After suffering from bronchitis, coughing is one of the most common symptoms. How should a cough due to bronchitis be treated? First, the treatment should target the cause of the bronchitis. For instance, if it is caused by a bacterial infection, a sensitive antibiotic should be chosen. If it is caused by a mycoplasma infection, an antibiotic effective against mycoplasma should be used. Additionally, medication should be used to specifically address the cough. If it is a dry cough, antitussive and cough suppressant medicines can be used. However, if it is a cough with a lot of phlegm, expectorants should be chosen, and cough suppressants should be used cautiously, especially in cases where the phlegm is thick and difficult to expel, or in elderly or frail individuals. (Please use medication under the guidance of a doctor.)
