I have kidney involvement with my Wegeners. I have had 2 of 4 treatments of Rituxan infusions. I am extremely fatigued and have shortness of breath and my cough has gotten worse. Sometimes its productive other times just a dry cough. Just developed watery and redness in my eyes 2 days ago. I think these are all side effects of the drug. Can anyone say if this goes away? If so, when should I expect to be back to somewhat normal. I was having a hard time working and decided to take time off, just not sure how long it will be.
