Treatment of patients with documented systemic allergic reactions to paper wasp stings, particularly those with history of anaphylaxis or severe allergic responses to Hymenoptera venom. Typically prescribed after allergy testing confirms specific IgE sensitization.
As an allergen immunotherapy product, it works by administering gradually increasing doses of paper wasp venom to induce immune tolerance. Over time, this reduces the severity of allergic reactions upon future natural stings by modifying the immune response.
Must be administered under medical supervision in settings equipped for emergency treatment of anaphylaxis. Initial build-up phase requires frequent visits, followed by maintenance doses. Contraindicated in patients with certain cardiovascular conditions. Common side effects include local injection site reactions and, less commonly, systemic allergic symptoms.
