Sublingual Immunotherapy Research
The AllergyEasy program offers the thorough protection of its Comprehensive Allergy Serum. (Rather than just containing a few local pollens, it contains most common antigens from around the world).
This is coupled with the proven benefits of sublingual immunotherapy (SLIT). Not only is SLIT highly convenient since it can be taken at home, it has also been proven to be effective and safer than allergy shots.
The Cochrane Collaboration (internationally recognized as the highest standard in evidence-based health care) reviewed 22 studies involving 979 patients using SLIT and concluded that SLIT is a safe treatment which reduces symptoms and medication requirements in allergic rhinitis. SLIT is widely used in Europe where it accounts for at least 45 percent of allergy treatment. SLIT is affirmed by the World Health Organization and ARIA guidelines (Allergic Rhinitis and its Impact on Asthma).

Sublingual Immunotherapy for Environmental Allergies
Allergen-Specific Immunotherapy for Pediatric Asthma and Rhinoconjunctivitis: A Systematic Review
Pediatrics: Official Journal of the American Academy of Pediatrics, 2013
Evidence supports the efficacy of both SCIT and SLIT for the treatment of asthma and rhinitis in children.
Sublingual Immunotherapy for Allergic Rhinitis and Conjunctivitis
SLIT has been consistently shown to be capable of reducing symptoms and medication use in allergic rhinitis and possibly in coexistent asthma for all the relevant allergens. In addition, due to the complex mechanism of action, SLIT profoundly modifies the immune response, thus, its effects last for many years. Finally, SLIT,* as well as SCIT, ** can reduce the risk of asthma onset in children with allergic rhinitis. According to this evidence, SLIT is confirmed to be a viable alternative to SCIT in the treatment of allergic rhinoconjunctivitis, with a very favorable safety profile and the possibility of expanding the indications to other diseases.
Efficacy of Sublingual Immunotherapy Versus Subcutaneous Injection Immunotherapy in Allergic Patients
Journal of Environmental and Public Health, 2012
These results suggest that SCIT and SLIT exhibit similar efficacy. SLIT objectively improves symptom scores for asthma and allergic rhinitis while decreasing medication usage of allergy medications. Given the increased risk and difficulty in treating asthmatic and young patients, these results would suggest that SLIT should be considered as the main treatment modality for these patients, considering SCIT only for treatment failures.
Quality of Life Improvement with Sublingual Immunotherapy: A Prospective Study of Efficacy
Journal of Allergy, 2012
Statistically significant reduction of symptoms and improvement of quality of life are demonstrated during the initial four month period of SLIT. After the first four months, reduction of symptom scores is sustained and continuous.
Allergen Immunotherapy in Allergic Respiratory Disease: From Mechanisms to Meta-Analyses
Chest Journal: Official Publication of the American College of Chest Physicians, 2012
Sublingual immunotherapy is generally well tolerated, with local side effects (perioral and oral itching or mild swelling) experienced in approximately three-fourths of patients. To our knowledge, only six cases of anaphylaxis to SLIT have been reported thus far. A health economics analysis of SLIT against pharmacotherapy has been performed for pollen and mite allergens and found SLIT to be cost-effective as well.
High-Dose Sublingual Immunotherapy with Single-Dose Aqueous Grass Pollen Extract in Children is Effective and Safe: A Double-Blind, Placebo-Controlled Study
Journal of Allergy and Clinical Immunology, 2012
This study confirmed that this SLIT preparation significantly reduced symptoms and medication use in children with grass pollen-allergic rhinoconjunctivitis. The preparation showed significant effects on allergen-specific antibodies was well tolerated and appeared to be a valid therapeutic option in children allergic to grass pollen.

The Current Role of Sublingual Immunotherapy in the Treatment of Allergic Rhinitis in Adults and Children
Journal of Asthma and Allergy, 2011
SLIT has gained ample evidence of efficacy and safety and in some European countries is currently used more frequently than SCIT. Apart from its better safety profile, the advantages of SLIT over SCIT are with regard to compliance, which is higher because SLIT does not need to be administered in a medical setting, and cost-effectiveness, because the cost of the injections is not involved.
Sublingual Immunotherapy in Allergic Rhinitis
Asia Pacific Allergy, 2011
Sublingual immunotherapy (SLIT) has been widely used in European countries replacing SCIT because SLIT has several advantages: noninvasiveness, home administration, less frequency of severe adverse reaction than SCIT. The efficacy and safety of SLIT have been studied and in 2008, British Society for Allergy and Clinical Immunology announced SLIT as safe immunotherapy for AR and asthma and in 2009, World Allergy Organization Position Paper about SLIT described its efficacy and safety.
Safety of Sublingual Immunotherapy
Journal of Biological Regulators and Homeostatic Agents, 2011
Sublingual immunotherapy (SLIT) is now recognized as a viable alternative to the classical injection route and it is currently used in everyday clinical practice in Europe. Sublingual administration is particularly attractive for children since it is completely pain-free. To date, no fatalities from SLIT have been reported, but two cases of anaphylaxis to inhalant allergens have been reported. The large majority of the adverse events reported in literature is described as mild.
Sublingual Immunotherapy for Allergic Rhinitis
Cochrane Database of Systematic Reviews, 2010
SLIT is a safe treatment which significantly reduces symptoms and medication requirements in allergic rhinitis.
Sublingual Immunotherapy: Clinical Indications in the WAO-SLIT Position Paper
World Allergy Organization Journal, 2010
SLIT is certainly indicated in allergic rhinitis in both adults and children. In this latter population, SLIT may exert a preventative effect on the development of asthma. The age seems not to represent a special problem. SLIT can be used also when asthma is associated to rhinitis, whereas it is not the first choice for the treatment of isolated asthma. The safety profile is excellent, but it is recommended that the first dose be given under medical supervision.
Undertreatment of Allergy: Exploring the Utility of Sublingual Immunotherapy
Otolaryngology-Head and Neck Surgery, 2009
Conventional subcutaneous immunotherapy is effective but is also associated with a risk of serious adverse events, requires administration by a trained health care professional, and is contraindicated in certain populations. By contrast, sublingual immunotherapy has been used extensively in Europe and possesses most of the benefits of subcutaneous immunotherapy along with increased safety, tolerability, and convenience. This narrative review explores data from selected clinical studies and concludes that sublingual immunotherapy may be well suited to fill the gap posed by the undertreatment of allergic syndromes in the United States.

Sublingual Immunotherapy: What Have We Learned From the ‘Big Trials’?
Current Opinion in Allergy and Clinical Immunology, 2008
Sublingual immunotherapy represents an effective and well tolerated treatment for seasonal allergic rhinoconjunctivitis in adults. Current ongoing pediatric trials and evaluation of long-term effects in adults will further define its role in therapy.
Effects of Sublingual Immunotherapy on Allergic Inflammation
Inflammation and Allergy Drug Targets, 2008
Allergen specific immunotherapy (AIT) has a recognized impact on allergic inflammation, which persists after its discontinuation, and is the only therapy able to modify the natural history of allergic march. Anti-inflammatory mechanisms observed during sublingual immunotherapy with high allergen doses proved to be similar compared to subcutaneous immunotherapy. Recent data obtained in biopsies clearly indicate that the pathophysiology of the oral mucosa, and in particular mucosal dendritic cells, plays a pivotal role in inducing tolerance to the administered allergen.
Sublingual Immunotherapy: Past, Present, Paradigm for the future? A Review of the Literature

Sublingual Immunotherapy for Food Allergies
Sublingual Immunotherapy for Peanut Allergy: A Randomized, Double-Blind, Placebo-Controlled Multicenter Trial
The Journal of Allergy and Clinical Immunology, 2013
Peanut SLIT safely induced a modest level of desensitization in a majority of subjects compared with placebo. Longer duration of therapy showed statistically significant increases in the successfully consumed doses.
Sublingual vs. Oral Immunotherapy for Food Allergy: Identifying the Right Approach
Allergen immunotherapy is currently being studied for use in the treatment of IgE-mediated food allergy to the most common foods, including peanut, tree nut, milk and egg. Two modalities, oral immunotherapy (OIT) and sublingual immunotherapy (SLIT), have shown great promise. Both OIT and SLIT have been able to desensitize subjects to varying degrees, but the two treatment methods differ in doses that can be achieved, duration of treatment, safety profile and ease of use outside the research setting, among other aspects. OIT and SLIT show great promise, and a widespread treatment for food allergy may be within reach.
Can a Radical New Treatment Save Children With Severe Food Allergies?
The New York Times, 2013
Dr. Kari Nadeau, Associate Professor of Allergies and Immunology at Stanford University School of Medicine, is conducting a trial to desensitize children with multiple food allergies.
Sublingual Immunotherapy for Peanut Allergy: Clinical and Immunologic Evidence of Desensitization
The Journal of Allergy and Clinical Immunology, 2010
Peanut SLIT is able to safely induce clinical desensitization in children with peanut allergy, with evidence of immunologic changes suggesting a significant change in the allergic response. Further study is required to determine whether continued peanut SLIT is able to induce long-term immune tolerance.
