Propecia and Erectile Dysfunction

An increasing number of men are reporting that they have suffered erectile dysfunction after using Propecia, a hair loss drug sold by Merck. Although it appears that the drug maker has known for some time that Propecia side effects may result in permanent erectile dysfunction and other sexual problems, they have failed to provide adequate warnings to consumers or the medical community in the United States. As a result, financial compensation may be available through a Propecia erectile dysfunction lawsuit.

Erectile dysfunction from Propecia involves the regular and repeated inability to obtain or maintain an erection. While there are no formal tests to reach an erectile dysfunction diagnosis, blood tests may be ordered to exclude other underlying disease that could be causing the erectile problems.

A large number of otherwise healthy, young men have reported experiencing sexual dysfunction after taking Propecia, and contrary to indication on the drug’s warning label, the problems may not stop even after the medication is no longer used.

While the warning label in the United States does indicate a possible connection between Propecia and erectile dysfunction, the information suggests that the problems resolved once Propecia is no longer used. However, that has proven not to be the case in multiple reports of Propecia problems submitted by users who have experienced long-lasting and often permanent inability to achieve or maintain an erection, as well as impotence, infertility and other sexual side effects.

Although misleading and incorrect information is provided on the Propecia warning label in the United States, Merck has updated the erectile dysfunction warnings as early as 2008 in other countries, including Japan, the U.K. and some other European countries. These warnings outside the United States inform users that some reports suggest that the erection problems after Propecia use may persist once the medication is discontinued.


The Propecia lawyers at Saiontz & Kirk, P.A. are investigating potential claims for men throughout the United States. Many men may be unaware that their sexual problems were caused by Propecia, but they could be left with permanent erectile dysfunction as a result of the medications side effects.
