If you have seasonal allergies in addition to house dust mite allergy, ODACTRA may still help. If you are allergic to house dust mites and have symptoms year-round, house dust mites may be considered an "anchor" —something that makes your overall allergy symptoms worse all year.
If house dust mites are an “anchor” for you, treating your house dust mite allergy may help you feel better overall. Some health care providers think this is because all of the allergens you are allergic to add up to cause your allergy symptoms. This means that, during allergy seasons, your house dust mite allergy may be making you feel worse overall.
What is ODACTRA?
ODACTRA is a prescription medicine used for sublingual (under the tongue) immunotherapy to treat house dust mite allergies that can cause sneezing, runny or itchy nose, stuffy or congested nose, or itchy and watery eyes. ODACTRA may be prescribed for persons 18 through 65 years of age who are allergic to house dust mites. ODACTRA is NOT a medication that gives immediate relief for symptoms of house dust mite allergy.
