Sulfasalazine
"I've only been taking this for 2 1/2 weeks but I'm very impressed that my chronic loose stools have completely stopped! I've noticed no negative side effects and if mild constipation is a side effect, I welcome it. I am now taking a little less loperamide and I'll be experimenting to see if increasing dosages of sulfasalizine will enable me to take even less loperamide. Later I'll get blood tests to make sure the new drug isn't having negative effects that I don't notice. After all these years dealing with diarrhea, I'm so grateful my doc suggested I try this stuff!"
