Generic name: nusinersen (injection) (NUE si NER sen)
Brand name: Spinraza
Spinraza works by helping the body produce a protein essential to the function of nerves that control muscle movement. This protein is lacking in people with an inherited disorder called spinal muscular atrophy caused by a mutation in a specific gene.
Spinraza is used to treat spinal muscular atrophy in adults, children, and infants.
Spinraza may also be used for purposes not listed in this medication guide.

How is Spinraza given?
Your doctor will perform blood and urine tests to make sure you do not have conditions that would prevent you from safely receiving Spinraza.
Spinraza is injected directly into the fluid that surrounds the brain and spinal cord (cerebrospinal fluid). A healthcare provider will give you this injection.
The Spinraza takes about 1 to 3 minutes to complete. You may be given a sedative to help you relax and keep you comfortable during the injection.
Spinraza is usually given in a series of 4 "loading dose" injections, followed by "maintenance" injections.
The first 3 loading doses are usually given 2 weeks apart, followed by a 4th loading dose given 1 month later. Maintenance doses are then given once every 4 months.

What happens if I overdose?
Since Spinraza is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.
