Ocrevus (Ocrelizumab): A Breakthrough Treatment for Multiple Sclerosis

Multiple sclerosis (MS) is a chronic central nervous system disorder that affects millions of people worldwide. It is characterized by the immune system mistakenly attacking the protective covering of nerve fibers, leading to communication problems between the brain and the rest of the body. Over the years, advancements have been made in the treatment of MS, and one such breakthrough medication is Ocrevus (Ocrelizumab).

Understanding Ocrevus

Ocrevus is a monoclonal antibody that targets a specific protein called CD20, which is present on the surface of immature and mature B-lymphocytes, a type of white blood cell. These B cells are believed to play a role in the development of MS by secreting antibodies that cause inflammation and damage the myelin coating around nerve cells in the brain and spinal cord. By binding to CD20, Ocrevus prompts the self-destruction of B cells, effectively reducing their harmful effects².

Treating Multiple Forms of MS

Ocrevus is approved for the treatment of two forms of MS: relapsing remitting MS (RRMS) and primary progressive MS (PPMS). RRMS is characterized by periods of relapses, or flare-ups, followed by periods of remission, while PPMS is characterized by a gradual worsening of symptoms over time. Ocrevus has shown efficacy in reducing the number of relapses in RRMS patients by approximately two-thirds (70%)².

The Administration Process

Ocrevus is administered as an intravenous infusion every six months, following an initial dose of two infusions given two weeks apart. The infusion is typically conducted in a clinical setting under the supervision of healthcare professionals. During the infusion, patients are closely monitored for any signs of infusion reactions, which are a potential side effect of Ocrevus.

Managing Side Effects

While Ocrevus has demonstrated significant benefits in treating MS, it is essential to be aware of its potential side effects. Infusion reactions are a common side effect of this medication and can range from mild to severe. These reactions may include symptoms such as fever, chills, fatigue, rash, and shortness of breath. In some cases, infusion reactions may be serious and require hospitalization. To ensure patient safety, monitoring is conducted during the infusion and for at least one hour afterward².

Additionally, Ocrevus can increase the risk of infections, particularly upper and lower respiratory tract infections, skin infections, and herpes infections. It is crucial for patients to promptly report any signs of infection to their healthcare provider to receive appropriate treatment².

Is Ocrevus Right for You?

Deciding on the most suitable treatment approach for MS should be done in consultation with a healthcare professional. They will consider various factors, including the individual’s medical history, disease progression, and specific treatment goals. Ocrevus has shown promise in the treatment of MS, particularly for those with RRMS or PPMS, but it may not be suitable for everyone.


Ocrevus (Ocrelizumab) represents a significant advancement in the treatment of multiple sclerosis. By targeting B cells and reducing their destructive effects on the nervous system, Ocrevus offers hope to patients living with MS. However, it is essential to have a thorough discussion with a healthcare provider to assess the benefits and risks of Ocrevus and determine its suitability for each individual case.
