The main manifestation of bronchitis patients is cough. The treatment of cough in bronchitis patients is as follows: 1. If the cough is mild, patients can drink more warm water, or they can take Chinese medicines, such as compound licorice combination, loquat paste, loquat extract and other cough expectorants; 2. If the cough is more severe, patients can take over-the-counter medicines, such as dextromethorphan; 3. If the condition continues to deteriorate and the treatment is not effective, patients need to consult a doctor and use the medicine according to the doctor’s instruction, so as to avoid delaying the diagnosis and treatment and causing unnecessary consequences.
