Patients may schedule an appointment with our office for these services, or contact their family doctor. Allergen immunotherapy is a form of treatmen

t aimed at decreasing your sensitivity to

substances called allergens. Th

ese allergens are identified by allergy testing, and are

the substances that trigger your allergy

symptoms when you ar

e exposed to them.

Allergen immunotherapy involves

injecting increasing amounts

of an allergen to a patient

over several months. Immunotherapy has be

en shown to prevent the development of

new allergies and, in children, it can prevent the progression

of the allergic disease from

allergic rhinitis to as

thma. Allergen immunother

apy can lead to the long-lasting relief of

allergy symptoms after tr

eatment is stopped.
