I am a healthy 30yo male suffering from male pattern baldness. I am considering taking oral finasteride (1mg/day), but am concerned about potential side effects. I have heard bad reports that some side effects, particularly sexual side effects, can happen slowly without you really noticing until its too late. Some also report that these effects do not reverse following ceasation of the drug. However, it seems many people also have success with this treatment. What would your opinion be on this matter? Thanks. Dan.
