A cough that occurs every night needs to be treated by considering respiratory diseases of choice. The main etiology is commonly an inflammatory response, such as bronchitis, pneumonia, and lung abscess. Bronchial asthma and cough variant asthma are also common nocturnal coughs. You should get a good night’s sleep and not stay up late. You can choose cough suppressants such as finasteride cough syrup, cotrimoxazole capsules, cotrimoxazole oral solution, cotrimoxazole syrup, cotrimoxazole dextromethorphan oral solution, etc. For the cause of cough with bacterial infection, sensitive antibiotics such as penicillin, amoxicillin, cefuroxime, clindamycin, and levofloxacin should be used early. In addition, if the cough is relatively severe and affects sleep, bronchial asthma and cough variant asthma caused by cough can be appropriately treated with cough suppressants with hypnotic effect, such as loratadine, cetirizine and other drugs.
