Yellow sputum and yellow nasal discharge from the respiratory tract is mainly caused by the infection of purulent bacteria due to the decrease of the body’s resistance. It should be possible to choose antibiotics that resist septic bacteria for treatment, such as choosing to use penicillin, amoxicillin clavulanic acid potassium, meloxicillin, ceftriaxone sodium, cefuroxime, cefoperazone, cefpiramide and erythromycin, azithromycin, clindamycin or levofloxacin. If necessary, yellow sputum and yellow nasal discharge can be taken for culture of pathogens, as well as antibiotic sensitivity test to select relatively highly sensitive antibiotics to fight bacterial infection in order to shorten the course of the disease.
