Bronchitis that is triggered by common allergens, instead of respiratory conditions such as cold and flu, is called allergic bronchitis. Sufferers experience the same bronchial reaction symptoms caused by acute bronchitis, and a cough is the initial manifesting symptom. Proper identification of an allergic reaction as the bronchitis trigger is required for diagnosis and treatment.

Significance
-
Allergic bronchitis is caused by an inflammation of the bronchial tubes that can lead to irritation of the lining of the lungs. Coughing occurs as a reflex to clear the lungs, in response to the mucus production brought about by an irritated bronchial lining.
Identification
-
Bronchitis triggered by allergens causes irritation to the bronchi and the lower airways of the respiratory system. The illness may be accompanied by asthma, which is sometimes referred to as allergic asthma.
Features
-
Symptoms like coughing are triggered by inhaling substances such as pollen, mold, dust, smoke and other allergens. These are irritants that affect the lower respiratory system, such as the trachea and bronchial lining, causing them to become inflamed, release mucus, and stimulate the cough reflex.
Symptoms
-
Early symptoms of bronchial reaction include stuffy nose, an itchy throat, mucus build-up and sore throat. Difficulty in breathing may occur as the bronchitis progresses. Cough is an initial response to the irritation of the bronchi. Mucus production results from inflammation of the bronchial lining. Sputum may be white, yellowish-gray or green in color. Shortness of breath may occur with even mild exertion. In some cases, the patient becomes fatigued, with restlessness, wheezing, fever, chills and chest pain.
Causes
-
Allergens are the main cause of allergic bronchitis, as opposed to the viruses and bacteria that cause non-allergic bronchitis. The allergens trigger an abnormal immune response that results in the manifestation of bronchial symptoms. The condition may persist with continued exposure to allergens. Allergens include animal dander, pollen, mold spores, fabrics, dust mites, secondhand smoke and toxins.
Considerations
-
Cough accompanied by fever requires immediate medical attention when someone is suffering from a bronchial infection. A cough lasting for more than three weeks may result in asthma and other serious respiratory complications.
Management
-
Because exposure to allergens triggers bronchitis symptoms, avoiding them can reduce irritation to the respiratory system. Steroid therapy may be indicated to manage bronchial inflammation. Acetaminophen or ibuprofen can help reduce any fever. The person must be hydrated to aid in the expulsion of mucus from the bronchial tubes.
