Coughing is an important defensive reflex of the organism, a protective action that coughs secretions or foreign bodies out of the body.
Therefore, if coughing does not affect the normal life and learning of children, there is no need to use cough suppressants, especially in infants. Since the airways of small infants are relatively small and secretions tend to block the airways, if cough suppressants are used blindly, they may cause phlegm blockage and suffocation, which, on the contrary, is not conducive to the recovery of the disease.
However, if the cough is so severe that it seriously affects life, or if there are complications associated with a severe cough, such as subconjunctival hemorrhage or pneumothorax, you need to seek medical attention and choose the appropriate cough medicine to improve the symptoms under the guidance of a doctor.
