When children have a cold with phlegm, the treatment includes:

1. Administering antiviral drugs or other appropriate medications based on the cause of the cold;

2. Providing specific oral cold medicines for treatment;

3. If there is a lot of phlegm, oral medications to reduce phlegm can be used in combination with other treatments. When there is less phlegm, parents can encourage the child to drink more water, frequently hydrate, and assist with patting the back, which helps to moisten and expel the phlegm.

For excessive phlegm, nebulization inhalation treatments can also be used, where the medication acts directly on the respiratory tract, helping with the absorption of respiratory tract phlegm. In severe cases, if there is a lot of phlegm with coughing discomfort or a severe cough, it is necessary to take the child to the hospital for detailed laboratory tests. Based on the specific pathogen causing the excessive phlegm and cold, targeted treatment should be given under the guidance of a doctor.
