Satralizumab is used to treat adults with neuromyelitis optica spectrum disorder (NMOSD). NMOSD is a rare, chronic autoimmune disease that causes inflammation in the central nervous system. This can lead to damage of the optic nerves, spinal cord, and/or brain. Satralizumab is used only if your body produces antibodies to a protein called aquaporin-4 (AQP4). Your doctor will test you for this antibody. Satralizumab may also be used for purposes not listed in this medication guide.
