How does Rebif work?

Rebif is an interferon therapy. Interferons belong to a family of proteins that naturally occur in the body. Rebif contains specifically interferon beta-1a. This type of interferon is identical to the body's natural human interferon beta. The exact way Rebif works is not known.

Although there is no cure for relapsing MS, Rebif has been proven to slow the progression of disability, which is the permanent worsening of your neurologic examination over time.
