In adults with allergic cough, exposure to allergens leads to airway hyperresponsiveness, with coughing, sputum, wheezing, and a distinct croup in the lungs. For patients with severe wheezing symptoms, β2 agonists, such as salbutamol, or anticholinergic drugs, such as ipratropium bromide, can be inhaled as appropriate, and for severe symptoms, hormones can be administered intravenously until the wheezing symptoms are significantly relieved. It is also important to take rest during the coughing period, not to stay up late, to drink more warm water, and to avoid spicy and stimulating foods.
