Patients who have persistent and escalating adverse reactions in the mouth or throat should be considered for discontinuation of ODACTRA.

Eosinophilic esophagitis has been reported in association with sublingual tablet immunotherapy. Discontinue ODACTRA and consider a diagnosis of eosinophilic esophagitis in patients who experience severe or persistent gastro-esophageal symptoms including dysphagia or chest pain.

Withhold immunotherapy with ODACTRA if the patient is experiencing an acute asthma exacerbation. Re-evaluate patients who have recurrent asthma exacerbations and consider discontinuation of ODACTRA.

ODACTRA has not been studied in subjects who are receiving concomitant allergen immunotherapy. Concomitant dosing with other allergen immunotherapy may increase the likelihood of local or systemic adverse reactions to either subcutaneous or sublingual allergen immunotherapy.

Stop treatment with ODACTRA to allow complete healing of the oral cavity in patients with oral inflammation (e.g., oral lichen planus, mouth ulcers, or thrush) or oral wounds, such as those following oral surgery or dental extraction.

The most common solicited adverse reactions reported in clinical studies for subjects 18 through 65 years of age treated with ODACTRA vs placebo included throat irritation/tickle (67.0% vs 20.8%), itching in the mouth (61.3% vs 14.1%), itching in the ear (51.7% vs 11.7%), and swelling of the uvula/back of the mouth (19.8% vs 2.4%).

All pregnancies have a risk of birth defect, loss, or other adverse outcomes. Available data on ODACTRA administered to pregnant women are insufficient to inform associated risks in pregnancy.

Before prescribing ODACTRA, please read the Boxed WARNING, full Prescribing Information, and Medication Guide, for additional Important Safety Information.
