Patients with phlegm in the throat can eat a light and liquid diet and try not to eat spicy and stimulating food. At the same time, they can eat watermelon, pear, grape, apple or sugar cane, which can effectively moisten the throat and reduce the symptoms of coughing and phlegm. In terms of medication, patients can take Golden Voice and Throat Pill, Sweet Orange and Bing Plum Tablets, Blue Scutellaria Oral Liquid, or Shuang Huang Lian Oral Liquid, which patients can selectively apply. After a week or so of active treatment, the patient’s condition should improve significantly. If no improvement is seen, the patient had better go to the hospital for detailed examination, and if necessary, the patient can add antibiotics orally, which are commonly used clinically as cefdinir dispersible tablets, or cefdinir capsules. Before using the drug, it is necessary to clarify whether the patient has a history of allergy to cephalosporin to avoid allergic reactions.
