Used for the diagnosis of marshelder pollen allergies via skin prick testing and for allergen immunotherapy (desensitization treatment) in patients with allergic rhinitis, conjunctivitis, or allergic asthma triggered by marshelder pollen exposure.
The extract contains antigenic proteins from marshelder pollen that stimulate the immune system when administered in gradually increasing doses, promoting the production of blocking antibodies and reducing IgE-mediated hypersensitivity reactions over time.
Should only be administered by healthcare providers trained in allergen immunotherapy with emergency equipment readily available due to risk of anaphylaxis. Not indicated for patients with severe uncontrolled asthma or certain cardiac conditions. Initial dosing must follow established protocols with observation period after each administration.
