Market Overview

Immunoglobulin subcutaneous therapies involve the administration of human immunoglobulin G (IgG) via subcutaneous injection, enabling slower absorption and steady serum IgG levels. Compared to intravenous immunoglobulin (IVIG), SCIG offers reduced systemic adverse reactions and greater patient autonomy. These therapies are widely used for chronic immunodeficiency conditions requiring lifelong replacement therapy.

High-concentration formulations and infusion pump innovations allow flexible dosing schedules and reduced infusion frequency. The market is influenced by plasma availability, regulatory oversight, reimbursement frameworks, and patient education programs. Pharmaceutical companies focus on expanding product portfolios with improved tolerability, stability, and ease of administration.
