@stan1357 Have you checked all of the websites that list side effects? Some don't list rare side effects. My immunosuppressant, sirolimus, seems to be causing one of the rare side effects - joint and muscle pain. I'm not entirely sure of that yet, I have three medications that can cause that, and I have managed to eliminate one from being the culprit and am in the process of eliminating another. I can't eliminate sirolimus so I just have to do it by process of elimination - the other two can be eliminated for brief periods.

I mentioned a while back in this stream that the immunosuppressants had caused lactose intolerance. That lasted for quite a few months but thankfully has gone away! I can now eat foods with lactose with no negative effects. I think when people have diarrhea from immunosuppressants that's the first thing they should look at, the possibility that it is lactose intolerance.
