Intravenous Immunoglobulin Market Size & Share, By Revenue, 2025-2032

Expanding treatment applications are driving the demand for IVIG across global healthcare systems. IVIG is being increasingly adopted for managing conditions such as primary immunodeficiency (PID), chronic inflammatory demyelinating polyneuropathy (CIDP), immune thrombocytopenia (ITP), Guillain–Barré syndrome, and Kawasaki disease.

Growing clinical acceptance and efficacy evidence are supporting the use of IVIG in treating a wide range of autoimmune and neurological disorders. Physicians are also exploring emerging off-label uses where IVIG shows significant potential in managing difficult-to-treat inflammatory and immune-mediated conditions. The rising patient awareness and diagnosis rates are contributing to the greater utilization of immunoglobulin therapies in hospital and outpatient settings.

Market Driver

Rising Diagnosis and Healthcare Access

The rising rates of diagnosis and improved healthcare access are driving the adoption of IVIG therapies across global markets. Advancements in diagnostic technologies are enabling earlier and more accurate identification of immunodeficiency and autoimmune conditions.

Increase in clinician awareness is leading to more frequent and timely IVIG prescriptions, especially in neurology, hematology, and immunology specialties. Governments and health systems are increasingly including IVIG in essential drug lists and reimbursement programs.

In March 2025, the World Health Organization (WHO) reported that over 50 low- and middle-income countries have recently expanded their essential medicines lists to include IVIG therapies. This inclusion, coupled with growing national insurance schemes, has increased patient access to IVIG treatments for immunodeficiency and autoimmune disorders globally.

Market Challenge

Plasma Supply Constraints Increasing Supply-Chain Risk

A key challenge in the intravenous immunoglobulin market is reliance on human plasma, which is primarily collected from compensated donors. This dependence makes the supply chain vulnerable to disruptions caused by donor availability, regulatory restrictions, and collection bottlenecks. Limited plasma supply can lead to shortages, which impact treatment availability for patients with immune disorders.

Market players are expanding plasma collection networks, investing in donor recruitment programs, and enhancing collection efficiency through advanced technologies. Companies are also partnering with blood centers and increasing capacity at fractionation facilities to improve supply stability.

Market Trend

Next-gen Recombinant & Enhanced IVIG Products

A key trend in the intravenous immunoglobulin market is the development of next-generation IVIG products using advanced formulation technologies. Manufacturers are working on recombinant IVIG and nanoparticle-based variants to address supply limitations and improve therapeutic performance. These innovations are aiming to enhance product safety, reduce the risk of adverse reactions, and increase treatment consistency.

Efforts are directed toward low-viscosity and high-purity formulations that allow easier administration and better patient tolerance. Research and development pipelines are expanding to support broader clinical applications and improve manufacturing scalability.

In May 2024, Gliknik announced that its lead recombinant IVIG mimetic candidate, GL‑2045, received FDA Orphan Drug designation for the treatment of Chronic Inflammatory Demyelinating Polyneuropathy (CIDP). GL‑2045 is designed to mimic only the active Fc portion of IVIG, which allows lower dosing, improved safety by avoiding blood-borne pathogen risk, and enhanced manufacturing scalability.

Intravenous Immunoglobulin Market Regional Analysis

Based on region, the market has been classified into North America, Europe, Asia Pacific, Middle East & Africa, and South America.

Intravenous Immunoglobulin Market Size & Share, By Region, 2025-2032

North America intravenous immunoglobulin market share stood at around 41.20% in 2024, with a valuation of USD 6.54 billion. This dominance is largely driven by the region's well-established plasma collection infrastructure, especially in the U.S., where public and private entities operate a widespread network of donation centers. These facilities adhere to stringent regulatory standards and play a major role in global plasma supply.

The consistent and large-scale availability of raw plasma enables manufacturers to maintain stable production and effectively meet rising clinical demand with minimal supply chain disruptions.

In October 2024, CSL Plasma introduced the Rika Plasma Donation System at seven Houston-area centers. The Rika system, developed by Terumo Blood and Cell Technologies, accelerates plasma collection to an average of 35 minutes, which is about 15 minutes faster than standard machines, while limiting extracorporeal blood to no more than 200 mL for donor safety.

The intravenous immunoglobulin industry in Asia Pacific is set for a significant CAGR of 7.70% over the forecast period, owing to increasing autoimmune diseases, such as myasthenia gravis and Guillain–Barré syndrome, and neurological disorders that respond well to IVIG treatment.

In March 2024, the National Library of Medicine reported that the Guillain–Barré syndrome in Asia Pacific is rising, with Taiwan recording 1.71 cases per 100,000 person-years and cases in South Korea increasing from 1.28 to 1.82. In East Asia, the rates range from 0.44 to 0.67, with prevalence rising to 20% every decade.

Factors such as lifestyle changes, aging populations, and improved diagnostics are leading to more frequent identification of these conditions. As awareness among physicians grows, IVIG is becoming a more commonly prescribed treatment, boosting market demand.

Regulatory Frameworks

In the U.S., IVIG is regulated by the Food and Drug Administration (FDA) under the Public Health Service Act and Title 21 of the Code of Federal Regulations (Parts 600–680). Manufacturers must submit a Biologics License Application (BLA) with clinical, manufacturing, and safety data. Plasma collection centers must be separately licensed. Current Good Manufacturing Practices (CGMP), post-marketing surveillance, and mandatory adverse event reporting ensure continued safety and product consistency.
In the European Union (EU), IVIG is classified as a biological medicinal product and is regulated under Directive 2001/83/EC and Regulation (EC) No 726/2004. The European Medicines Agency handles centralized marketing authorizations, while national agencies manage batch release and pharmacovigilance. Manufacturers must comply with EU Good Manufacturing Practices, submit Periodic Safety Update Reports, and implement comprehensive risk management plans. EudraVigilance is used for adverse event monitoring across the member states.
Japan regulates IVIG under the Pharmaceutical and Medical Devices Act. The Pharmaceuticals and Medical Devices Agency reviews clinical, non-clinical, and manufacturing data in line with International Council for Harmonisation (ICH) guidelines. Plasma collection and fractionation facilities must be licensed. Post-marketing obligations include adverse event monitoring, safety re-evaluations, and quality audits. The Ministry of Health, Labour and Welfare handles the reimbursement and policy-level oversight following product approval.
China’s National Medical Products Administration governs IVIG through its biological product regulatory framework. Approval requires a full clinical, non-clinical, and CMC (Chemistry, Manufacturing, and Controls) data submission. Manufacturers must meet China GMP standards and participate in post-market surveillance. While there is no formal interchangeability pathway, domestic regulations increasingly reflect international norms, especially in adverse event monitoring, virus inactivation processes, and batch consistency reviews.
