Rituximab : Uses, Dosage, Side effects, Brands & Price In India - 2026 Guide

What is Rituximab ?

Rituximab is a monoclonal antibody used to treat certain blood cancers and autoimmune diseases. It targets the CD20 protein found on many B lymphocytes, a type of white blood cell. Depending on the condition and treatment regimen, Rituximab may be used for non-Hodgkin lymphoma, chronic lymphocytic leukemia (CLL), rheumatoid arthritis and certain forms of vasculitis.

Rituximab is administered by intravenous infusion by trained healthcare professionals. The dose, infusion schedule and combination with other medicines depend on the condition being treated and the patient's medical history.

👉Why is Rituximab Prescribed ?

Rituximab is prescribed for specific cancers and immune-mediated conditions.

• Non-Hodgkin Lymphoma
• Chronic Lymphocytic Leukemia (CLL)
• Rheumatoid Arthritis
• Granulomatosis with Polyangiitis and Microscopic Polyangiitis
  

How Rituximab Works

Rituximab binds to the CD20 protein on B lymphocytes and helps the immune system eliminate these cells.

This can help control certain B-cell cancers and reduce abnormal immune activity in autoimmune diseases.

Rituximab may work through several mechanisms:-

• Activating immune-mediated destruction of B cells
• Triggering complement-dependent cell destruction
• Promoting antibody-dependent cellular cytotoxicity
• Reducing B cells that contribute to certain disease processes

Its effects depend on the disease being treated and the patient's response to therapy.

How to Take Rituximab

Rituximab is administered as an intravenous infusion by trained healthcare professionals in a suitable medical facility.

• The dose and schedule depend on the diagnosis and treatment regimen.
• The first infusion is generally started slowly.
• Infusion speed may be increased gradually if the patient tolerates treatment.
• Medicines may be given before the infusion to reduce infusion-related reactions.
• - Patients are monitored during and after administration.

⚠️ Important Instructions:

• Never self-administer Rituximab.
• Do not change the prescribed dose or infusion schedule.
• Inform the doctor about previous infusion reactions or serious allergies.
• Tell the treating team about any current infection or previous hepatitis B infection.
• Follow the recommended vaccination advice before starting treatment.

Rituximab can cause severe or potentially fatal infusion reactions. Hepatitis B reactivation and a rare serious brain infection called progressive multifocal leukoencephalopathy (PML) are also important risks.

Rituximab Dosage Variants

• Rituximab 100 mg/10 mL injection
• Rituximab 500 mg/50 mL injection

The actual dose is determined by the indication and treatment protocol. Some regimens calculate the dose using body surface area, while others use a fixed dose.

These vial strengths are not the same as a recommended patient dose. Only the treating specialist should determine the required number of vials and infusion schedule.
