Treatment for allergic cough includes the use of antihistamines, inhaled corticosteroids, and avoidance of allergens. It is caused by an overreaction of the immune system to certain substances. Symptoms of allergic cough mainly include a persistent dry cough, which worsens at night or in the early morning, often accompanied by a sore throat and chest tightness. It may be triggered by exposure to allergens such as pollen, dust mites, and pet dander.
1. The causes of allergic cough are related to abnormalities in the immune system. Genetic factors may make individuals more susceptible to allergies to certain substances; for example, people with a family history of asthma or allergic rhinitis have a higher risk. Environmental factors include air pollution, pollen, dust mites, and mold, which can irritate the respiratory tract and trigger allergic reactions. Physiological factors such as weakened immunity and impaired respiratory mucosal barrier function also increase the risk. Trauma or infection, such as an incompletely cured cold, may lead to increased respiratory sensitivity. Pathological factors such as chronic respiratory diseases may worsen allergic cough symptoms.
2. Medications for treating allergic cough include antihistamines such as loratadine and cetirizine, which can relieve allergic reactions; inhaled corticosteroids such as budesonide and fluticasone, which can reduce airway inflammation; and leukotriene receptor antagonists such as montelukast, which are suitable for asthma-related coughs. Avoiding allergens is key, such as regularly cleaning your home, using air purifiers, and avoiding contact with pet dander. Dietary adjustments can boost immunity, such as consuming more fruits and vegetables rich in vitamin C and avoiding spicy and irritating foods. For exercise, gentle aerobic exercises such as walking and yoga are recommended, as they help improve respiratory function.
3. Symptoms of allergic cough need to be differentiated from those of the common cold, asthma, and other illnesses. If a cough persists for more than 8 weeks and is accompanied by symptoms such as difficulty breathing or wheezing, you should seek medical attention promptly for lung function tests and allergen testing to obtain a definitive diagnosis. For patients with mild symptoms, self-management can be achieved by adjusting lifestyle and avoiding allergens. For patients with severe or recurrent symptoms, a long-term treatment plan should be developed under the guidance of a doctor, including medication and immunotherapy.
Treatment of allergic cough requires comprehensive management based on both the cause and symptoms. The main methods include medication, avoidance of allergens, dietary adjustments, and moderate exercise. If symptoms are severe or persistent, medical attention should be sought promptly to develop a personalized treatment plan.
