Tracheitis due to postnasal drip is usually not treated with antibiotics. If there is a basis for bacterial infection, anti-infective treatment with penicillins and cephalosporins may be used. When bronchitis due to postnasal drip is not associated with a bacterial infection, the patient usually does not need to take antibiotics and the postnasal drip should be improved promptly. Antihistamines such as chlorpheniramine and decongestants such as pseudoephedrine may be used to relieve nasal symptoms. Nasal diseases, such as sinusitis, can be treated with negative pressure drainage, puncture drainage or surgery if medical treatment is not effective. When postnasal drip causes tracheitis with bacterial infection, patients should choose penicillin such as amoxicillin, cephalosporins such as cefixime and other antibiotics under the guidance of the doctor, which can help clear the infection and control the inflammation of the trachea. Bronchitis can also be caused by other diseases. If the symptoms continue to remain unrelieved, it is recommended to consult a doctor to clarify the cause of the disease and follow the doctor’s instructions.
