If the patient has cough symptoms, we should first improve relevant examinations to determine which disease causes the cough and which pathogen causes the cough. For example, if the patient coughs due to chronic bronchitis, we can take symptomatic treatment. We can take compound licorice tablet, Suhuang cough relieving capsule, dextromethorphan and other related drugs for treatment. If the patient's cough is caused by cough variant asthma, we need to take oral leukotriene modulator, montelukastner, inhale ics, such as sibycol or sulidade for treatment.
