Once allergy has been diagnosed by the allergologist, the next step is symptom reduction to a minimum by avoiding the allergen as much as possible and by finding the best matching treatment. In most cases patients with an allergy require more than just avoiding exposure to the allergen. Often people with allergies will need to take medication to control their condition.

The key elements of treatment of allergic disease are to do the following without causing excess side effects: reduce symptoms, minimize restrictions in lifestyle, improve quality of life (QoL) and reduce time lost from school and work.
