rheumatoid arthritis
"I had first infusion with no problems during administration but 2 weeks after I had to go to the E.R. with a heart arrhythmia and had to have my heart shocked back into normal rhythm. Two days later had second infusion with no problems during administration. 2 weeks later same thing...back to the E.R....heart shocked back into rhythm . Heart rate was stuck at 150 bpm. Had to be put in hospital for 4 days to be given an anti - arrhythmic drug that can also cause a fatal arrhythmia. So I would be cautious if you have any type of heart problem prior to taking Rituxan. I will not ever take it again."
