Review Side Effects

Ocrevus® and Ocrevus Zunovo® are multiple sclerosis treatments that have been designed to reduce relapses in adult patients with relapsing MS (RMS) and to slow disability progression and reduce brain lesions in people with RMS and primary progressive MS (PPMS). They work by targeting and reducing specific B cells in the immune system that can cause inflammation and damage to the brain and spinal cord.

OCREVUS ZUNOVO is a ~10-minute subcutaneous injection given 2 times a year. Ocrevus Zunovo® is administered via a subcutaneous injection through a thin needle under the skin in the abdomen by a healthcare provider. If you take OCREVUS ZUNOVO, you will receive one (1) 920mg injection every 6 months, each lasting about 10 minutes. Before your first OCREVUS ZUNOVO injection, your healthcare provider or nurse will go over the injection process with you and answer any questions you may have. Your healthcare team will then monitor you closely in case you have an injection reaction.

Ocrevus® is a 2-4 hour infusion given 2 times a year. OCREVUS is an infusion therapy—also known as IV therapy—given as an intravenous infusion into a vein in your arm. If you take OCREVUS infusions, your first dose will be given as 2 separate 300 mg infusions 2 weeks apart, each lasting 2.5 hours. After your first dose, you will receive one (1) 600mg infusion every 6 months, each lasting 2 to 4 hours. Depending on what you and your doctor decide is right for you, you can receive your infusions at an infusion center, your doctor’s office, or at home.

Injection reactions are a common side effect of OCREVUS ZUNOVO, which can be serious and may require you to be hospitalized.

    • immune system

      The immune system uses many types of cells, including B cells and T cells, to help the body fight infections caused by viruses or bacteria.

    • B cells

      B cells produce antibodies and stimulate other proteins. In MS, these can cause damage to the central nervous system.

    • T cells

      T cells release chemicals that cause inflammation and damage. They also help to activate B cells.

    • lesions

      A brain lesion describes the damage MS causes to any part of the central nervous systems such as the brain or spinal cord.
