Intravenous Immunoglobulin (IVIG): is a blood product administered intravenously. It contains the pooled IgG (immunoglobulin (antibody) G) extracted from the plasma of over one thousand blood donors. IVIG’s effects last between 2 weeks and 3 months. It is mainly used as treatment in three major categories:
- Immune deficiencies such as X-linked agammaglobulinemia, hypogammaglobulinemia (primary immune deficiencies), and acquired compromised immunity conditions (secondary immune deficiencies) featuring low antibody levels.
- Inflammatory and autoimmune diseases.
- Acute infections.
