My Long Covid issues included chronic diarrhea which became worse of the course of 5 months. I felt like I couldn’t leave the house for fear of having a soiling my pants unless I took Immodium AD. My GI doctor prescribed Xifaxan for 2 weeks because she said that sometimes remnants of the virus do not flush out of the body completely. Remnants can hang out in the intestines and wreak havoc. After the course of Xifaxan, I felt like a new person. Then I got Covid again, and had a relapse of diarrhea. I did stool samples just to be sure it wasn’t C-diff or parasites. The tests came back negative, so my doctor prescribed a 2nd course of Xifaxan, and that cleared up the diarrhea.
