Rituxan is a prescription medicine used to treat Non-Hodgkin’s Lymphoma (NHL), Chronic Lymphocytic Leukemia (CLL), Rheumatoid Arthritis (RA), Granulomatosis with Polyangiitis (GPA) and Microscopic Polyangiitis (MPA), and Pemphigus Vulgaris (PV). It is thought to work by targeting CD20-positive B-cells in the body that are involved in the disease process. Rituxan is administered as an intravenous infusion by a healthcare professional. The dose and schedule varies depending on your diagnosis. Your healthcare provider will determine what is appropriate based on your medical needs.
Serious side effects include infusion-related reactions that can lead to death, severe skin and mouth reactions (painful sores or ulcers on your skin, lips, or mouth), Hepatitis B virus (HBV) reactivation, progressive multifocal leukoencephalopathy (PML), tumor lysis syndrome (TLS), serious infections, heart problems, and kidney problems. Common side effects include infusion-related reactions, infections (which may include fever and chills), body aches, tiredness, nausea, low white and red blood cell counts, swelling, diarrhea, muscle spasms, and more frequent upper respiratory tract infections.
