A Patient’s Guide to Sub-Lingual Immunotherapy (SLIT)

Sublingual immunotherapy, or SLIT, is an alternative treatment for allergies, where the allergen is administered under the tongue rather than through injection. The treatment involves placing small doses of the allergen, typically in liquid or tablet form, beneath the tongue to help the body gradually build tolerance. The immune system is slowly reconditioned to recognizing these allergens, thereby reducing the severity of allergic reactions.

The specialists at Allergy and Asthma Care may recommend SLIT as an option for individuals who want a convenient, non-invasive form of immunotherapy. By taking these allergens in small, controlled daily doses, the patient’s immune system is gradually trained to respond less intensely. While the exact mechanism behind the success of SLIT is still being researched, studies strongly suggest that it alters the immune system’s response at a cellular level, eliminating danger, relieving discomfort and leading to long-term tolerance.

SLIT is commonly used to treat a variety of allergic conditions. These include various foods, allergic rhinitis (hay fever), asthma triggered by allergens, and conjunctivitis caused by environmental factors like dust mites, grass, or ragweed pollen. SLIT is particularly beneficial for patients whose symptoms are persistent throughout the year or for those whose exposure to allergens, such as pet dander, is difficult to avoid. The specialists at Allergy and Asthma Care can determine the most suitable candidates for SLIT. In some cases, SLIT can even reduce the need for medications that control allergy symptoms offering patients long-term relief from the discomfort of allergic reactions. As with any treatment, the effectiveness of SLIT can vary by the individual and the specific allergen involved.

SLIT can benefit a wide range of individuals who suffer from allergic rhinitis, asthma, or conjunctivitis triggered by allergens. It is particularly helpful among patients with environmental allergies who are looking for a long-term solution to their allergies and who are either unable or unwilling to undergo traditional allergy shots. Individuals with needle phobia, those seeking an at-home treatment option, young children and the elderly may find SLIT to be a more convenient and less invasive option compared to injection-based immunotherapy.

SLIT can also be an excellent option for patients with severe food allergies who are not willing or able to undergo Oral Immunotherapy (OIT). Some patients are so highly allergic that it is advisable to start the desensitization process with SLIT as a bridge to OIT or as a standalone treatment for the allergy. In general, treatment with SLIT is easier to accomplish and has fewer potential side effects than OIT.

The experts at Allergy and Asthma Care may also recommend SLIT for individuals with chronic allergy symptoms seeking a preventive approach rather than relying solely on medications to manage their condition. Patients must, however, be carefully assessed to determine if SLIT is the right fit, as not everyone will be an acceptable candidate for this treatment.

As with all medical treatments, Sublingual Immunotherapy carries potential side effects, though they are generally transient and mild. The most common reactions are localized to the mouth and throat, including itching, swelling, or irritation under the tongue. These symptoms usually resolve on their own shortly after the treatment is administered. More intense allergic reactions may potentially occur, but they are significantly less common compared to injection-based immunotherapy.

The specialists at Allergy and Asthma Care will closely monitor patients during the early stages of SLIT to ensure proper, safe response to the treatment. While most side effects are minor, it is essential for patients to report any concerning reactions to their provider. With proper medical oversight, SLIT is considered a safe and effective treatment option for many individuals managing allergic conditions.
