Cough variant asthma is difficult to be completely cured, but it can be relieved by getting rid of allergens and applying medication to alleviate symptoms and reduce the number of attacks without affecting normal work and life. Cough variant asthma is a type of atypical asthma in which cough is the only symptom or the main symptom, and the patient does not have typical asthma signs and symptoms such as wheezing and shortness of breath, but there is airway hyperresponsiveness. The main manifestation of cough variant asthma is an irritating dry cough, which is usually severe and often accompanied by allergic rhinitis. Patients with cough variant asthma often have a personal or family history of allergies. If allergens or other irritants that cause cough variant asthma attacks can be identified, care should be taken to avoid exposure to these environmental factors. It should also be treated with glucocorticosteroids such as prednisone and budesonide, beta2 agonists such as salbutamol and formoterol, and theophyllines such as doxophylline and aminophylline under medical supervision. Patients with cough-variant asthma are advised to follow up regularly in the respiratory clinic, and if the treatment is not effective, adjust the treatment plan under the guidance of the doctor.
