I recently started amitriptyline for nerve pain. I started on 10mg, had no marked side effects, but it wasn’t effective. The doctor told me to increase to 50mg. That seemed too much of a jump to me, so I self administered 25-30mg for about 1-2 weeks. It was during that period that I started experiencing stomach pains and diarrhea. I did try the 50mg for a few days, but I contacted the doctor due to the discomfort. He told me to go back to the 10mg and see if it helped. I did that for about a week, but the side effects continued. At that point, I stopped taking the medication altogether. It has been at least a week since discontinuing the medication, and I am still experiencing the stomach pain and some diarrhea. I’m just wondering if anyone else has had this side effect. I’m also concerned about how long it is taking to subside. I have decided to go see my PCP to rule out any other causes, but this did not occur until I started taking amitriptyline.
