The Food and Drug Administration (FDA) is warning consumers not to purchase or use Man of Steel, Man of Steel 2, or Super Panther 7K dietary supplements marketed for sexual enhancement because the products contain hidden drug ingredients that pose a risk to human health. The products are sold online at various websites and in some retail stores.
Laboratory analysis conducted by the FDA confirmed that Man of Steel and Man of Steel 2 contain sildenafil, the active drug ingredient in the prescription erectile dysfunction medication Viagra. Super Panther 7K 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.
“This notification is to inform the public of a growing trends of dietary supplements or conventional foods with hidden drugs and chemicals,” the FDA said in a public notice. “These products are typically promoted for sexual enhancement, weight loss, and body building and are often represented as being ‘all natural.’ FDA is unable to test and identify all products marketed as dietary supplements that have potentially harmful ingredients. Consumers should exercise caution before purchasing any product in the above categories.”
