Actra-Rx and Yilishen

Audience: Consumers and healthcare professionals

The FDA warned consumers not to purchase or to consume Actra-Rx or Yilishen, two products promoted and offered for sale on Web sites as "dietary supplements" for treating erectile dysfunction and enhancing sexual performance for men. 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. Consumers who have taken Actra-Rx or Yilishen should stop taking it and consult with their health care providers regarding erectile dysfunction treatment.

[UPDATE December 1, 2004 - Recall Notice - Lot number Actra-Rx 001-3 recalled]
