Generally, adult allergic cough is a manifestation of asthma and is difficult to cure on its own. Patients are advised to undergo active treatment in respiratory medicine. Adult allergic cough is a common respiratory disease that is highly prevalent in winter and spring. Allergens such as pollen, air pollution, noxious gases, animal hair, etc. can irritate the airways, leading to airway hyperreactivity, airway inflammation, causing symptoms such as dry cough, itchy throat, etc., itchy eyes, etc. Some patients may also develop itchy skin and wind clusters. The disease can generally lead to long-term recurrent and persistent coughing episodes of more than 3 weeks, which can be prolonged if the patient does not undergo treatment. Therefore, when allergic cough occurs, patients are advised to visit a hospital respiratory medicine department in a timely manner to find allergens and stay away from them in order to reduce coughing episodes, as well as anti-sensitization, anti-inflammatory and cough suppressant treatments in order to reduce the patient’s symptoms. In addition, patients are advised to stay away from the more common allergens such as pollen, dog hair, cat hair, peaches and seafood to prevent the development of allergic cough.
