I had my Rituximab infusion on 10/14 and 10/15. The nurse administered premedication of Benadryl and Tylenol prior to the infusion start. About 20 minutes into the Rituximab infusion which was started at a very slow rate, I began having shortness of breath and upper chest pressure. I was also very flushed my nurse told me. I was given O2 via nasal cannula and an IV cortisone of some sort. They restarted the medication again after about 15 minutes and the same thing happened although not to the same extent. At that point, they decided to give me some IV Demerol to assist with my infusion. I was only given a third of the medication on the first day. I returned the next day for the rest of the Rituximab and there were no side effects at all. The nurse who took care of me both days also gets Rituximab infusions so that was very helpful to have his perspective. My next infusion is on October 21st.
