Bronchitis and chronic coughing, if indicated by bacterial infection resulting in fever, coughing, and yellow phlegm, with elevated white blood cells and procalcitonin, should be treated with antimicrobial drugs based on the results of sputum culture and sensitivity testing. If the trachea is invaded by a virus causing coughing symptoms, symptomatic treatment should primarily be administered, and some proprietary Chinese medicines with antiviral properties, such as Banlangen granules or Lianhua Qingwen capsules, may be taken. If the bronchitis and coughing are caused by allergies, nebulized corticosteroids and antihistamines should be utilized for treatment. Regularly keep warm to avoid getting chilled, especially during the variable temperatures of early morning and evening in the winter and spring seasons. Timely adjustments in clothing are advisable along with strengthening physical exercise to improve the body’s resistance. (Note: Please follow medical advice regarding medications.)
