Rituximab is a medication used to treat certain types of cancer and autoimmune diseases. It is a monoclonal antibody that works by targeting a specific protein on immune cells called CD20.
When used to treat cancer, such as non-Hodgkin's lymphoma or chronic lymphocytic leukemia, rituximab is typically given as an intravenous (IV) infusion. The dosage can vary depending on the specific condition being treated, the patient's weight, and other factors.
For autoimmune diseases like rheumatoid arthritis or certain types of vasculitis, rituximab may also be given as an IV infusion, often in combination with other medications.
The dosage and administration of rituximab should always be determined by a healthcare professional based on the individual patient's needs and medical condition. It's essential to follow your healthcare provider's instructions carefully when receiving rituximab or any other medication.
