What Is Sublingual Immunotherapy?
Sublingual immunotherapy (SLIT) is an innovative allergy treatment that reduces sensitivity to allergens such as dust mites, pollen, and mold. Instead of injections, SLIT uses small dissolvable tablets or drops placed under the tongue. Over time, the immune system becomes less reactive, reducing symptoms and long-term dependence on medication.
How Sublingual Immunotherapy Works
SLIT gradually exposes the body to allergens in controlled amounts. The mouth’s immune tissues absorb the allergen and teach the body to tolerate it instead of reacting strongly. This process reduces inflammation, nasal congestion, sneezing, and itching. Compared to allergy shots, sublingual immunotherapy offers convenience because it can be taken at home after the initial supervised dose.
Benefits of Sublingual Immunotherapy
SLIT is ideal for individuals with dust mite allergies, pollen allergies, and mild asthma triggered by allergens. It is safer than injections because it carries a lower risk of severe allergic reactions. Patients also appreciate its painless and non-invasive nature. Sublingual immunotherapy treats the root cause of allergies rather than just relieving symptoms, leading to long-term improvement.
Who Should Consider SLIT?
Individuals with chronic allergic rhinitis or those seeking long-term control without frequent clinic visits benefit greatly from sublingual immunotherapy. A consultation with an allergy specialist can determine the correct dosage and duration. Most treatments last 3–5 years, building strong and lasting immune tolerance. SLIT provides an effective pathway to a healthier, allergy-free life.
