The FDA is warning consumers not to purchase or use O.M.G., a product marketed for sexual enhancement.

FDA laboratory analysis confirmed the undeclared presence of sildenafil in the supplement. Sildenafil is the active ingredient in Viagra (sildenafil citrate; Pfizer), an FDA approved drug used to treat erectile dysfunction. Sildenafil may interact with nitrates found in some prescription drugs such as nitroglycerin; this may result in lowered blood pressure to dangerous levels. Nitrates are often taken by male patients with diabetes, high blood pressure, high cholesterol, or heart disease.
