I've been on Entyvio for a year and a half or more, and for the most part I'm pleased with it. I have a lot less psoriasis for one thing. But occasionally even when I'm avoiding my triggers I get diarrhea. And then it stays around. A while back I tried Imodium to stop it and it did amazingly well. Now there are times when I take it once or twice a week just to stay away from the bathroom. Is this Entyvio not doing it's job?? Is there any problem with taking Imodium this frequently??
