If you have an itchy throat with phlegm and cough, we can treat the cause and the symptoms. First of all, we can take symptomatic treatment. If you have an itchy throat, you can take Fatty Sea tablets or Golden Voice tablets, and if you can’t cough up phlegm, we can use expectorants such as Ambroxol, eucalyptus pinene, acetylcysteine, bromhexine, etc. If the cough is heavy and affects rest and sleep, we can use cough medicines, such as compound licorice tablets, lung power cough strength, Su Huang cough capsule, strong loquat, etc. Secondly, we need to take treatment for the cause. The causative organisms that can cause the above symptoms include bacteria, viruses and atypical pathogens, and we need to use antibiotics for bacterial infections. For viral infections, we need to treat with antipyretic and antiviral drugs, while for atypical pathogenic bacteria, such as mycoplasma and chlamydia, we need to treat with macrolide antibiotics or quinolone antibiotics.
