What are allergy tablets?

Donna Hill Howes, RN
Family Practitioner

Allergy tablets are a form of immunotherapy. Immunotherapy tells your immune system to make you less sensitive to certain allergens, such as pollen. Allergy tablets are placed under your tongue and allowed to dissolve. They are taken daily. They are not meant to relieve your allergy symptoms right away.

The FDA has approved 2 types of allergy tablets for grass pollen called Oralair and Grastek. Oralair contains 5 kinds of northern grass pollen. Grastek contains Timothy grass pollen. The FDA has also approved Ragwitek for short ragweed pollen.
