a statement from the Food and Drug Administration (FDA).
The FDA began probing Stiff Nights after receiving a customer complaint about the product.
The investigation found that rather than being all natural, Stiff Nights contains sulfoaildenafil, a chemical similar to the ingredient in Viagra.
"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," she said.
Sulfoaildenafil could interact with prescription drugs known as nitrates and cause dangerously low blood pressure.
Stiff Nights is sold online and at retail stores in bottles or blister packs containing red capsules.
A bottle of 12 Stiff Nights capsules was being offered Thursday on Amazon for around $27.
Another Web site — mystiffnights.com — said the product is made with "only the finest herbs and greens."
