What is Gamunex?
Intravenous immunoglobulin (IVIG) is a blood product administered intravenously. It contains the pooled, polyvalent, IgG antibodies 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 four major disease categories:
- Primary Immune deficiencies such as X-linked agammaglobulinemia (XLA), Common variable immunodeficiency (CVID) and hypogammaglobulinemia.
- Acquired compromised immunity conditions (secondary immune deficiencies) featuring low antibody levels.
- Autoimmune diseases, e.g. immune thrombocytopenia, inflammatory diseases, Kawasaki disease, and Guillain-Barre Syndrome.
- Acute infections.
There are numerous trade names of IVIG products, including Flebogamma, Gamunex, Privigen and Gammagard.
