Dangerous Hidden Ingredient in Sexual Enhancement Product

The sexual enhancement product, S.W.A.G., contains a hidden ingredient, sildenafil, the active ingredient in Viagra®, which could present serious health risks when mixed with ingredients in other prescriptions drugs according to the warnings in an FDA public notice. The FDA has instructed consumers to discontinue use of and dispose of the product as it could lower blood pressures to dangerous levels. The FDA also encourages consumers who have used the product to consult with health care providers as soon as possible and to report any negative side effects to the FDA’s MedWatch Safety Information and Adverse Event Reporting Program. This warning follows other general FDA announcements about concerns over fraudulent dietary supplements with hidden ingredients or deceptive labeling.


S.W.A.G. is promoted and sold as a sexual enhancement product on various websites including the website www.SexWithAGrudge.com. According to the FDA, the product contains an undeclared ingredient, sildenafil, which is the active ingredient in drugs used to treat erectile dysfunction, such as Viagra that are subject to FDA approval. The FDA warns that the sildenafil may lead to dangerously low blood pressure if it interacts with other prescription drugs containing nitrates, such as nitroglycerine and other drugs that treat high blood pressure, high cholesterol or heart disease.

Dietary Supplements

Previously, the FDA issued a general warning for fraudulent dietary supplements, including those promoting weight loss, sexual enhancement, and bodybuilding. The FDA reported that it had discovered over 300 products that contained either hidden ingredients or deceptive labeling that mislead consumers as to the true composition of the products. The FDA stated that such products were, “masquerading as dietary supplements” and contained “hidden prescription ingredients at levels much higher than those found in an approved drug product.” As a result of consumer use of these products, the FDA has received reports of stroke, liver injury, kidney failure, heart palpitations, and death.

Consumer Actions

While the FDA strongly recommended individuals that have used S.W.A.G. to seek medical guidance and to report side effects or adverse reactions to the MedWatch program, it also issued general guidelines as to how consumers may protect themselves from products such as these in the future. In order to raise consumer awareness and allow for the easy identification of dangerous products, the FDA suggested that consumers avoid products (1) claiming to be alternatives for FDA-approved drugs and anabolic steroids; (2) that are marketed in another language; (3) that contain claims promising rapid effects; (4) and that include warnings that the product causes positive outcomes in performance enhancement drug tests. When considering the use of a product that is promoted as a dietary supplement, the FDA suggests consultation with a medical provider and visiting the FDA website.
