The medication for dry cough in children caused by different pathogenic microorganisms is also different: 1. If the patient is caused by bacterial infection, antibiotics can be used for treatment, such as cefuroxime, cefaclor, amoxicillin. If the patient is allergic to cephalosporin or penicillin, oral azithromycin or erythromycin can be used. 2. If the patient has a viral infection, oral anti-inflammatory drugs are useless, and drugs to clear heat and detoxify the body, such as Qingkai Ling and Budilan, can be taken orally, or symptomatic treatment can be given, such as compound licorice tablets and pulmonary cough when the cough is heavy. 3. In the process of using these drugs, attention should be paid to the gastrointestinal reactions of macrolides.
