I am 22 and just diagnosed with Crohn's in April (although I had symptoms for about 5 years that were not diagnosed). I tried Pentasa and that didn't work. Then I went on Entocort, which seemed to work at first, but now all of my symptoms of Crohn's have come back and worsened. A month ago I started on Imuran, but I was told by someone that this drug should only be started when you are feeling better (ie when you have no/less symptoms) and that it can take 5-6 months to start taking effect. I am wondering if these things are true? and what people think of this drug and if anyone has had success with it? Thanks.
