Used for the diagnosis and treatment of allergic rhinitis, conjunctivitis, and asthma triggered by Fremont cottonwood pollen exposure. Indicated for patients with confirmed sensitivity to Populus species pollen who have not responded adequately to conventional antihistamine or nasal corticosteroid therapies.
The mechanism is not fully specified, but allergen extracts work by exposing the immune system to gradually increasing doses of the allergen, promoting immune tolerance over time. This process aims to reduce IgE-mediated hypersensitivity reactions and decrease the release of inflammatory mediators like histamine upon subsequent natural exposure.
Administration should only be performed by qualified healthcare providers trained in allergen immunotherapy due to risk of severe allergic reactions including anaphylaxis. Requires appropriate emergency equipment and medications on-site. Treatment typically begins with low doses with gradual escalation. Contraindicated in patients with severe asthma, cardiovascular disease, or who are taking beta-blockers. Local reactions at injection site are common; systemic reactions require immediate medical intervention.
