If your baby has phlegm in the throat after the pneumonia has improved, you can give him or her Ambroxol oral solution to treat it. If the baby has phlegm in the throat within one year of age, it can also be treated by nebulized inhalation. The commonly used nebulized inhalation drugs are budesonide and terbutaline, which can dilate the airways and facilitate the discharge of phlegm. If you are recovering from pneumonia and have phlegm in your throat, it means that the inflammation has not been completely cured. For babies with severe cough and phlegm, you can also give your child anti-inflammatory drugs for treatment. In addition to the standardized use of medication, we must pay attention to the diet, reduce the intake of high-calorie and sweet food, so as not to produce more phlegm from sweet food, drink more water to keep the respiratory tract moist, and reasonable care can make phlegm discharge.
