Today I visited my neighbor's house, and noticed a red rash on their face. Not knowing what caused it, my mother said it might be a symptom of sublingual immunotherapy for allergic urticaria. The neighbor mentioned that the rash has been present for a long time and hasn't improved, so they are quite confused and would like to understand how to manage sublingual immunotherapy for allergic urticaria.

Sublingual immunotherapy for allergic urticaria primarily aims to reduce or eliminate allergic reactions by gradually desensitizing patients to the allergens. The specific steps are as follows: 1. Identify the allergen: Determine the specific allergen causing allergic urticaria, such as house dust mites, pollen, etc. 2. Prepare the allergen solution: Prepare the allergen into solutions of varying concentrations, ensuring administration starts with a low concentration. 3. Sublingual administration: The patient places the allergen solution under the tongue, holds it there for 1–3 minutes, and then swallows. Treatment begins with a small dose, gradually increasing both dose and concentration to enhance the patient's tolerance. 4. Continuous treatment: Sublingual immunotherapy typically requires a long duration, possibly lasting several months to years, to ensure the patient achieves long-term tolerance to the allergen. 5. Precautions: During treatment, patients must follow medical instructions, take medication regularly, and monitor changes in their condition. If any adverse symptoms occur, they should seek medical attention promptly. Through sublingual immunotherapy, patients with allergic urticaria can gradually adapt to allergens, reduce the frequency of allergic reactions, and improve their quality of life.
