I am digging way back to answer your question... Roughly 15 yrs ago, when I was 6 months post takedown, I was given an antibiotic course (I believe amoxicillin) for some mild cough. I was doing great with my new pouch up to that point. Within a few days after finishing antibiotic course, I developed first case of pouchitis. This has become a chronic condition that has only been contolled via Cipro ever since. Is my onset a coincidence? Would I have developed poichiris anyway? I can only guess - my "gut" says I would have developed it at some point anyway, but truth will always remain a mystery.
Currently thinking about other options since Cipro is (finally) seemingly losing its punch.
