I had a reaction to the fillers in my Budesonide which was manufactured by Perrigo. I went to many pharmacies trying to find a different brand. I finally found a small local (unchained) pharmacy who agreed to order the Budesonide made by Amneal. Never had a problem since. However, you might also want to know, that once I tapered down to just 3mg a day, my rheumatologist switched my rheumatoid arthritis drug to Xeljanz and within 2 wks, I no longer needed the Budesonide at all. I have collagenous microscopic colitis. I take soluble fiber capsules each morning, along with colestipol since I no longer have a gall bladder. I still have to be careful about what I eat and when, but I rarely have diarrhea anymore. I still take generic prilosec for GERD, but I stopped the Nsaids for pain. I rely on tylenol and tramadol now. Lots of folks have more than one autoimmune issue. I hope that things improve for you. Good luck
