One of the key drivers for growth in the intravenous immunoglobulin market is the increasing incidence of immunodeficiency disorders, both primary and secondary.  For example, as per the NIH, over 6 million people are affected by primary immunodeficiency disorders globally. More than 430 different primary immunodeficiencies or primary immunodeficiency diseases (PIDs) have been described, caused by inherited defects in one or more components of the immune system. With advances in diagnostic technologies and enhanced awareness, an increasing number of patients are being diagnosed with conditions such as chronic inflammatory demyelinating polyneuropathy (CIDP) and multifocal motor neuropathy (MMN). These conditions necessitate the use of immunoglobulin treatment to avoid infections and control symptoms, substantially driving the steady demand for IV immunoglobulins.

Intravenous immunoglobulins (IVIg) are sterile preparations of concentrated antibodies derived from pooled human plasma and administered through intravenous infusion. They provide passive immunity by providing the body with ready-made antibodies that can be used to combat infections and help to regulate the immune response by neutralizing harmful pathogens. IVIg has been used extensively in the treatment of primary and secondary immunodeficiency, autoimmune, and inflammatory conditions, as well as certain neurological disorders.

Major players in the Intravenous immunoglobulin (IVIg) market include CSL Behring, Takeda Pharmaceutical Company, Grifols, Octapharma, and Kedrion. These companies dominate global supply through extensive plasma collection networks, large-scale fractionation facilities, and strong distribution capabilities. Their continuous investments in expanding plasma collection capacity, improving purification technologies, and securing regulatory approvals directly influence product availability and pricing, thereby shaping overall market growth.

The IV immunoglobulin market witnessed steady growth, growing from USD 10.8 billion in 2022 to USD 12.5 billion in 2025.
