Subcutaneous Immunoglobulin Market Size Worth USD 26.78 Billion by 2034 | CAGR: 9.11%

The subcutaneous immunoglobulin market size is expected to reach USD 26.78 billion by 2034, according to a new study by Polaris Market Research. The report “Subcutaneous Immunoglobulin Market Share, Size, Trends, Industry Analysis Report: By Product (IgG, IgA, and IgM), By Application, By End Use, and By Region; Market Forecast, 2025–2034” gives a detailed insight into current market dynamics and provides analysis on future market growth.

Subcutaneous immunoglobulin (SCIg) is a therapy administered under the skin to deliver antibodies that help maintain immune system stability in patients with immunodeficiency disorders. This market is witnessing expansion due to the growing shift toward home-based treatments, driven by the convenience and autonomy that SCIg offers patients. Unlike hospital-dependent infusions, SCIg enables individuals to manage their therapy in familiar settings, reducing the burden of frequent clinical visits. This flexibility improves treatment adherence and also enhances overall patient satisfaction and quality of life, reinforcing SCIg’s role as a preferred mode of immunoglobulin therapy.
