As expected I was extremely tired after. It’s because of the large amount of Benadryl that is given. I was in bed asleep by 9:00. I’d love to say that was unusual for me, but during the week that’s my normal bed time. I woke up with a little stomach ache. That can be a number of reasons but it is listed as a side effect of the rituxan. I don’t remember it from any of the other times I took the medicine.
I know I’ll feel sluggish most of today and bloated. On top of the steroids they also pumped in two huge bags of liquids with the rituxan medicine. If I decided to step on the scale today, I wouldn’t be shocked to see a 5lb or more weight gain. That is just from the infusion. Its scary what these medicines really can do in the course of 24 hours to your body. It will come off in a few days but until it does, that bloat feeling is very uncomfortable.

As you go further up the ladder in MS drug therapies, the drugs side effects are more dangerous and more complications can occur. It is important to really understand the risk versus benefits when you get to these drugs for MS. Right now these are your some of the infusion therapies; Rituxan or Ocrelizumab, Lemtrada, Novantrone and Tysabri. Just remember knowledge is power. Research and question if your looking into any of these drugs for multiple sclerosis.
I was on Tysabri for 18 months and never had any adverse side effects. This is my 3rd infusion with Rituxan and except for minor side effects, I’ve been fine. Like MS, drug reactions are different in everyone. I can only tell you from my own experiences.
