Cough and white sputum often indicate inflammation of the respiratory tract, such as upper respiratory tract infection, pharyngitis, bronchitis, pneumonia, tuberculosis and other diseases, which can cause cough and white sputum, and can be treated with anti-inflammatory, cough-suppressing and sputum-reducing drugs, such as cefdinir or amoxicillin anti-inflammatory, and cough-suppressing and sputum-reducing treatments such as honey-refined Chuanbei loquat cream or amoxicillin dispersible tablets. If the above treatment is not effective, or if the patient has a long history, it is necessary to go to the hospital to take a chest X-ray, or to do chest CT and other tests to further clarify the diagnosis. If the inflammation is severe, treatment can be changed to intravenous antibiotics. If tuberculosis is present, anti-tuberculosis medication will be required. If there are other causes, treatment will also be needed to address the cause.
