Hey.. I took Betaseron for two years, and then Ty for two years. Betaseron no longer helped my MS, so my doctor put me on Ty for two years, and it quit helping. The doctor is considering Rituxin. Has anyone else taken Ritixun? This disease is worsening, and I am getting discouraged. I was diagnosed five years ago, and I am forty-one. Yes, I will continue to fight, but all these drugs! :-) Any Rituxin encouragement out there?
