Ocrevus (ocrelizumab) injection and Rebif (interferon beta-1a) injection are used to treat relapsing forms of multiple sclerosis (MS).

Ocrevus is also used to treat primary progressive forms of multiple sclerosis (MS).

Ocrevus and Rebif belong to different drug classes. Ocrevus is a CD20-directed cytolytic antibody and Rebif is made from human proteins.

Side effects of Ocrevus that are different from Rebif include upper and lower respiratory tract infections, infusion reactions (itching, rash, hives, redness, bronchospasm, swollen and sore throat, mouth pain, shortness of breath, flushing, hypotension, fever, fatigue, headache, dizziness, nausea, and fast heart rate), skin infections, depression, back pain, and pain in the extremities.

Side effects of Rebif that are different from Ocrevus include injection site reactions (pain, swelling, or redness) and flu-like symptoms (headache, dizziness, fatigue, fever, chills, stomach pain, runny or stuffy nose, and muscle aches).

Ocrevus may interact with other immune-modulating or immunosuppressive therapies, including immunosuppressant doses of corticosteroids.

Rebif may interact with alcohol, acetaminophen, aspirin, gout or arthritis medications (including gold injections), nonsteroidal anti-inflammatory drugs (NSAIDs), antibiotics, antifungal medicines, sulfa drugs, tuberculosis medicines, antiviral or HIV/AIDS medication, medicines to treat mental illness, seizure medications, birth control pills or hormone replacement therapy, anabolic steroids ("performance-enhancing drugs"), cancer medications, cholesterol-lowering medications, and heart or blood pressure medications.
