Patient Education

Rituximab Injection


Rituximab injection products are used alone or with other medications to treat various types of non-Hodgkin's lymphoma (NHL; a type of cancer that begins in a type of white blood cells that normally fights infection). Rituximab injection products are also used with other medications to treat chronic lymphocytic leukemia (CLL; a type of cancer of the white blood cells). Rituximab injection (Rituxan) is also used with methotrexate (Otrexup, Rasuvo, Xatmep, others) to treat the symptoms of rheumatoid arthritis (RA; a condition in which the body attacks its own joints, causing pain, swelling, and loss of function) in adults who have already been treated with a certain type of medication called a tumor necrosis factor (TNF) inhibitor. Rituximab injection (Rituxan, Ruxience) is also used in adults and children 2 years of age and older along with other medications to treat granulomatosis with polyangiitis (Wegener's Granulomatosis) and microscopic polyangiitis, which are conditions in which the body attacks its own veins and other blood vessels, which causes damage to organs, such as the heart and lungs. Rituximab injection (Rituxan) is used to treat pemphigus vulgaris (a condition that causes painful blisters on the skin and the lining the mouth, nose, throat and genitals). Rituximab injection products are in a class of medications called monoclonal antibodies. They treat the various types of NHL and CLL by killing cancer cells. Certain rituximab injection products also treat rheumatoid arthritis, granulomatosis with polyangiitis, microscopic polyangiitis, and pemphigus vulgaris by blocking the activity of the part of the immune system that may damage the joints, veins, and other blood vessels.
