I've been told that there are some medications and drugs that should be avoided when you have Crohn's. By own experience I know that "kill-all-bacteria"-penicillin is a bad bad idea, and if you must have penicillin or antibiotics it should be one that is aimed specifically at the bacteria you have and need to get rid of. Also I know that diklofenac (don't know if it's called this in English) should be avoided, and possibly also NSAIDs like Aspirin (but I don't know if all NSAIDs are "bad"). Anyone else who have something to add to the list? Vitamins or supplements that should be avoided?
