The fastest drip rate shall not exceed 3.0 ml/min (about 60 drops/min). Dosage: Follow the doctor's advice. Recommended dose: 1 Primary immunoglobulin deficiency or hypofunction, first dose: 400 mg/kg body weight; maintenance dose: 200-400 mg/kg body weight, the dosing interval depends on the patient's serum IgG level and condition, generally once a month. 2 Primary thrombocytopenic purpura: 400 mg/kg body weight per day for 5 consecutive days, maintenance dose 400 mg/kg body weight each time, the interval depends on the platelet count and condition, generally once a week. 3 Severe infection: 200-300 mg/kg body weight per day for 2-3 consecutive days. 4 Kawasaki disease: Use within 10 days of onset, the therapeutic dose for children is 2.0g/kg body weight, one time infusion.

Generally, there are no adverse reactions. Very few patients experience transient headaches, palpitations, nausea and other adverse reactions during infusion, which may be related to the rapid infusion speed or individual differences.
