Intravenous Immunoglobulin (IVIG) is a plasma product used in the treatment of certain conditions related to the immune system.VIG therapy is done by administering medication directly into the bloodstream to help treat autoimmune diseases, immune deficiencies, and certain kinds of infections.
Antibodies are proteins the immune system produces to fight disease-carrying organisms. Research has shown IVIG can reduce fever and the risk of heart problems. The immunoglobulin used to treat Kawasaki disease is called gamma globulin. After your child is given IVIG, their symptoms should improve within 36 hours. If their fever doesn't improve after 36 hours, they may be given a second dose of IVIG.
