Rituximab injection is a monoclonal antibody treatment for certain cancers (like Non-Hodgkin Lymphoma, CLL) and autoimmune diseases (like Rheumatoid Arthritis, GPA, MPA, Pemphigus Vulgaris) that works by targeting and reducing specific immune cells (B-cells) that cause disease, administered intravenously under supervision due to potential infusion reactions and increased infection risk. 

What it is & How it Works

• Monoclonal Antibody: A lab-made protein designed to target the CD20 protein on B-cells (a type of white blood cell).

• Mechanism: It helps the immune system destroy these cancerous or overactive B-cells, slowing cancer growth or reducing inflammation in autoimmune conditions.
