Allergic cough, also known as cough variant asthma, and often accompanied by allergic rhinitis and allergic conjunctivitis, is often triggered by inhalation of cold air or irritating odors, indoor air pollution containing harmful gases, or exposure to allergens such as pollen, dust, and animal fur. For the treatment of allergic cough, anti-allergy treatment should be the main focus. Anti-allergy medications such as paracetamol, loratadine, cetirizine, sodium ejectate, ketotifen, etc. can be used to regulate desensitization. At the same time, cough suppressants can be used symptomatically. Three types of cough suppressants are commonly used, namely, central cough suppressants such as cough suppressant, which can directly inhibit the center in the brain and play the role of cough suppressant; terminal cough suppressants such as licorice combination, which produce cough suppressant effect by reducing the sensitivity of respiratory sensory nerve endings to stimulation; and inhalation glucocorticoids for anti-inflammatory treatment. Leukotriene receptor antagonists such as montelukast may also be used. In case of combined bacterial infection, antibiotic treatment is available, and in case of mycoplasma infection, erythromycin or azithromycin is required. For the treatment of allergic cough, the first step is to remove the patient from the allergen, followed by symptomatic anti-inflammatory treatment.
