  • Yes, Rebif does suppress the immune system.
  • Rebif contains a type of interferon called interferon beta-1a. Interferons are a group of proteins that are produced naturally by the body in response to viral infections.
  • Experts are not sure exactly how Rebif works for multiple sclerosis but believe it helps control immune system activities, preventing the immune system from attacking the myelin sheath.
  • Rebif helps to inhibit inflammation that can cause MS flare-ups, slow the progression of physical disability associated with MS, and reduce the number of relapses.
  • Rebif does not cure MS but it helps reduce the symptoms of MS and decrease the number of relapses.

Rebif is an interferon-beta (interferon beta-1a) that is indicated for the treatment of relapsing forms of multiple sclerosis in adults who are aged over 18. This includes clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease. It is not known if Rebif is safe and effective in children.

Rebif is administered by subcutaneous injection under the skin three times a week. It should be administered on the same three days and at the same time, if possible. For example, late afternoon on Monday, Wednesday, and Friday. Doses should be at least 48 hours apart.
