In adults with Mycoplasma pneumoniae infection, there may be characteristic manifestations of a dry cough without sputum that lasts for a long time. After the diagnosis of mycoplasma pneumoniae infection, the symptoms will gradually be relieved with the application of antibiotics, such as macrolides, fluoroquinolones or tetracyclines. The cough will still be recurrent for a long period of time before it is relieved, so medication can be applied to stop the cough symptomatically, but before stopping the cough, it is necessary to see if the patient has obvious coughing sputum. If the sputum can be coughed out or indeed there is no sputum, then cough suppressants can be chosen. The corresponding drugs can be selected from levopiperazine tablets, dioxopropazine hydrochloride tablets or pentoxifylline, dextromethorphan and so on, only one of which can be chosen. You can also choose proprietary Chinese medicines, such as the related lozenges and cough syrups. Chinese herbal treatment can also be prescribed according to the patient’s symptoms, and the commonly used formula can be chosen to stop coughing.
