Allergic cough can be triggered by many allergens. For example, during pollen allergy seasons, one may react to pollen, and it is also possible to react to dust mites, dust, animal dander, paint, feed, and foods that may include allergens like seafood, eggs, and milk. Cold air can also trigger reactions in patients with allergic cough. When individuals with allergic cough come into contact with the aforementioned allergens, it may enhance the reactivity of their airways, causing persistent spasmodic contraction. As a result, patients may experience persistent, irritating dry coughs. In such cases, it is advised to promptly remove oneself from exposure to the allergens and take antihistamines orally, such as loratadine. It is also advisable to avoid contact with these allergens routinely to prevent the onset of allergic cough. (Please follow the doctor's prescription when using medications.)
