Allergy

The initial step in the treatment of an allergy is an accurate diagnosis by an otolaryngic allergist (ENT). It involves deciding whether the patient’s symptoms are caused by an allergy and, if so, determining what triggers the allergy as accurately as possible. The resulting diagnosis will target the appropriate treatment or clinical intervention to allow avoidance of the allergic trigger which will help to eliminate or minimize symptoms.

An accurate diagnosis is obtained using a combination of approaches and tests that can include skin-pricks and blood tests to identify and confirm a diagnosis. Treatments can include:

Control of Symptoms

These treatments can be self-administered and do not necessarily need to be based on an accurate diagnosis. Examples include the use of over the counter medications such as antihistamine creams and steroid creams for eczema and antihistamine pills for nasal symptoms that include rhinitis. More serious conditions can be treated with inhalers for asthma, skin creams for eczema and auto injectors for anaphylaxis resulting from, among other causes, insect bites, without having identified whether the condition is truly an allergy.

Avoiding Allergens

This approach is used mainly for allergies caused by food, drugs, venom, latex and animal dander. This can also include occupational allergies, and to a lesser extent, depending on the suspected cause, asthma, rhinitis and eczema. When using allergen avoidance, it is important to know that there may be interactions resulting from cross reactions between, to name a few, latex and fruits and vegetables as well as tree pollen and fresh fruits. While it may appear simple, avoiding allergens may be difficult to achieve, costly and may not be completely successful.

Rescue Medications

This approach is often part of an individual’s emergency self-treatment plan for acute attacks such as for acute tongue swelling or anaphylaxis that can result from insect bites.

Immunotherapy

By administering an allergen either via a beneath the skin (subcutaneous) injection or under the tongue (sublingual) an allergist or immunologist can try to reintroduce a patient’s immunological tolerance to a particular allergen. These procedures are typically used to treat allergies caused by pollen rhinitis, venom, asthma and cat allergy. On occasion, the use of drugs to desensitize a patient to a particular allergen can also be used.
