For example, severe cough caused by cough variant asthma may require inhalation of glucocorticosteroids such as budesonide aerosol, or leukotriene receptor antagonists such as montelukast sodium; for example, patients with bacterial pneumonia may need to use drugs such as cefotaxime sodium or levofloxacin; lung cancer can also cause cough, which may require a combination of treatments, mainly surgery. 2. Cough symptomatic treatment: for example, some patients may need to use dextromethorphan hydrobromide, phenproperine and other therapeutic drugs to improve cough symptoms. To sum up, patients who can’t stop coughing need to consult doctor in time and take individualized treatment according to different causes.
