What Is Intravenous Immunoglobulin Used For?

Intravenous immune globulin is used to strengthen the body's immune system, according to WebMD. It works by reducing the risk of infections in those with a weakened immune system.

Intravenous immune globulin is also used for increasing blood count in people with a certain blood disorder known as idiopathic thrombocytopenia purpura-ITP, by eliminating bleeding and forming blood clots, explains WebMD. Intravenous immune globulin is also occasionally used to treat multifocal motor neuropathy and Kawasaki syndrome.

Intravenous immune globulin is a sterile solution of concentrated antibodies taken from healthy donors. It is derived from a portion of the blood, known as plasma, where the immune globulins and other proteins are contained, according to BPI Pharma. For those being treated, regular infusions are required to maintain a healthy range of immune globulin levels in the body.
