The main symptom of cough variant asthma is a dry cough, usually with fewer other “classic” asthma symptoms such as wheezing or shortness of breath. Cough variant asthma is one of the most common causes of chronic cough. The main symptom is a persistent dry cough, especially at night or in the early hours of the morning, which may be increased by colds, exposure to animal hair and pollen, and inhalation of cold air, and is usually accompanied by fewer of the other “classic” asthma symptoms, such as wheezing or shortness of breath. Dry cough caused by cough variant asthma is rarely treated with cough suppressants and antibiotics. Most patients can be treated with inhaled low-dose glucocorticosteroids combined with a long-acting adrenergic agonist such as salmeterol ticarcoson inhaler or a leukotriene modulator such as montelukast, or with a short-term oral dose of a small hormone such as prednisone, if necessary. Cough variant asthma need to go to the hospital in time, improve the examination, clear diagnosis, under the guidance of the doctor standardized treatment.
