Intravenous Immune Globulin (IVIG).

o Intravenous immune globulin ("IVIG") is a product made up of human antibodies that can be given intravenously (through a vein). Antibodies are proteins your body makes to help you fight certain infections.

Antibodies, or immunoglobulins, are proteins naturally made by our body�s immune systems to fight infections.

However, sometimes the body is unable to make those antibodies due to any autoimmune disease present in the patient�s body. In other instances, the antibodies are being made, but because of a disorder, they do not function correctly.

In these cases, antibodies (also known as immunoglobulins) have to be given externally in the form of a medicinal product or drug.

Intravenous immune globulin (IVIG) is a product made up of antibodies (taken from human blood/pooled plasma of blood donors) and is given intravenously or subcutaneously to the patient. For some brands, IVIG therapy can be given to children starting from two years of age.
