What Is Allergy?
An allergy occurs when your body’s immune system sees a substance,
called an allergen, as harmful and overreacts to it.
2 This is an allergic reaction which causes the symptoms
that you experience. 2 Allergens can get into your body
in many ways to cause an allergic reaction. 2 Examples of
allergens include pollen, dust, mould, and animal dander.
In an attempt to protect your body, your immune system produces
antibodies that cause specific cells in your body to release
histamine into your bloodstream.

life-threatening reaction called anaphylaxis, which can be
fatal. 5
How Should Allergies Be Treated?
Allergy treatment often includes 3 treatment types: avoiding allergens, medication, and/or immunotherapy (which involves receiving an allergen via a shot or under the tongue). 4 Ultimately, the best way to avoid allergic reactions is to stay away from the substances/allergens that cause them. 4 You can also use over-the-counter medications like Telfast® or consult with your healthcare professional.
