Neuromyelitis optica doesn’t have a cure or FDA-approved medications to treat it. Your doctor may give you a corticosteroid shot to help with swelling. He may also try a treatment that takes out some of the liquid part of your blood, called plasma, and replaces it with a man-made version. It’s called plasma exchange (PLEX).
Immunosuppressant medications such as azathioprine, methotrexate, mycophenolate and rituximab can be used to prevent further attacks.
