So I've have two Remicade infusions so far, both were really easy. I felt great after my first infusion and my upset stomachs had basically gone away. However after my second infusion my stomach was a wreck again. I went to see my doctor and she said that I possibly could have developed antibodies or I just might need a stronger dose. I'm having the Prometheus test done but not for about 3 weeks. I just got used to the idea of Remicade and I don't want to switch to Humira, it freaks me out, but I guess I will have to if Remicade doesn't work for me. Does anyone have experience with this or know if this sounds like antibodies or just that I need a stronger dose?? I would really appreciate any insight as I am a Crohn's and Remicade newbie.. thanks :/
