Firstly, general treatment involves plenty of rest, drinking water, quitting smoking, avoiding strenuous activities, and so on. Secondly, medication is used, starting with symptomatic treatment. For example, for a cough with little or no phlegm, cough suppressants can be used; for thick sputum, expectorants are needed; antipyretic analgesics can be used for fever; and if there is bronchospasm accompanied by chest tightness and shortness of breath, asthma medication is necessary. Additionally, the use of antibiotics is dependent on evidence of bacterial infection, and common types such as macrolides, penicillins, and cephalosporins must be used under the guidance of a physician.
