There is no effective treatment for a runny nose and cough. The cause of the problem needs to be identified and treated in order to effectively relieve the symptoms. Runny nose and cough can be caused by colds or rhinitis, and you can choose general treatment and medication according to your situation. 1. Cold: Mostly caused by viral infections, it manifests itself as nasal congestion, runny nose, cough, phlegm and other symptoms. When the disease is mild, you should drink more warm water and pay attention to rest, which can help relieve the symptoms. When symptoms are obvious, nasal mucosal decongestants such as ephedrine drops can be used to reduce the symptoms of runny nose, dextromethorphan and other cough suppressants to stop coughing. In case of influenza, antiviral drugs such as oseltamivir should be used. 2. Rhinitis: mainly manifested as nasal congestion, runny nose, sneezing, itchy nose and other symptoms, such as excessive nasal secretion, can backflow to the throat and stimulate the throat to cause cough. For treatment, nasal mucosal decongestants such as ephedrine drops or anti-allergic drugs such as chlorpheniramine can be used to reduce symptoms. If there is a basis for bacterial infection, antibiotics such as erythromycin or ceftazidime may be used. Runny nose and cough can also be caused by other diseases. If the symptoms are not relieved or aggravated, it is recommended to consult a doctor in time, complete the examination, clarify the cause of the disease, and standardize the treatment under the guidance of the doctor.
