Coughing at night is mainly caused by lying down at night, which causes secretions in the airways to return to the throat, and also by the relatively strong secretion of the body’s glands at night. The most common cases are bronchitis, pneumonia and asthma. For bronchitis with bacterial infection, antibiotics such as penicillin and amoxicillin should be administered early. And give some cough and phlegm relieving drugs, such as clearing lung and phlegm relieving cough granules, snake bile Chen Pi San, snake bile Chuan Bei Liquid, compound fenagan syrup, etc. For asthma, appropriate bronchodilator drugs, such as salbutamol, terbutaline, ipratropium bromide, etc., can be given orally or by nebulized inhalation to relieve symptoms.
