Hello,
I recently renewed my Propecia prescription after being off the medication for nearly two years. I didn't experience any side effects then; however, the day after I took the medication, I experienced some rectal bleeding. The bleeding stopped after a day later; however, I've constipated ever since I started retaking the medication. While I left a message with my doctor regarding this possible coincidence, I plan to schedule an appointment for a colonoscopy.

Aside from the sexual side effects (decreased libido), has anyone experienced any of the side effects I reference above? I would appreciate any feedback you can provide me. Many thanks in advance.
