Allergy DropsAlthough in its experimental stage, sublingual allergy drops are gaining attention as an alternative to immunotherapy injections. Also known as sublingual/swallow immunotherapy, or SLIT, these drops work much like allergy shots -- a weakened dose of allergen extract is introduced and, it is hoped, the body builds up immunity. Unlike shots, no needle is involved, and you don't need to visit the doctor's office on a regular basis to receive treatment. Instead, the patient is given a small vial of allergens and places drops under the tongue three times a day. SLIT treatment is controversial in the United States and has not been approved by the Food and Drug Administration (FDA), although it has been approved in many countries in Europe. Few allergists in the United States use or recommend SLIT treatment; most are awaiting further studies on its comparative efficacy as well as patient follow-through.
