Acute bronchitis is an acute inflammation of the bronchial mucosa, often accompanied by symptoms such as fever, cough, and productive cough. So, how should one treat acute bronchitis? Firstly, it's important to rest, stay warm, drink plenty of water, consume a light and easily digestible diet, and ensure that nutrition is adequate. Additionally, if the cause is a pathogenic infection, such as a bacterial infection, it is necessary to choose an effective antibiotic for treatment. Furthermore, symptomatic treatment is necessary; antitussive drugs can be used for a dry cough, expectorants for a productive cough, and antipyretic analgesics for fever. If there is bronchial spasm accompanied by chest tightness and asthma, asthma medications may be used.
