Sally,

Those who know me from various MS Forums know of my high doubts about the efficacy of Tysabri. After initially being excited about this new drug back in the summer of 2003, that feeling quickly disappeared as I followed Biogen's introduction of it and started to learn more and more about its dangers.

I too feel that its benefits don't outweigh the risks but at the same time respect anyone's decision to use it...IF they are told about ALL the pros AND cons about the drug. Tysabri is a monoclonal antibody that tampers with the immune system....and that can spell "trouble" in the long run.

I sure hope the many that choose to use it don't run into these possible problems. The Mayo Clinic didn't post this information for nothing!
