Most of us who receive Rituximab have a weakened immune system. So I’m not sure if that has a bearing on the possible reaction. Over the course of treatment though, your immune system could become more compromised but it should return to ‘normal’ when treatments end.

I’m sure you’re cautious already to avoid infections and illnesses. Wearing a mask out in public settings like restaurants, church, movies, planes…and of course hand sanitizers help reduce the possibility of illness.

It’s hard to tell what type of a reaction you might have to the Rituxan. My only side effect was with the initial fusion. I didn’t experience anything over the course of 4 weeks that I had the infusions except that the targeted inflammation on my spinal cord was successful!
Let me know how you do, ok?
