Is it normal for someone just told they had ms to be put on tysabri (natalizumab) before other treatment?

Can Be: Depends on the individual's particular circumstances. Tysabri (natalizumab) can actually eliminate MS lesions in the central nervous system.

My opinion: Tysabri (natalizumab) has an FDA indication for first line use, and if a patient has quite active MS, I believe it is foolhardy to use less effective medications to start and then scale up after damage has become permanent. The first 5 yrs seem most critical in the quest to stabilize MS.
