Three FDA-Approved Drugs for Adults with Anti-Aquaporin-4 (AQP4) Antibody-Positive NMOSD

There are now three FDA-approved medications for maintenance in NMOSD. Anything else that is prescribed is done off-label.


In NMOSD, the likelihood of recurrent disease activity is greater than 90%. With the advent of the AQP4 antibody test, we recognize a wide variety of outcomes, but the condition can still have devastating long-term impacts. Ongoing treatment with medications that suppress the immune system and help prevent recurrence is generally necessary.

There are now THREE FDA-approved medications for maintenance in NMOSD. Anything else that is prescribed is done off-label.
