Allergen-induced asthma is a very common disease in clinical practice. The recovery time after exposure to allergens varies from person to person. Some patients, who are less sensitive to certain allergens, usually experience gradual improvement in symptoms after avoiding the allergen, which may take two to three hours. However, some allergens may cause more severe allergic asthma attacks, in which case medication is necessary to manage the symptoms. Commonly, appropriate use of anti-allergy medication and drugs to relieve bronchospasm are required for relief.

Therefore, the severity of allergic asthma symptoms caused by different allergens and the individual’s physical constitution varies. Thus, the recovery time after exposure to allergens varies from person to person.

How to test for allergens in allergic cough

For allergic cough, you can check for allergens by visiting a dermatology department for a blood test. Based on the results of the test, you can identify the allergens and isolate them to prevent allergic cough. In daily life, pay attention to a reasonable diet. Avoid overly greasy, spicy, or stimulating cold foods. It's beneficial to drink more warm water to boost metabolism, or you can boil some pear syrup, which helps relieve cough and dissolve phlegm.

How to test for allergens in allergic rhinitis?

Allergic rhinitis is very common in daily life, and its main trigger is the inhalation of allergens in the air by patients.

The most common method to identify allergens for allergic rhinitis is the use of an allergen test kit, through a skin prick test to determine the patient's allergens and the degree of allergy, etc. A series of targeted anti-allergy treatments can then be carried out to achieve a cure for allergic rhinitis.

Have you checked for allergens for allergic rhinitis?

Allergic rhinitis is a disease characterized by an allergic reaction to external substances. Since it involves allergies to external substances, it is necessary to identify what triggers the allergy, generally requiring an allergen test. Without testing the causes of allergies, the treatment is merely based on experience or a clinical diagnosis lacking in etiological understanding, which is insufficient from a pathological perspective. Moreover, after identifying the allergens, medication can be tailored according to the allergens, or general advice can be given to the patients, such as avoiding certain allergy-inducing substances. For instance, mangoes are commonly known to trigger allergies, and so are fish and seafood, thus specific guidance can be provided to avoid consuming certain foods.

What are the allergens for allergic cough?

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.)
