My 16 year old son has Crohns. He was diagnosed when he was 12. He has been on Remicade for 2 years now he gets it every 4 weeks rather then the norm of every 8 weeks. He's is okay but still has some bad days. My dr informed me today that she wants to stop Remicade and start prednisone then Imuran. My instincts are telling me that this is not a good idea due to the fact that Imuran takes a few months to work and if he feels good more often then he feels sick why change things so drastically. Any advice?
