Sublingual is the medical term for “under the tongue.” Immunotherapy is
a type of preventative treatment for an allergic response to allergens such
as pollens, dust mites, molds, and animal dander. Immunotherapy treats
the underlying cause of the allergic reaction while decongestants and antihistamines only treat the symptoms. Immunotherapy involves administering gradually increasing doses of the allergen to the allergic patient. The gradual introduction of the allergens induces a natural immunity or tolerance. This reduces the patient's allergic reactions without medications.

Until recently, the only way to administer these doses in the United States was by injections or allergy shots at the doctor’s office.

Sublingual Immunotherapy is an injection-free procedure that offers the patients the freedom to treat their allergies on their schedules in their homes.
