Usage and Dosage:
Adults are usually injected intramuscularly or intravenously, 1~1.7mg/kg per body weight, once every 8 hours, and the course of treatment is 7~14 days. For patients with critical infection, the dose can be increased to 8 mg/kg per day, divided into several intravenous drips, but the dose should be reduced as soon as possible after the condition improves. The common dose for children is intramuscular injection or intravenous drip, according to body weight, 2 mg/kg for those born 0-7 days, once every 12 hours; 2 mg/kg for infants and children, once every 8 hours. For those with Ccr <70 ml/min, the maintenance dose should be adjusted according to the measured creatinine clearance. The injection of this product must be fully diluted before intravenous drip. The single dose can be added to 50-200 ml of 5% glucose injection or 0.9% sodium chloride injection to dilute it into a solution with a concentration of 1 mg/ml (0.1%), and infused within 30-60 minutes (the drip time must not be less than 20 minutes).
