I have been diagnosed with Crohns in my small ileum and have been taking Prednisolone successfully for a few weeks. I'm starting to come down off the Pred and the consultant has put me onto Azathioprine. When I went to get the prescription from my doctor, he said he was very surprised that the consultant would put me on Azathioprine which is "old hat" with blood monitoring being required, rather than something more modern like Asacol. This has left me very confused. Does anyone know who I can actually trust?
