Children with cough can take medications such as acetylcysteine granules. Children with cough consider infections:such as colds, pneumonia, bronchitis, etc., and also allergic reactions. If the cough is only mild, no medication can be used. Drink plenty of warm water, eat a light diet, avoid getting cold, and avoid stimulation of the respiratory tract by cold air and second-hand smoke. It can usually be cured on its own. If you have a severe cough with sputum and wheezing, it is recommended to go to the hospital for further examination to clarify whether it is mycoplasma infection or allergic cough. If mycoplasma infection is present, anti-infective treatment with azithromycin can be used, while allergic cough can be treated with nebulized inhalation of budesonide and terbutaline.
