Palforzia is indicated for the treatment of peanut allergy in patients aged 4 to 17 years. It is intended to reduce the risk and severity of allergic reactions that may occur from accidental exposure to peanuts. It is not a cure for peanut allergy and does not treat allergic reactions once they occur.
Palforzia contains peanut protein and works through oral immunotherapy. Patients consume daily doses of peanut protein powder, starting with very small amounts and gradually increasing the dose under medical supervision. This controlled exposure over time helps desensitize the immune system, building tolerance to peanut allergens and reducing the severity of allergic reactions from accidental exposure.
Initial dose escalation and the first dose of each new maintenance level must be administered in a certified healthcare facility equipped to manage severe allergic reactions. Patients must continue avoiding peanuts in their diet overall—Palforzia is not a substitute for peanut avoidance. Common side effects may include abdominal pain, itching, and oral irritation. Patients should always carry epinephrine for emergency treatment of allergic reactions. Dosing must not be stopped without medical consultation.
