For awhile I used antibiotics PLUS Budesonide ("designer" oral steroid) to treat pouchitis. Generally it isn't supposed to be a maintenance drug (although there are trials using budesonide as a maintenance drug for UC going on now), and I always flared when they tried to wean me off it (and they didn't want me on steroid suppositories long term either, due to concerns about thinning tissues).
Ultimately I switched to antibiotics PLUS Immuran and that combo is working well for me.
