I’m so sorry that you’re going through chronic Pouchitis. I have that also but usually my cocktail of ... Cipro, Lomotil, Imodium and a medical probiotic called Visbiome helps me remain stable. This is prescription strength probiotic.
I stay on a maintenance dose of 500 mg. Of Cipro but when I flare I increase to 1000 then taper back.
Good Luck and feel better!
