When there is phlegm in the throat and coughing occurs, it proves that the inflammation is limited to the upper respiratory tract and does not extend to the lungs, so it is still relatively easy to treat. First of all, you can take throat-clearing drugs, such as Luo Han Guo granules or Pu Di Lan anti-inflammatory oral liquid, sweet orange and Bing Mei tablets, and Golden Voice Throat, all of which have certain anti-inflammatory effects. If the effect is not good after taking the medicine, it is recommended to check the blood routine to see if there is any elevated white blood cells. If there is an elevated white blood cell, it indicates a combination of bacterial infection, and it is necessary to take antibiotics for treatment at this time. For upper respiratory tract infections, the more effective antibiotics are cefixime or amoxicillin clavulanate potassium. However, these two drugs need to be changed to azithromycin for administration if there is an allergy.
