Sublingual Allergy Tablets Are an Effective Treatment for Allergies

Individuals with allergies to grass, ragweed and/or dust mites may benefit from sublingual allergy tablets available by prescription from an allergist.

Sublingual allergy tablets have been used in Europe for several years. In recent years they were made available in the United States. For some patients, sublingual allergy tablets are an effective alternative to allergy shots.

According to Dr. Reynold Karr, an allergy and immunology specialist at the University of Washington Medical Center, the treatment involves placing an allergen tablet, such as one consisting of purified grass pollen, under the tongue each day at home.

“The tablet dissolves in seconds and the risk of a severe allergic reaction is very small,” Dr. Karr said.

When to Begin Sublingual Allergy Tablet Treatment

For grass and ragweed allergies, treatment is seasonal and should be started 12 weeks before your particular pollen season begins. Timing is critical, so it’s important to see your allergist at least four months before your allergy season begins. Allergy testing to confirm your sensitivities may be performed. Your doctor will direct you on when to begin taking your treatment based on your community’s pollen count history.

Sublingual treatment for dust mites is year-round.

Successfully Using Sublingual Allergy Tablets

When using sublingual immunotherapy for allergies, it’s important to place the tablet underneath your tongue and allow it to dissolve completely. Why? If you simply swallow the pill, the purified pollen will be destroyed by the digestion process. In placing the tablet underneath your tongue, the immunotherapy is distributed directly into your sublingual vein located in the floor of your mouth.

There are pros and cons to using sublingual immunotherapy to treat allergies. Side effects among children and adults are usually local and mild. Your allergist will guide you in your treatment plan.
