Has this happened to anyone else? I was on Remicade for a few years when I had a few allergic reactions and was pulled off. Then I was placed on humira 40 mgs every other week, when that wasn't cutting it I was bumped to every week. I had a recent colonoscopy which showed I was still raw and ulcerated on the left side of my colon so a blood test was ordered to check my humira levels. The results came back and there's enough drug in my system bit no detectable antibodies...basically I've failed all tnf blockers. I'm to try entivyo next but after that there's no other approved drug to treat inflammatory bowel disease. I'm burning through drugs like there's no tomorrow. Can someone tell me a little about entivyo, how long the infusions take? The side effects (will I feel worn out after them like I was on Remicade)?
