Used to diagnose Arizona Ash pollen allergy through skin prick testing and to treat allergic conditions caused by Arizona Ash pollen exposure, including allergic rhinitis (hay fever), rhinoconjunctivitis, and associated respiratory symptoms. Indicated for patients with clinically confirmed IgE-mediated sensitivity to Arizona Ash pollen.
Contains standardized extracts of Arizona Ash tree pollen allergens. During immunotherapy, repeated controlled exposure to the allergen modifies the immune response, reducing IgE antibody production and increasing allergen-specific IgG 'blocking' antibodies. This leads to decreased mast cell activation and histamine release upon natural pollen exposure, resulting in fewer allergic symptoms over time.
Must be prescribed and initiated under medical supervision, typically by an allergist/immunologist. Initial dosing requires observation for potential anaphylactic reactions. Contraindicated in patients with severe asthma, cardiovascular disease, or certain immune disorders. Treatment efficacy develops gradually over months to years of consistent administration. Local reactions at administration site are common; systemic reactions require immediate medical attention.
