There are a bunch of drugs that all metabolize a bit differently, and some may be the same but called different names depending on where you are. 6MP, Imuran, mecapapurine, Azaithioprine. I'm not sure if there are others that also go under this heading. They are immuno-suppresants. I have been on 6MP for probably close to a decade. It can have some serious side effects, especially at very high doses (it is used for cancer patients at much higher doses than CD patients) I have not had any side effects from it. You will need to have blood work done on a regular basis, to check your liver levels and to make sure you are at the correct dosage. Once you have been on it for a while, they will scale back the frequency of the blood tests. You can do a search and go through some of the older posts. Some people have had very good results, others have had bad reactions and others it has helped but not been a miracle drug. Like everything else with CD, it all depends on the individual.
