How Do Allergy Drops Work?
Allergy drops work similar to allergy shots by delivering a slowly increasing dose of physician-prescribed, FDA-approved antigen that over time helps you build a tolerance to the things you are allergic to.
The difference is that the drops are placed under the tongue and affect the immune system through very specialized (dendritic) cells found under the tongue. Research shows these cells are a friendlier, effective, and safe route for long-term allergen tolerance, making it an ideal option for patients who aren’t candidates for shots.
Administering the allergy drops multiple times per day is a key factor effecting treatment outcomes.1 In clinical trials, researchers saw additional immunological changes as the course of treatment progressed2, so while you may feel better in the short-term, the average course of allergy drop treatment is three to five years. It is necessary to follow your doctor’s instructions until they determine treatment is complete in order to change the underlying allergic disease.
