Intravenous Immunoglobulin Market Size Worth USD 30.83 Billion by 2035, Growing at 7.49% CAGR – SNS Insider

The global intravenous immunoglobulin (IVIG) market is projected to grow from USD 14.98 billion in 2025 to USD 30.83 billion by 2035, at a CAGR of 7.49%. Growth is driven by expanding neurological indications, increased plasma collection capacity, and rising demand for immunoglobulin-based treatments. However, plasma supply dependency and a 100% U.S. tariff on imported IVIG products implemented in October 2025 pose significant constraints. North America leads the market, while Asia-Pacific shows the fastest growth.
