I had no reactions, they say many don’t! Be prepared that it will take a few infusions to get your body all up & ready, I think it’s like week 0,2,4,6 & then you will be every 8 weeks. Remember to tell your nurse at the hospital & your dr how you are feeling once you get to week 8. Personally I was having colon discomfort starting at week 7, so they changed me to every 7 weeks now vs 8. I’ve been on it for 10 months. I recently just had a flare (I was traveling….of course), so expect that it may take upwards of a yr from what I understand to really help to get me into remission as much as possible.
Hope you have as much relief as I do with Entyvio!
