Children can be given gammaglobulin, especially if they are suffering from a disease. If a child is suffering from immune thrombocytopenia or Kawasaki disease, gammaglobulin is used because it can effectively reduce immune damage in children, increase the level of platelet count and prevent coronary artery dilation caused by severe Kawasaki disease in children. However, the indications for the use of gammaglobulin in children must be well understood, and it should not be given to children casually, but under the guidance of a medical professional. Gammaglobulin is a blood product and has the risk of causing blood disorders, so parents must sign off on it before using it.
