Allergen immunotherapy is a treatment that helps re-train your immune system to be less reactive to a specific allergen. It involves regular exposure to tiny, precisely measured doses of the allergen over time.
How it’s given: either tablets/drops under the tongue (SLIT) taken at home after the first supervised dose, or injections in clinic (SCIT) at set intervals.
Who it’s for: most often used for hay fever (pollens), house-dust mite, pet dander, and insect venom allergy. It’s not typically used for most food allergies.
Benefits: can reduce symptoms and medication use and may have long-term, disease-modifying effects after a typical 3-year course.
Safety & suitability: not everyone is a candidate; your clinician will assess you. Side-effects are usually mild; supervised care keeps the process safe.
