Ocrevus (ocrelizumab) is a prescription drug that treats certain types of multiple sclerosis (MS) in adults by lowering B cell levels. Your response to this drug may vary based on your medical history and diagnosis.
Ocrevus is a type of immunosuppressant. It belongs to a class of medications called monoclonal antibodies.
What MS does
MS causes your immune system to attack the protective covering of your brain and spinal cord. This can cause inflammation and swelling in these areas, which interrupts the communication between your brain and body. MS can cause symptoms such as vision changes, muscle weakness, tingling, numbness, and difficulty walking.
What Ocrevus does
Ocrevus’s mechanism of action (how it works) is by lowering your level of B cells. These are a type of white blood cell that worsens MS in your body. Lowering the level of these blood cells weakens the activity of your immune system and helps relieve your MS symptoms.
If you have questions about how Ocrevus works, talk with your doctor or pharmacist.
Ocrevus comes as a liquid solution in single-dose vials. It’s given as an intravenous (IV) infusion (an injection into a vein given over time) by a healthcare professional.
Ocrevus begins working after your first infusion. However, each person receiving Ocrevus treatment will respond to the drug differently. Some people may see a reduction in their MS symptoms after only one dose. For others, it may take more time before they notice results.
Talk with your doctor or pharmacist if you have questions about how long it may take for Ocrevus to start managing your MS symptoms.
