When children have symptoms of cold, cough and phlegm, treatment measures can be chosen according to the degree of illness, as follows: 1. If the symptoms of cold, cough and phlegm are not serious, medication is not recommended. You can encourage the child to drink more water, improve the indoor environment temperature and humidity, and keep the room ventilated. You should also encourage the child to eat more fresh fruits or drink fresh fruit juices to replenish vitamins and promote the recovery of the body. 2. If the symptoms of the child’s cold, cough, and sputum are relatively more serious, you need to alleviate the symptoms through medication under the guidance of a doctor. If it is a bacterial infection, you can take cefixime granules, combined with the application of cough, phlegm drugs, such as pediatric phlegm and cough granules for treatment. If it is caused by viral infection, it can be treated with Four Seasons Anti-Viral Oral Liquid or Ribavirin, which clears heat and removes toxins.
