Cough and sputum are common symptoms of respiratory diseases, and many diseases can cause cough and sputum. For cough followed by phlegm in the throat, anti-inflammatory treatment can usually be given, such as taking anti-inflammatory drugs like cefdinir, amoxicillin, and levofloxacin. Symptomatic treatment can also be given with drugs to stop coughing and reduce phlegm, such as honey-refined Chuanbei loquat paste, lung power cough combination, and amiloride hydrochloride dispersible tablets. If the anti-inflammatory, cough suppressant and phlegm-relieving effects are not effective, patients need to go to the hospital for chest X-ray or chest CT examination to clarify whether there are other diseases in the lungs, such as pulmonary tuberculosis, lung tumor, pneumoconiosis, etc. Usually, the patient should pay attention to a lighter diet and eat less spicy and stimulating food.
