What are allergies?
“Allergies” is a general term that refers to a reaction the body has to allergens. Allergens are substances that are generally not harmful to the body.
Allergic rhinitis refers to inflammation in the nose (rhinitis) that occurs when you are exposed to a substance you are allergic to. Allergic rhinitis is sometimes called “hay fever” or “seasonal allergies,” although it can be caused by nonseasonal substances as well.
The term “allergic rhinitis” does not refer to all kinds of allergies you may have. For example, food allergies and allergies to medications do not typically cause allergic rhinitis.
Treatment is only available through Roman for allergic rhinitis, if appropriate. Treatment is not available for food allergies or medication allergies.
