I have just finished first ever 4 week course of rituximab. I tried to look up the details before hand but the doc wasn't that clear in what I was getting. Which was lucky as it did not give me time to get worked up about side effects.
Every treatment we are given always carries a risk of side effects even the every day paracetamol. Everything we do has a risk of side effect. Some sound a whole lot more scarey than others.
The following week I had to sign a consent form and was warned about infection and not to get pregnant within the next year. Fine by me as no intentions of getting pregnant - ever

Am not a lesbian but pregnancy etc just never interested me so was able to turn it into a joke for the doc since he will meet many who may get upset by the news.
Once I had time to learn the possible risks I got over it by telling myself I cross the road most days of my life and what could be more dangerous than that? People even get killed on zebra crossings - designated crossing places etc. So the likelyhood of something negative happening as a direct result of rituximab is just as likely or unlikely as getting killed whilst crossing the road. I didn't go as far as looking up any statistics of fatalities of pedestrians crossing roads in designated spots but it did put life into perspective and able to 'get-on' with the treatment without any fuss.
I am one of the lucky ones who sailed through the four weeks. Admittedly next day I feel a little under the weather. The first week being the hardest for whatever reason. I sleep well each night after rituximab to say all I do is sit there. I received it on the day ward. First time it took 5 hours on slow so that body can adjust to it and to determine if its going to react. It didn't so all other weeks in been about 3 hours. The worst part is that carparking gets expensive. Highlight - freebie cup of tea. In otherwords for me it was quite a dull experience but that is positive and for now my platelets are up. They were up before the treatment started but if they hadn't a done so - as soon as steroids be alternate days my platelets may well have dropped again. I am now down to 2 steroids for 4 days then one steroid a day until I see him next in clinic on the 19th of this month
Today I kind of feel uncomfortably warmish or me (though have been doing all along this summer and may be the steroids) and under normal circumstances I be thinking that may be I am going down with a cold at vague times. But because I know just had the rituximab in a few days I be okay. Yeh, my blood pressure drops but I have low BP anyway and my temp was 37 last week where as all other weeks been 36. But very uneventful.
We need to read about the side effects but sometimes I wonder if we worry far too much or you get folk like me what admitts that every thing has side effects.... Admittedly am fearful of the brain infection one having had meningitus then septic shock later knowing how lucky I was with each and knowing that this there aint no cure. But life is life and we just have to seize the day because if we didn't do anything any time there was a fatality risk to it then we wouldn't get anywhere when I remember the crossing the road scenario because what has bigger risk than that in all honesty. Plus I do by chance happen to believe in God and he is my greatest reassurance at times about death and heaven and earth and life etc. I've been taught well and learned well and okay that don't mean to say I never fear. Because I do fear - but I have somewhere to place life and death fears and hope I haven't gone too deep for anyone but that is how it is for me and hope that it will provide some reassruance for others.
I have had IVIG in the past and that has caused more immediate problems for me than rituximab has done. I have had shivers and anemia issues (severe enough to be given full blood transfusion on the day I go home)with ivig and haven't had any thing like it with rituximab
