Cefprozil dry suspension belongs to the cephalosporin class of antibiotics, which can be taken orally in children with bacterial inflammation. The duration of oral administration is analyzed according to the child’s clinical symptoms, the level of white blood cell count, and the severity of the infection, but in principle, cephalosporin antibiotics should be used for about 1 week, and too long a period of time is prone to drug resistance, as well as a certain degree of damage to the child’s liver and kidney function. In severe cases, if oral administration is required for a longer period of time, further medication should be given under the guidance of the doctor, and other drugs should be replaced if necessary to avoid resistance to the same antibiotic. In mild cases, the drug is usually taken orally for about 3 days, and after clinical cure is achieved, the drug can be stopped orally, and other symptomatic applications can be given according to the child’s symptoms.
