Coughing in the late stage of lung cancer is mainly due to tracheal and bronchial irritation caused by lung lesions, which results in coughing and coughing sputum. First of all, for patients with dry cough, they should mainly take cough suppressant medication, such as codeine phosphate three times a day, one tablet once. If patients have cough and sputum with difficult to cough, they can be treated with oral medication of Aphrodisiac tablets, one tablet once every eight hours, which can be increased to two tablets in severe cases. Secondly, in advanced stage of lung cancer, radiotherapy, chemotherapy and targeted drug treatment are mainly needed, which need to be combined with pathology and corresponding treatment plan to control the disease. After the lesions are shrunken, the corresponding cough symptoms can be improved.
