has several users declaring erectile dysfunction problems.

It seems that Merck has been aware for a while that their highly successful hair loss treatment has a worrying drawback. It has adverse problems which could cause permanent erectile dysfunction. Not only were consumers not properly informed of all the potential side effects, but also the medical practitioners prescribing the medication. As there are not at present any recognised tests in order to confirm erectile dysfunction, blood tests can be done to rule out any other ailments that might be the cause of the impotence.

A considerable amount of fit and healthy men are relating problems with their sex life, whilst on a course of Propecia. Unfortunately the medications advice label does not warn that the damaging effect, will not cease when medication is halted. Packaging information in America has indications on it, that taking Propecia could have a link to erectile dysfunction, but there are suggestions that sexual problem will clear up.

There are several cases being bought to light that the impotence issue is not resolving itself and becoming long lasting, which is leading to infertility, amongst other sexual issues. Even though misinformation has occurred on warning labels in the United States, in 2008 Merck amended their erectile dysfunction information on packaging in other countries, this includes UK and Japan. The change in advice was that discontinued use of Propecia could still see the inability to maintain an erection and it leading to become a continual problem.
