I was on 6mp for about
a year, but stopped it because it wasn't helping and my liver enzymes were elevated, and we knew it could be from the 6mp. I didn't have any hair loss or any other side effects other than the liver enzymes. I wasn't on folic acid with the 6mp, but took it with methotrexate and didn't have any hair loss with that either.
I took stool softeners for a while, and then just resorted to taking them when I really had to, because I'm on so many other meds. I've tried dulcolax, but it gives me horrible intestinal pains. The stuff I used before was the generic Walmart stool softener and it didn't seem to bother me.
