subcutaneous immunoglobulin
Also written as: SCIG — subcutaneous immunoglobulin
Immunoglobulin preparation administered via subcutaneous injection as an alternative to intravenous delivery.
Full Definition
A formulation of human immunoglobulin G specifically designed for subcutaneous administration, typically given weekly or biweekly. This route of administration offers advantages including home-based therapy, reduced systemic reactions, and more stable serum levels compared to monthly intravenous infusions. The subcutaneous route requires specific immunoglobulin preparations that have been modified to reduce local tissue reactions. It has become an important therapeutic option in pediatric immunology, particularly for patients requiring long-term immunoglobulin replacement therapy.
Usage
Usage note: May be abbreviated as SCIG or SubQ Ig in clinical documentation.
