I was diagnosed with ulcerative colitis in February. However after another doctor performed a second colonoscopy, I was diagnosed with Crohn's. I spent 7 days in the hospital and was given an injection of Remicade. It went well and I was released. When the next injection was due I had a severe allergic reaction and treatment was stopped only 20 minutes into it. My doctor took precautions the next time, but I still had an allergic reaction. The next week my doctor had it approved for me to get Entyvio. I had no problem with this medication. Yesterday I had my second dose. Everything went well. I am not sure, but I haven't seen many people on this medication yet. I felt a little better a week after my first dose. I was just wondering has anyone had Entyvio, and how long it took to feel good?
