Propecia Side Effects

The manufacturers of Propecia (Merck ) reported potential side effects of Propecia usage, however, recent studies have shown that the extent of those potential side effects may have been grossly under reported. 



Merck reported that side effects of finasteride include impotence (1.1% to 18.5%), abnormal ejaculation (7.2%), decreased ejaculatory volume (0.9% to 2.8%), abnormal sexual function (2.5%), gynecomastia (2.2%), erectile dysfunction (1.3%), ejaculation disorder (1.2%), testicular pain and recently, depression was added to that list.  According to the product package insert, these side effects went away when men discontinued therapy with Finasteride due to these side effects and in most men who continued therapy – HOWEVER – recent research shows that this is not the case. Propecia can cause impotence

In March of 2011, Dr. Michael Irwig from George Washington University published his study on persistent sexual side effects from Finasteride (Propecia) in young men aged 21-46.  The study, published in the Journal of Sexual Medicine, reveals that finasteride can cause persistent sexual dysfunction, including low sexual desire, erectile dysfunction and problems with orgasms.  Subjects also reported new-onset persistent sexual dysfunction associated with the use of finasteride:  94% developed low libido, 92% developed erectile dysfunction, 92% developed decreased arousal, and 69% developed problems with orgasm.

European warnings about Propecia side effects have been updated to warn of the possibility for permanent sexual dysfunction, however, the warnings remain unchanged in North America and currently state that sexual side effects are reversible.

Propecia Impotence

Many Propecia users have reported continued diminished libido or erectile dysfunction, even after stopping the drug.   Other countries have taken strong actions to warn users of Propecia side effects:  In December 2008, Sweden concluded a safety investigation of finasteride and subsequently advised that the use of finasteride may result in irreversible sexual dysfunction.  The United Kingdom reported that erectile dysfunction persistance once use of finasteride has stopped has been reported to them, and the Italian government has also made similar label changes warning of the reported irreversible sexual dysfunction.
