Rituxan in the “MS world” is used to slow down the progression of the disease by lengthening the time between attacks. It kills the B-cells, which are the cells that tell the T-cells to attack the Myelin. The Myelin is what covers and protects our nerves, spinal cords and brain. I have experienced a reduction of numbness and increase in energy. And what has been so amazing have been my MRI results, which have been stable for the past 6 months! YAY!
