Intravenous immunoglobulin (IVIG) is a therapy that involves administering a concentrated solution of immunoglobulins, which are proteins that act as antibodies, directly into a patient's bloodstream via a vein. IVIG is used to treat various immune system disorders, including immune deficiencies, autoimmune diseases, and certain neurological disorders. The solution is derived from human plasma and is composed of various antibodies to help supplement the patient's own immune system.
