Human immunoglobulin-G

Adults: Neonates and infants: the dose of human immunoglobulin-G is 5 ml (250 mg)/kg body weight daily on 3 consecutive days. Further infusion may be needed, depending on how the baby progresses clinically. Children and adults: for combined therapy with antibiotics in severe bacterial or viral infections and A-/Hypogammaglobulinemia, the usual dose is 2500 to 5000 mg for adults and 50 to 150 mg/kg for children, given as a single dose. It is given by intravenous drip infusion or by direct intravenous infusion. If it is given as an intravenous injection, inject it very slowly. For Idiopathic Thrombocytopenic Purpura, the usual dose is 200 to 400 mg/kg daily for 5 consecutive days. If an adequate response does not occur, the additional doses are stopped. For Guillain-Barre Syndrome, the usual dose is 400 mg/kg daily for 5 consecutive days. For Kawasaki Syndrome, the usual dose is 400 mg/kg daily for 5 consecutive days (approximately), or 2000 mg daily by intravenous drip infusion.
