The Food and Drug Administration (FDA) is warning consumers not to purchase or use certain dietary supplements marketed for sexual enhancement because the products contain hidden prescription drugs that can be harmful. The products are sold online at various websites and in some retail stores.
Laboratory analysis conducted by the FDA confirmed that supplements contained the active drug ingredient in the prescription erectile dysfunction medication Viagra. The supplements named in the FDA’s public notification include Monster X 1350, Love Zen 3000, Royal Master 1500, Macho Man 3000, and Own the Knight 1750.
The supplement Xzone Gold was found to contain sildenafil and tadalafil, the active ingredient in the prescription erectile dysfunction drug Cialis.
Undeclared sildenafil and tadalafil may interact with nitrates found in some prescription drugs, such a nitroglycerin, and may lower blood pressure to dangerous levels. Men with diabetes, high blood pressure, high cholesterol or heart disease often take nitrates.
Any adverse events experienced while taking these products should be reported to the FDA MedWatch Adverse Event Reporting Program at www.FDA.gov/MedWatch/Report.htm.
The FDA issued the public notification along with a warning about a growing trend in dietary supplements or conventional foods containing hidden drugs that in some cases can be harmful to health. The products are typically promoted for sexual enhancement, weight loss and body building.
“FDA is unable to test and identify all products marketed as dietary supplements that have potentially harmful ingredients,” the agency said. “Consumers should exercise caution before purchasing any product in the above categories.”
