Some patients still have a prolonged cough that lasts for 3~8 weeks after the symptoms of respiratory tract infection disappear in the acute phase, and there is no obvious abnormality in chest X-ray, among which the cough caused by viral cold is the most common, also known as "cough after cold".
If the cough is occasional, no medication is necessary.
If the cough symptoms are obvious, it is recommended to use antitussive drugs for a short time, among which compound methoxnamine has a certain effect in treating cough after cold.
If there is a lot of phlegm, oral expectorants can be taken, such as ambroxol, guaifenesin, etc.
Some children may have a prolonged cough due to increased airway reactivity after a respiratory infection, especially those with a history of wheezing, eczema, allergies, etc.
In addition to medication under the guidance of a doctor, you should also try to avoid contact with pollen, tobacco, pets, etc. The discharge of sputum can be promoted by nebulization therapy, back patting, expectorant medication or traditional Chinese medicine treatment. Increasing air humidity is also beneficial for improving respiratory comfort.
