Started finasteride a month ago, at first I was also worried about the sides but one day after a few drinks I went nuts and took my first pill.
Apart from the occasional testicle aches for the first few days I have had no other sides at all! After a week's treatment I am no longer seeing any hair on my pillow where prior to finasteride I would see at least 15 on my pillow.
May I ask what dose you are on?
