Allergic coughs can potentially be triggered by certain factors, such as exposure to allergens; common indoor allergens include dust mites and some fungi. Sometimes, contact with sensitizing substances can cause allergies, with common allergens including grain dust, pollen, flour, and animal fur. Additionally, some patients may experience allergic coughs triggered by exposure to certain medications, foods, and additives. Allergic coughs can also be caused by respiratory infections. Exposure to tobacco, air, and environmental pollution can also affect some patients, with common sources including cooking fumes from gas, smoke from cigarettes, and insecticide sprays. Therefore, patients with allergic coughs should avoid these risk factors and properly use inhaled corticosteroids to manage their condition.
