If the cough does not heal for a long time and there is no specific medicine to treat it, go to the hospital for a comprehensive examination to find the cause of cough and carry out targeted treatment. If the cough lasts for a long time, the treatment time is relatively long. If the chronic infection of the respiratory system causes a prolonged cough, it is better to do sputum culture, select appropriate sensitive antibiotics for anti-inflammatory treatment according to the results of sputum culture, and use cough relieving and phlegm resolving drugs, such as Feilike Mixture or Niuhuang Snake Gall Chuanbei Solution. If cough variant asthma caused by airway hyperresponsiveness occurs, it will also lead to prolonged cough. Bronchial relaxation test or bronchial provocation test will generally be positive, so terbutaline sulfate and budesonide can be inhaled for treatment. If there is a lung tumor, surgery or chemotherapy or radiotherapy should be selected according to the specific situation of the patient.
