Hello Dr. I started taking Propecia 1mg daily for about three months now. I am 39 years old, and just started thinning a little bit. My hair is really important to me. My doctor said that propecia could help. I have seen a difference already. However I have noticed that I have developed a little bit of ED. It just seems to take a little longer to achieve. I really don t want to come off the propecia. Can you give me any suggestions, would a smaller dose, or every second day cut the side effects?? Is there also something more natural, that would work the same? I am in good health, and really don t like to take medication. But I thought I would try the propecia for a few years. I really miss the thick hair I use to have, and how fast it use to grow. It is too bad the side effects have to be this. The drug seems too good to be true. Thank you Dr. for your time. Have a nice day.
