It seems as if every month, I see another study on the safety and benefits of allergy drops, also called sublingual immunotherapy (SLIT). SLIT has yet to be approved for use in the United States, but typically uses the same allergy extracts as those used for traditional allergy shots. SLIT is placed under the tongue, typically on a daily basis, and is usually given at home. While allergy shots are very safe, these treatments must be given in a doctor's office given the small chance of a serious allergic reaction.

SLIT is the preferred method of immunotherapy in Europe, and (once approved in the U.S) should be a welcome alternative to allergy shots, especially for those people with a severe fear of needles or a busy schedule that prevents regular trips to the allergist's office to get their allergy shots.
