Rituximab side effects

Hi all had my rtx infusion yesterday when they had to give me double antihistamine due to reaction, last night I had a terrible night I was awake nearly all night with heart beating fast and fuzzy feeling in both arms, has anybody else noticed these side effects, I am due to have 2nd treatment in 2 weeks and this will be my 3 cycle overall but I can't remember these side effects last time 😩😩😩

  • Did you also have a steroid infusion with the ritux - for me the steroid would lead to a sleepless night. Farm

  • Yes I had the steroid before the infusion 🙂

  • I had difficulty sleeping for a couple of nights with some anxiety and racing heart , i think it was the steroids. I also had a couple of episodes of severe stomach pain which the nnurse said was probably due to steroids. If you are worried do phone the rheumy nurse . Hope you feel better🌷

  • Hi Debsy...I think you replied on my similar post 😊 I had the same...it's not a nice feeling at all is it? Please be re-assured though that it will settle down in a few days before you have to do it again!! Contact your Rheumy team of course if you're worried though, my GP was excellent and gave me a ECG but it was as suspected an uncomfortable side effect of the Rituximab and steroids. Hang on in there it will get better! X

  • Just wanted to add it was my second round, I didn't have it with the first round. X

  • Sorry to hear that and hope its just a blip. May I ask how you are doing in general on this drug? Its almost 2 months since my first cycle and still no sign of improvement. In fact I am having a bad flare now. I just hope its worth all this waiting. I wonder why you have suddenly experienced this reaction. Hope it is just temporary and you feel better quickly.

  • Hi Cathy I'm not sure how well I am doing really, my joints do feel better and I am in less pain but I get terrible fatigue and I had hoped this med would help that.

  • Thanks for your honesty Debs. Fatigue is also a big problem for me so I am sorry to hear that. They do say that rituximab is cumulative so you may gradually feel better hopefully.


  • Hi cathy

    Do you think you will be offered another round? I had first in april but doc didnt say anything to me about another. Does it all depend on how 1st goes or will the automatically do 2nd to get cumulative effect. I have had some improvement but would love more particularly with joint and muscle pain

  • Hi

    Its still all pretty new to me still but I finished my first round on 16 june and my follow up review is 31 august. I guess they will know from my bloods if I am responding and whether another round will be offered I don't know but likely I think. But I am still having bad flares so they may say it isn't going to work. I booked to see nurse next Wednesday to show him my current flare and ask his advice. You should have a review appointment lined up unless they are leaving you longer before assessing you. Chase them up as you need a follow up appointment date just for peace of mind. Where are you? I am in London. Its pot luck on the treatment/care you receive. I hope you continue to respond well.

  • Hi cathy

    Not back with rheumy till end of september. I have had a few flares since treatment however im generally better, though feeling achy today , i put down to change in the weather! Im in belfast, dispite the round about way i had to go to get diagnosed , i have a good rheumy now and the nurses are helpful. Its hard sometimes to get your head round it all but i try to keep positive as im sure my family get scundered with me at times but they are very good- ive 3 housetrained sons who can cook and help with cleaning!!!! Keep us updated with how you get on , i hope alls well and you get further biolgicals xx
