Propecia Users Take Note - PSA Test Scores Affected

Researchers conclude that the hair-loss drug Propecia lowers the reading on the PSA prostate-cancer screening test. Therefore, men on Propecia may have dangerously high PSA levels even if their test scores are in the normal range according to the research study from Anthony V. D'Amico, MD, PhD, of Brigham and Women's Hospital, and Claus G. Roehrborn, MD, of the University of Texas Southwestern Medical Center.

It is known that Proscar affects the PSA test. Propecia is a low-dose version of Proscar. This suggests that men on Propecia may have an unseen problem.

The D'Amico/Roehrborn study appears in the early online edition of The Lancet.
