What Is Rituximab?

Rituximab is a monoclonal antibody that targets CD20, a protein found on the surface of certain B lymphocytes. By binding to CD20, rituximab helps reduce these B cells and is therefore used in several conditions involving abnormal or overactive B cells.

Uses & Indications

Depending on the patient's condition and treatment protocol, rituximab may be used for:

Blood Cancers

• Non-Hodgkin's lymphoma
• Chronic lymphocytic leukemia (CLL)

Autoimmune & Inflammatory Conditions

Rituximab may also be used for certain autoimmune conditions, including:

• Rheumatoid arthritis
• Granulomatosis with polyangiitis (GPA)
• Microscopic polyangiitis (MPA)

The exact indication, dosage, and treatment schedule depend on the patient's diagnosis and the prescribing specialist.

How Zytux Works

Rituximab specifically binds to the CD20 antigen on B cells. This triggers mechanisms that destroy or remove these cells from the circulation. Reducing abnormal or overactive B cells can help control certain cancers and autoimmune diseases.

Administration

Zytux is administered as a slow intravenous infusion by a healthcare professional.

The dose and infusion schedule vary according to:

• Medical condition
• Body surface area or body weight where applicable
• Previous treatment
• Other medicines being administered
• Individual patient response

Do not self-inject or administer Zytux without appropriate medical supervision.

Premedication

Doctors commonly use premedication before rituximab infusion to reduce the risk or severity of infusion-related reactions. The treating physician determines the appropriate premedication regimen.

Important Safety Information

Rituximab can cause serious reactions, particularly during or after an infusion. Patients should be monitored by healthcare professionals during treatment.

Important risks can include:

• Infusion-related reactions
• Serious infections
• Hepatitis B virus reactivation
• Severe skin or mucosal reactions
• Reduced blood-cell counts
• Rare neurological complications such as progressive multifocal leukoencephalopathy (PML)

Tell your doctor about previous infections, current medicines, and any history of hepatitis B before treatment.

Common Side Effects

Possible side effects may include:

• Fever
• Chills
