The Effects of Multiple Sclerosis

What is daclizumab, and how does it work?

  • Daclizumab (Zinbryta) is an injectable medication used for treating multiple sclerosis (MS). Its mechanism of action is not completely understood. Available data suggests that it may work by modifying immune processes that may be responsible for causing MS by interfering with the activation of lymphocytes (a type of white blood cell) that cause inflammation and destruction of nerves in patients with MS. Daclizumab does not cure MS. It decreases the number of MS flares and lesions.
  • The FDA approved daclizumab in May, 2016.
