Fatigue is a big part of RA (or any autoimmune disease for that matter), but could be in part related to the Rituxan as well. As Don suggests, many people with RA also have anemia, Rituxan can worsen this. I presume that your rheumatologist is monitoring your blood work routinely, so new or worsening anemia should be caught promptly and addressed.
I also take Rituxan (along with MTX, sulfasalazine, prednisone, Plaquenil and others) and find that I have a good deal of fatigue following infusions despite receiving 200mg of solumedrol and 10mg of dexamethsone (steroids) with each. I break out in blisters and hives, and get rigors during the infusions, so I tend to get more steroids than some people.
Luckily, I was aware that this was a possibility before I started Rituxan, so I was not alarmed. I am also a former heme-onc RN prior to moving to critical care several years ago, and have given Rituxan a thousand times to patients with lymphoma, so I was pretty familiar with the side effects before I got my first dose. Most people notice fatigue after receiving Rituxan. Dizziness, weakness, and nausea are also pretty common, although some people are lucky and completely escape the nausea. Bone pain and flu-like symptoms are quite common post infusion as well.
I try to schedule my infusions around my work schedule. I find that the nausea kicks in about day 4 -5 for me and persists for a couple of weeks and then lets up. The fatigue is bad the first week as well, but gets better (at least for me) after the first week. The 2 days following infusion, I have pretty bad bone pain and lots of trouble sleeping. Low grade fever is common, and I have this as well. about a week after infusion, I am able to go back to work, although the 13 hour shift is a long one for me now. Never use to be, but after RA it is. I am only 45 and was an avid runner before RA. But things change, and I consider myself lucky to still be able to do a job that I love.
I hope this finds you feeling better. Good luck with your next infusion. If you have excessive fatigue or bleeding, bruising more than usual, make an appointment with your rheumatologist.
