If a child coughs and wheezes, it is mainly caused by an allergic constitution. For example, they have acute bronchial asthma, or they belong to capillary bronchitis, or they belong to acute wheezing bronchitis. In this case, the early stage of coughing will soon lead to shortness of breath. In this case, the main thing to address is the allergic state. The airway reactivity is often very high when you have allergies. In this case, glucocorticosteroids can be given for nebulized inhalation treatment, and glucocorticosteroids can be used in the form of budesonide suspension for nebulization. This treatment can be given to children for 1-3 months or even longer to reduce the high airway reactivity so that the cough will not be shortness of breath.
