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.
......
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.
......
The prescribing information includes a boxed warning that severe allergic reactions (such as anaphylaxis, which can be life-threatening) can occur. Oralair also has a medication guide for distribution to the patient. The most common adverse reactions reported by adults were itching in the ears and mouth and of the tongue, as well as swelling of the mouth and throat irritation. In children, the most commonly reported adverse reactions were itching and swelling in the mouth and throat irritation.
......
Oralair is manufactured by Stallergenes S.A. of Antony, France.
