FDA approves first sublingual allergen extract

FDA approves first sublingual allergen extract for the treatment of certain grass pollen allergies.

“The U.S. Food and Drug Administration recently approved Oralair to treat allergic rhinitis (hay fever) with or without conjunctivitis (eye inflammation) that is induced by certain grass pollens in people ages 10 through 65 years. Oralair is the first sublingual (under the tongue) allergen extract approved in the United States. After administration of the first dose at the health care provider’s office, where the patient can be observed for potential adverse reactions, Oralair can be taken at home.

“While there is no cure for grass pollen allergies, they can be managed through treatment and avoiding exposure to the pollen,” said Karen Midthun, M.D., director of the FDA’s Center for Biologics Evaluation and Research. “The approval of Oralair provides an alternative to allergy shots that must be given in a health care provider’s office. Oralair can be taken at home after the first administration.”
Oralair is a once-daily tablet that rapidly dissolves after it is placed under the tongue. Oralair is started four months before the start of the grass pollen season and continued throughout the season. The first dose is taken at the health care provider’s office, where the patient is to be observed for at least 30 minutes for potential adverse reactions.
Oralair contains a mixture of freeze-dried extracts from the pollens of five grasses, including Kentucky Blue Grass, Orchard, Perennial Rye, Sweet Vernal and Timothy.”
