The choice of cough medication is related to the cause of the patient’s condition and individual differences, so there is no such thing as a good drug. Common causes of coughing include colds and pneumonia, which can be treated with drugs such as dextromethorphan and moxifloxacin. 1. Colds: are caused by viral infections and can manifest as fever, itchy throat, cough and other uncomfortable symptoms. Colds are self-healing diseases, and coughs caused by colds usually get better after the colds are cured. If the cough is obvious, you can use cough suppressants, such as dextromethorphan and cough syrup. 2. Pneumonia: mainly due to bacterial and other pathogenic infections, can be manifested as fever, cough, sputum and other discomforts, and the treatment of cough requires anti-infective treatment to alleviate the symptoms of coughing, and at the same time can be used to relieve the symptoms of cough suppressants. General bacterial infection can take moxifloxacin, cefuroxime and other anti-infective. In addition, gastroesophageal reflux disease (GERD), allergic rhinitis and many other causes can lead to coughing, and their treatment methods are different. Therefore, if you have a cough, you need to consult a doctor in time to identify the cause of the cough, and follow the doctor’s instructions to use medication, do not self-medicate.
