What is Ocrevus?
Ocrevus (ocrelizumab) is a monoclonal antibody that affects the actions of the body's immune system. Monoclonal antibodies are made to target and destroy only certain cells in the body. This may help to protect healthy cells from damage.
Ocrevus is used to treat primary progressive multiple sclerosis and relapsing forms of multiple sclerosis in adults (including clinically isolated syndrome, relapsing-remitting disease, and active secondary progressive disease).
Ocrevus may also be used for purposes not listed in this medication guide.
Ocrevus may cause unpleasant side effects. Some side effects may occur during the injection or up to 24 hours later. Tell your caregiver if you feel dizzy, nauseated, itchy, or have chest tightness, trouble breathing, or swelling in your throat.
Ocrevus affects your immune system. You may get infections more easily, even serious or fatal infections. Call your doctor if you have a fever, chills, cough, mouth sores, skin sores or blisters, itching, tingling, burning pain, or problems with speech, thought, vision, or muscle movement.
If you've ever had hepatitis B, it may become active or get worse while you are using or after you stop using ocrelizumab. You may need frequent liver function tests for several months.
Before taking this medicine

active infection with hepatitis B.
Your doctor may perform tests to make sure you do not have hepatitis B or other infections.
You should not receive any "live" or "live-attenuated" vaccine, within the 4 weeks before you start treatment with Ocrevus. If you need a "non-live" vaccine, you should receive it at least 2 weeks before you start treatment with ocrelizumab.

Ocrevus is not chemotherapy, it is a type of targeted treatment that works by binding to a protein called CD20 that is present on the surface of B-lymphocytes. Ocrevus may be used to reduce inflammation, reduce the risk of relapse, and delay the rate of disease progression in people with multiple sclerosis.
Ocrevus starts to work within about 12 weeks; however, it may take a few years for the full effects to be seen. Continue reading

Ocrevus works in MS by targeting a specific protein, called CD20 that exists on the surface of immature and mature B-lymphocytes. B lymphocytes are a type of white blood cell which are thought to contribute to the development of MS in several different ways, including secreting antibodies during an MS attack that cause inflammation which damages the myelin coating around nerve cells in the brain and spinal cord. When Ocrevus binds to CD20, it causes B-cells to self-destruct or disintegrate, which reduces the number of MS relapse and the rate of disability progression. Continue reading
An Ocrevus infusion takes at least 2.5 to 3.5 hours, depending on how long you have been having the infusion for and if you develop any infusion reactions during the process. However, the whole infusion appointment will take around 5 to 6 hours, because there is a pre-infusion check-up, during which you will receive medications that reduce infusion reactions, and you will need to wait for at least an hour post-infusion so your healthcare team can monitor you for any side effects or infusion reactions.
