The U.S. Food and Drug Administration today approved Ragwitek, the first allergen extract administered under the tongue (sublingually) to treat short ragweed pollen induced allergic rhinitis (hay fever), with or without conjunctivitis (eye inflammation), in adults 18 years through 65 years of age.
Ragwitek contains an extract from short ragweed (Ambrosia artemisiifolia) pollen. It is a tablet that is taken once daily by placing it sublingually, where it rapidly dissolves. Treatment with Ragwitek is started 12 weeks before the start of ragweed pollen season and continued throughout the season. The first dose is taken in a health care professional’s office where the patient is to be observed for at least 30 minutes for potential adverse reactions. After the first dose, patients can take Ragwitek at home.
