TYSABRI® (natalizumab) is a prescription medicine used to treat adults with relapsing forms of Multiple Sclerosis (MS). TYSABRI can slow the worsening of symptoms common in people with MS and can decrease the number of flare-ups (relapses). TYSABRI increases the risk of PML. When starting and continuing treatment with TYSABRI, it is important that you discuss with your doctor whether the expected benefit of TYSABRI is enough to outweigh this risk.
