Under-the-Tongue Immunotherapy Tablets

Under-the-tongue, or sublingual immunotherapy (SLIT) allergy tablets are a new FDA-approved therapy for patients allergic to grass or ragweed pollen. Similar tablets are being developed for dust mites and other inhaled allergens.

Instructions vary among the different products, but the basic procedure is for the patient to take one tablet a day, beginning 3-4 months before their allergy season begins. The therapy continues on through the allergy season to prevent sneezing, nasal congestion, nasal itching, runny nose and itchy/watery eyes.

Unlike allergy shots, SLIT tablets may not offer long-term protection and generally must be taken each year before and during allergy season.

After receiving the first dose at the doctor’s office, patients can then take the tablets at home – as long as there are epinephrine auto-injectors available to treat potential anaphylaxis, which is possible according to the warning in the package insert.
