Hello, I have been using propecia for about 10 months. The last two months I took only half of the pill, because i had more headaches, testicle and stomach pains, dizziness and lower sex drive. My hair loss has stopped and i dont see any loss when i pull my hair. My question is how will this half pill effect on my hairloss? Should i expect the same results or can my situation worsen badly? And can propecia, if i take it for a long time, really stop balding or does it only slow the process (for how many years for example)? thanks

Taking half pill of Propecia is reported to be about 70% effective as taking a full dose of Propecia. I cannot tell you how taking half a pill will change your hair loss/gain, but it is certainly better than not taking at all. In your particular case, it seems to be a good compromise, although some of your complaints should not be caused by this drug.
