Audience: Consumers, Family Practice

Issue: Magic Power Coffee, an instant coffee product marketed as a dietary supplement for sexual enhancement, contains the drug ingredient hydroxythiohomosildenafil, a chemical similar to sildenafil, the active ingredient in Viagra. Hydroxythiohomosildenafil, like sildenafil, may interact with prescription drugs known as nitrates, including nitroglycerin, and cause dangerously low blood pressure. FDA is warning consumers not to use this product.

Background: The product is distributed on Internet sites and online auctions by multiple independent distributors participating in an online multi-level marketing scheme. It is sold in a 2-serving box and a 12-serving carton containing six 2-serving boxes.

Recommendation: Consumers who have Magic Power Coffee should stop using it immediately. The FDA advises consumers who have experienced any negative side effects from sexual enhancement products to consult a health care professional and to safely discard the product.
