Rituxan is used to treat non-Hodgkin's lymphoma, chronic lymphocytic leukemia, rheumatoid arthritis, granulomatosis with polyangiitis, microscopic polyangiitis, and pemphigus vulgaris. Treatment indications are determined by a healthcare provider based on individual patient factors.
Rituxan is a monoclonal antibody that specifically binds to the CD20 antigen found on the surface of B cells. This binding triggers the destruction of these cells through immune mechanisms, reducing the number of abnormal or overactive B cells in the body.
Rituxan is administered as an intravenous infusion in a clinical setting by qualified healthcare professionals. Patients should be monitored for infusion reactions, infections, and other potential side effects. Pre-medication with corticosteroids, antihistamines, and acetaminophen is often given to reduce reaction risk. Treatment requires regular follow-up and blood monitoring.
