The presence of pharyngitis and cough with yellow sputum is usually due to inflammation of the pharynx caused by bacterial infection. At this time, if there is suppuration in the pharynx, the phenomenon of cough with yellow sputum may also occur. In addition, when the body’s resistance is weak, inflammation in the pharynx can migrate downward, causing inflammation in the bronchi and lungs. At this time, the bronchial tubes and lungs will secrete some inflammatory substances, and the phagocytes in the body will also gather at the inflammation site and devour foreign bacteria. At this time, the necrotic cells and inflammatory substances will mix together to form yellow sputum, so the symptom of cough with yellow sputum will appear. Antibiotics can be used for treatment, and the two drugs that are more commonly used clinically are cefradine and cefixime. If the cephalosporin has allergies, azithromycin, roxithromycin or erythromycin can be used for treatment as well. In addition, it is also necessary to take cough and phlegm medicine, for yellow phlegm effect is better lung power cough combination.
