SUBLINGUAL IMMUNOTHERAPY FOR ALLERGIES

An allergy shot is a type of immunotherapy. Sublingual immunotherapy is a type of immunotherapy in which the patient places a tablet or liquid dose under the tongue once a day to help prevent and ultimately reduce or eliminate a reaction to a specific allergen. It works by exposing the patient to a small amount of the allergen each day to help them slowly build a tolerance safely and effectively. Putting the allergen under the tongue allows the mucus membranes in the mouth to deliver the substance directly to the bloodstream. Sublingual immunotherapy is currently used to treat seasonal allergies like hay fever and dust mite allergies, but it’s also beginning to become available for food allergens like peanuts.

P.S. Sublingual immunotherapy is less likely to cause a severe reaction and may reduce asthma symptoms in some patients.
