Consumers should not purchase or use XtraHRD, a dietary supplement sold as a sexual enhancement treatment on various websites, including www.amazon.com, and in retail stores, because it contains a hidden drug ingredient, the Food and Drug Administration (FDA) warned in a safety communication.
Laboratory analysis confirmed that XtraHRD contains N-desmethyl tadlafil, an analogue of tadalafil, the active ingredient in the prescription erectile dysfunction drug Cialis. This undeclared ingredient may interact with nitrates found in some prescription drugs such as 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 after taking this sexual enhancement drug should be reported to the FDA MedWatch Adverse Event Reporting Program at www.FDA.gov/MedWatch/Report.htm.
The FDA issued the warning to inform the public of a growing trend in dietary supplements and conventional foods with hidden drugs and chemicals that can pose risks to consumers. These products are typically promoted for sexual enhancement, weight loss and body building and are often represented as “all natural.”
The agency is unable to test and identify all products marketed as dietary supplements that may have potentially harmful hidden ingredients. As a result, consumers are advised to use caution before purchasing any dietary supplement, particularly those for weight loss, sexual enhancement, or athletic performance including body building.
