Allergic cough, a collective term for cough due to a range of airway inflammatory conditions, may be caused by cough variant asthma, non-asthmatic eosinophilic bronchitis, allergic cough, allergic rhinitis, and post-infectious cough. It is not a direct result of infection and therefore anti-infective treatment is not effective. Treatment for allergic cough starts with identifying what causes the allergy and then moving away from the allergen. Anti-allergic treatment is also necessary, and cetirizine, loratadine, ketotifen, and paracetamol can be used to regulate desensitization. Patients with cough variant asthma can exhibit airway hyperresponsiveness and can be treated with anti-inflammatory therapy with inhaled glucocorticoids or a mixture of inhaled glucocorticoids + beta2 agonists, using such treatment for at least three months. At the same time, cough suppressants can be administered, either centrally, such as cough suppressant, or peripherally, such as licorice combination, to reduce the sensitivity of respiratory sensory nerve endings to stimuli by inhibiting the centers in the medulla oblongata. Patients with allergic cough should keep warm and avoid getting cold, open windows frequently to keep the indoor air fresh, and try to stay away from things that cause allergies.
