If you have a lot of sputum without coughing, you can take oral medications to help resolve the sputum, such as aminoglutethimide, eucalyptus pinene, acetylcysteine, etc., and pay attention to patting the back more often to help cough up the sputum. If the sputum is yellow and purulent, it mostly indicates a bacterial infection. It is recommended to go to the hospital to improve relevant examinations, such as blood routine, C-reactive protein, sputum smear or culture, chest X-ray or lung CT, etc., to clarify the presence of pneumonia and its specific pathogens. When a patient is diagnosed with bacterial infection, clinical treatment with antibiotics is required. Commonly used broad-spectrum antibiotics include cefixime, amoxicillin, cefaclor, cefuroxime, penicillin V potassium tablets, azithromycin, levofloxacin, etc. If the patient is also combined with infections of atypical pathogenic bacteria, azithromycin and erythromycin of macrolides, or levofloxacin and moxifloxacin of quinolones can be added. It is also recommended to eat more fruits, such as pears and bananas, which can moisten the lungs and relieve cough.
