If the cough is accompanied by nasal congestion, runny nose, sore throat, dry throat and hoarseness, it is likely to be caused by an upper respiratory tract infection and can be treated with cold medications such as Paediatrician’s Nurse Granules or Aminophen Pseudomal dispersible tablets. In addition, if there is pain in the throat, you can add Pudilan Anti-inflammatory Oral Liquid or Blue Scutellaria Oral Liquid for anti-inflammatory treatment. If the dry cough is severe, you can also use fenagan syrup to stop the cough. If the cough is heavy, deep and accompanied by coughing sputum, it is likely to be a case of bronchitis or pneumonia. First of all, a chest radiograph should be done to determine this, and if bronchitis or pneumonia does occur, the child should be hospitalized for infusion therapy. The medication for the infusion needs to be chosen according to the type of infection, such as intravenous antibiotics for bacterial infections or intravenous ribavirin for viral infections.
