Audience: Consumers and healthcare professionals
[Posted 01/25/2007] FDA and Ebek, Inc. notified healthcare professionals and consumers of a voluntary nationwide recall of the company's dietary supplement because the product contains tadalafil, a drug used to treat erectile dysfunction. Liviro3 is not approved by FDA to treat this condition. Tadalafil may interact with nitrates found in some prescription drugs and may lower blood pressure to dangerous levels.

Consumers with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates.

True Man and Energy Max Products
Audience: Consumers and healthcare professionals
[Posted 05/10/2007] FDA informed consumers and healthcare professionals regarding the dangers associated with the purchase or use of True Man or Energy Max products promoted and sold as dietary supplements throughout the United States. Both products, promoted as sexual enhancement products and as treatment for erectile dysfunction (ED), are illegal drug products that contain potentially harmful, undeclared ingredients.

Both Viagra and Levitra are FDA approved products for the treatment of ED. FDA has not approved True Man and Energy Max, therefore, the safety and effectiveness of these products are unknown. Consumers should discontinue use of these products and consult their healthcare professional about approved treatments for ED.

dietary supplement through mail orders and retailers located nationwide, and in
Puerto Rico, Canada, the United Kingdom, Russia, and China. The product was
recalled because it contained undeclared tadalafil, an FDA approved drug used to
treat male Erectile Dysfunction (ED). This poses a threat to consumers because
tadalafil may interact with nitrates found in some prescription drugs (such as
nitroglycerin) and may lower blood pressure to dangerous levels. Long Weekend is
not approved by FDA; therefore, the safety and effectiveness of this product is
unknown. Consumers should discontinue use of Long Weekend and consult their

FDA testing of Actra-Rx found that the product contained undeclared prescription-strength sildenafil. An interaction between sildenafil and certain prescription drugs containing nitrates (such as nitroglycerin) or nitrates found in illicit substances (such as amyl nitrate) may cause a significant lowering of blood pressure to an unsafe level.
