Sublingual Immunotherapy

Patients who suffer from allergies understand the impact it can have on their lives. Whether suffering from rhinitis (hay fever), or asthma, allergies can cause everyday life to be uncomfortable. Sublingual immunotherapy has been shown to be effective and safe for the treatment of hay fever and asthma caused by allergies to grass, ragweed, dust mites, cat dander, and tree pollens.

What is Sublingual Immunotherapy?

Sublingual immunotherapy (SLIT) is an alternative to treating allergies without injections. This can be great for patients or children who do not do well with needles or simply wish to avoid them.

SLIT is available in two main forms: tablets and liquid drops. The FDA (Food and Drug Administration) has approved only certain SLIT tablets for allergens such as ragweed and grass pollen, and these allergy tablets are covered by most insurance plans. Drug administration: FDA approval is required for insurance coverage of these treatments. In contrast, SLIT allergy drops (liquid formulations) are used off-label, are not currently approved by the FDA, and are not covered by most insurance, Medicare, or Medicaid.

Some medical professionals can use SLIT to treat allergies to food allergens such as peanut, kiwi, hazelnut, milk, and peach, although it is not widely available for food allergies. Peanut SLIT, for example, has been studied for its safety and effectiveness in treating peanut allergy.

Benefits of Sublingual Immunotherapy

Sublingual immunotherapy (SLIT) offers a range of benefits for individuals struggling with allergies, including allergic rhinitis, allergic asthma, and even certain food allergies. One of the most significant advantages of SLIT is that it provides relief from allergy symptoms without the need for frequent allergy shots. Instead of injections, patients simply place a small amount of allergen extract under the tongue, making the process much more comfortable, especially for children or anyone who prefers to avoid needles.

SLIT is designed to help the body gradually build tolerance to specific allergens, such as dust mites, grass pollen, or house dust. By exposing the immune system to these allergens in smaller doses, the severity of allergic reactions can be reduced over time. This approach is particularly helpful for people with multiple allergies or those who have experienced severe allergic reactions in the past, as SLIT allows for targeted treatment with a lower risk of adverse reactions.

Convenience is another key benefit of sublingual immunotherapy. Unlike subcutaneous immunotherapy (allergy shots) or frequent use of nasal sprays, SLIT can be administered at home, saving patients time and reducing the need for regular doctor visits. This is especially valuable for busy families, younger children, or those living far from specialized allergy clinics.

SLIT has proven effective in treating a variety of airborne allergens, including those responsible for hay fever, such as grass pollen and dust mites. Patients often notice a reduction in symptoms like sneezing, itching, and nasal congestion. Additionally, SLIT is being used to treat certain food allergies, such as peanut allergies, with promising results in increasing food tolerance and reducing the risk of severe reactions in children.

The treatment process typically begins with an escalation phase, where the dose of allergen extract is gradually increased to help the body adjust. This is followed by a maintenance phase, during which patients continue daily dosing for up to three to five years to achieve lasting results. Most patients tolerate SLIT well, with only mild side effects like an itchy mouth or throat. However, as with any allergy treatment, there is a small risk of more serious reactions, so it’s important to follow your allergist’s instructions and report any concerns.

Overall, sublingual immunotherapy provides an effective, convenient, and safe alternative for those looking to treat allergies and reduce their reliance on medications like antihistamines and allergy tablets. By targeting the underlying cause of allergic symptoms, SLIT can help patients achieve long-term relief and a better quality of life. As research continues and more treatments become FDA-approved, SLIT is likely to become an increasingly popular choice for allergy management.

How is Sublingual Immunotherapy Done?

Before SLIT can be done, allergy testing must be done to confirm your sensitivities. Once the allergens have been identified, an allergen extract is prepared in tablet or drop form. The first dose of SLIT is often administered under medical supervision to monitor for any adverse reactions. During the first 10 weeks of sublingual immunotherapy, the daily dose is gradually increased, starting from a diluted dose and reaching full strength, to help build tolerance to the allergen. Patients will need to take the drop or tablet as directed by their physician and continue for up to three to five years to strengthen the body’s immunity. Follow-up office visits for SLIT may be covered by insurance, depending on your plan.

Sublingual Immunotherapy Recovery

Many patients do not experience any side effects associated with SLIT. However, if side effects do occur, the most common are mild and include slight itching or tingling in the mouth, lips, or throat, especially during the first couple of weeks. The primary side effects of allergy tablets are local reactions such as itching or burning of the mouth or lips, and less commonly, gastrointestinal symptoms. Rarely, eosinophilic esophagitis, a rare allergic reaction in the esophagus that can mimic symptoms like heartburn or difficulty swallowing, may occur.

The FDA-approved product information for the four SLIT tablets includes a warning about the possibility of severe allergic reactions. Although severe allergic reactions are rare, patients should be prepared to respond to a severe reaction by using an epinephrine auto-injector and calling 911 if necessary. Because SLIT treatment is administered at home without medical supervision, patients should be aware of how to manage possible adverse reactions to the treatment.

If you or a loved one is suffering from allergies that disrupt their quality of life, sublingual immunotherapy may be able to help. Not only has this treatment been shown to be effective in controlling allergy symptoms, but it has also been shown to provide long-term improvement.
