I'm guessing that b/c it's topical, it's not going to affect UC very much. However, it'd be a completely different story if it was taken orally.
My dermatologist prescribed topical Climydacin (sp?), which has a side effect of pseudomembraneous colitis. But he said that the topical will be safe.
But I'm paranoid, so I haven't used it yet.
