γγA 5-year-old child with allergic cough is recommended to be treated with oral montelukast sodium. Allergic cough, also known as cough variant asthma, refers to asthma with cough as the only or main symptom, the essence of which is inflammation of the airways. Leukotriene antagonists are anti-inflammatory drugs that can be used to treat inflammation of the airways and are more effective for cough variant asthma. 5-year-old children are often not able to cooperate with inhaled medication, and inhaled glucocorticoids are also more effective for treating cough variant asthma, but oral medication is a more appropriate means for children.γγIn addition to oral medication for allergic cough, children should also be careful to avoid exposure to allergens. If the child has allergic rhinitis also pay attention to observe the symptoms of allergic rhinitis. If oral montelukast sodium cannot control allergic rhinitis, glucocorticoid nasal spray can also be applied to treat allergic rhinitis.
