IV immunoglobulin (IVIG) is a therapy used to treat patients with decreased or abolished antibody production capabilities. Antibodies are proteins your immune system produces to fight bacteria, viruses, and other foreign substances. If your body does not make enough antibodies, you are at a higher risk of developing infections.
In this case, you need to receive antibodies from an external source. Intravenous immune globulin therapy can supply your body with the necessary antibodies. Immune globulin is a sterilized solution made from the blood plasma of healthy donors. It contains a diverse collection of antibodies to fight different pathogens that might enter your body.
