My last infusion was 2 weeks ago. On Saturday I started breaking out in hives, by today I was itchy all over and my neck and face turned red at one point but I had just taken Benadryl so it went away fairly quickly. The pharmacist said something like this could happen a week or two after the infusion, but I'm curious if anyone else has actually experienced this or should I suspect something else. The only other meds I am on are Entocort (tapering, down to 3mg per day) and BC.
