Do not purchase or use Tiger 5000, a dietary supplement marketed and sold as a sexual enhancement in some retail stores and on various websites including Amazon.com, because a laboratory analysis has confirmed that it contains hidden sildenafil and tadalafil, the active ingredients in the prescription erectile dysfunction drugs Viagra and Cialis, respectively. Using these products may be hazardous to some consumers’ health, the Food and Drug Administration (FDA) warned in a Public Notification.
Undeclared sildenafil and tadalafil may interact with nitrates found in some prescription drugs like nitroglycerin and lower blood pressure to dangerous levels. People with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates.
The FDA conducts laboratory tests on dietary supplements that raise suspicion and oftentimes these products are ones marketed for sexual enhancement, weight loss or athletic performance such as bodybuilding. There is a growing trend for these products to contain hidden prescription medications or illegal drugs that can be harmful – and sometimes deadly – to consumers.
“Consumers should exercise caution before purchasing any products in the above categories,” the FDA said in the Public Notification.
Anyone who has taken Tiger 5000 or any dietary supplement and experienced side effects should seek medical attention. Any adverse events should be reported to the FDA MedWatch Adverse Event Reporting Program at www.FDA.gov/MedWatch/Report.htm.
