Allergy drops are an alternative to allergy shots. While allergy shots are placed beneath the skin using an injection, allergy drops are taken by mouth. Allergy drops are placed under the tongue and are known as “sublingual immunotherapy” (SLIT).
Your allergy drops will come in pill or liquid form. Both versions contain a small amount of your specific allergen. You will place the pill or liquid beneath your tongue each day and wait for it to dissolve.
When our bodies are exposed to a large quantity of an allergen, our immune system tries to clear it away. This is what causes symptoms such as sneezing, nasal drainage, and watery eyes.
Immunotherapy works by repeatedly exposing you to small amounts of the allergen, which gradually increase. This works to decrease your sensitivity, even when exposed to larger quantities of the allergen.
