Hi Sassysback. I am on Mezavant, but not Entyvio. I've never received infusions for anything. I just take Mezavant pills.
My GI wants me to go on Prednisone, but I want to try retention enemas of some kind. We are in a stalemate right now, but we'll see how the next round in the battle goes.
So unfortunately I am not of any help to you with your questions about
infusion clinics or side effects. (Oh, if you were asking about
side effects from Mezavant, I have had none).
Good luck with it all!! Maybe someday I'll be asking for your advice.
