Off-Label Uses for Intravenous Immunoglobulin Therapy

Intravenous immunoglobulin therapy boosts a patient’s immune response, making it a valuable treatment option when other methods fail.

Intravenous immunoglobulin (IVIG) therapy treats individuals with compromised immune systems caused by genetic disorders or acquired diseases. Immunoglobulins are blood antibodies that defend against infections.

IVIG preparations, derived from pooled plasma from over 1,000 healthy donors, are purified before administration. These preparations consist primarily of IgG, a naturally occurring immunoglobulin in humans, unaffected by immunization or antigen exposure.

Typically, IVIG infusions are administered every three or four weeks.

How does IVIG work?

IVIG therapy operates in two opposing ways:

  • Suppresses the immune system in patients with:
  • Autoimmune disorders
  • Solid organ or bone marrow transplants

What is IVIG used for?

FDA-approved uses for IVIG include treating the following immune-related disorders:

  • Primary humoral immunodeficiency
  • Multifocal motor neuropathy
  • B-cell chronic lymphocytic leukemia
  • Immune thrombocytopenic purpura
  • Kawasaki syndrome
  • Chronic inflammatory demyelinating polyneuropathy

What are the off-label uses for IVIG therapy?

In addition to FDA-approved conditions, IVIG is utilized in the treatment of various autoimmune and infectious diseases, as well as conditions with unknown causes.

According to the National Guideline Clearinghouse, off-label IVIG uses include:

  • Blood disorders:
  • Aplastic anemia
  • Pure red cell aplasia

  • Refractoriness to platelet transfusion
  • Neonatal alloimmune/autoimmune thrombocytopenia
  • Posttransfusion purpura
  • Thrombotic thrombocytopenia purpura
  • Hemolytic uremic syndrome
  • Infections:
  • Prevention of infection in conditions such as:
  • Low birth weight
  • Solid organ transplantation
  • Surgery
  • Trauma
  • Burns
  • HIV infection
  • Neurological disorders:
  • Epilepsy
