If you have a cough that does not stop, you should first observe whether the cough is a dry cough with or without phlegm. If it is a dry cough without phlegm, you can take cough suppressant medications for treatment, such as compound licorice combination or fenagan syrup. If it is a cough with phlegm, it is often due to an infection in the respiratory system and should not be treated with cough suppressants, but with phlegm-reducing drugs and anti-inflammatory drugs. If the sputum is white and thin, it is often a viral infection and can be treated with anti-inflammatory drugs such as Pudilan Anti-inflammatory Oral Liquid, Blue Scutellaria Oral Liquid or Ribavirin Granules. If the sputum is yellow and thick, it may be a bacterial infection, which requires antibiotics for anti-inflammatory treatment, such as cefradine, cefadroxil, cefadroxil or amoxicillin clavulanate potassium, all of which have good anti-inflammatory effects. The effect of phlegm-transforming drugs can be chosen from Ambrotero Oral Solution, Ambroxol Hydrochloride or Lung Power Cough Combination.
