Chronic cough is a persistent cough lasting longer than eight weeks and can significantly impact daily life. Allergies are a common cause of chronic cough, triggered by allergens such as pollen, dust mites, pet dander, or mold. Here in California’s central valley, these symptoms can be heightened. When the immune system overreacts to these allergens, it can lead to inflammation and irritation in the airways, resulting in a chronic cough. Identifying and managing the underlying allergy is essential in effectively treating chronic cough.


Diagnosing the cause of chronic cough involves a comprehensive evaluation by a California allergist. This typically includes a thorough medical history review, physical examination, and possibly allergy testing. Allergy testing, such as skin prick tests or blood tests, can help identify specific allergens triggering the cough. Additional diagnostic tests, such as chest X-rays or pulmonary function tests, may be performed to rule out other potential causes of chronic cough, such as asthma, gastroesophageal reflux disease (GERD), or respiratory infection


Treatment for chronic cough associated with allergies focuses on managing the underlying allergy and alleviating cough symptoms. Avoiding exposure to allergens through lifestyle modifications, such as using air purifiers, keeping windows closed during high pollen seasons, and regularly cleaning dust-prone areas, can help reduce allergic triggers. Over-the-counter or prescription antihistamines and nasal corticosteroids may be recommended to control allergy symptoms and decrease inflammation in the airways, thereby reducing coughing. In some cases, allergen immunotherapy may be considered to desensitize the immune system to specific allergens and reduce allergic reactions leading to chronic cough. Additionally, addressing any underlying conditions contributing to the cough, such as GERD or asthma, is crucial for effective management.
