Respiratory infections and coughs may require treatment of the cause as well as symptomatic treatment such as stopping the cough or resolving the phlegm. 1. Treatment of the cause: For example, bacterial respiratory infections are usually treated with antibiotics such as cefixime; Mycoplasma infections, for example, may need to be treated with drugs such as moxifloxacin. 2. Symptomatic treatment: for those who simply cough, cough suppressants can be used, such as phenproperine, dextromethorphan hydrobromide, etc. For those who cough with obvious phlegm, phlegm transforming drugs, such as eucalyptus-pinocampus enteric soft capsule or aminobromine hydrochloride, etc., are usually needed. Therefore, patients with respiratory infections and coughs need to seek medical attention and individualized treatment under the guidance of a doctor.
