Are you a candidate for allergy drops? Allergy drops are known as sublingual immunotherapy or S.L.I.T. and are administered as a daily drop under your tongue, instead of by an injection. The area under your tongue has the highest concentration of antigen-presenting cells found in the body. Because these cells are involved in twp types of immune responses, delivering daily allergy drops consistently to this area allows your immune system to increase tolerance to your trigger allergens. Most allergy sufferers can benefit from allergy drops. This type of immunotherapy is especially great for patients who can’t tolerate or don’t respond to allergy injections, as well as those who can’t make the scheduled office visits required for allergy injection treatment. Allergy drops are administered at home, so you don’t have the frequent clinic visits and discomfort associated with injections.
