Zinbryta
Common Name:
daclizumab
How does this medication work? What will it do for me?
Daclizumab belongs to the class of medications called selective immunomodulators. It is used to treat adults with relapsing remitting multiple sclerosis (RRMS) who are experiencing an active episode of RRMS and for whom other treatments have not been effective or have caused intolerable side effects.
MS is a disease that affects the nervous system. It is believed that MS is an autoimmune disease (a condition in which an individual’s immune system starts reacting against their own tissues) and cannot be spread from person to person. For unknown reasons, the immune system sees the myelin sheath (a protective layer covering the nerves) as foreign and attacks it.
Daclizumab appears to affect the immune system by reducing its attack on the myelin sheath, slowing down damage to the nerves.
