Hi, Is there any conclusive evidence that the regular use of Finasteride (Propecia) for hair loss can result in Gynocomastia as a side-effect?
The Physician’s Desk Reference does not list this drug as a possible cause of Gynocomastia, but I have heard mixed stories from individuals.
Results of any known conclusive studies in this regard would be appreciated.
Gynecomastia is a known side effect from the use of Propecia. I do not understand the mechanism of action for it, but when it does happen, most men usually find it as a reason to stop using Propecia. Fortunately, I believe that the incidence is well below 1 in 300 men. I don’t know of any studies off the top of my head, but if any blog readers happen to have a link to any studies posted online, please feel free to post the link in the comments.
