Your Guide to Ocrevus and Ocrevus Zunovo for Multiple Sclerosis (MS)

Ocrevus may also be used for other conditions as determined by your healthcare provider.

How does Ocrevus work (mechanism of action)?

Ocrevus attaches to a protein called CD20 on certain immune cells known as B-cells. Normally, B-cells help protect your body from infections, but in people with multiple sclerosis, they mistakenly attack your nerves. By attaching to CD20, Ocrevus helps destroy the B-cells that are causing this nerve damage.
