For the treatment of whooping cough, the first step should be to drink plenty of water and maintain a suitable indoor temperature and humidity. In terms of medication, it is necessary to choose macrolide antibiotics and adhere to an inflammatory treatment course. Clinically common drugs include erythromycin, roxithromycin, azithromycin, clarithromycin, etc., and generally, medication is required for at least about ten days. At the same time, it is recommended to use antitussive and expectorant drugs. If there are symptoms of breathing difficulty, oxygen inhalation can also be administered. There are many expectorant drugs clinically available, such as carbocisteine or She Dan Chuan Bei liquid, ambroxol oral solution, etc., all of which can serve the function of suppressing coughs and expelling phlegm.
