Allergic rhinitis is sometimes called "hay fever" or "seasonal allergies," although it can be caused by nonseasonal substances as well. Allergic rhinitis refers to inflammation in the nose (rhinitis) that occurs when you are exposed to a substance you are allergic to. 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.

There are many different allergens that affect the body. These include foods, plants, animals, metals, chemicals, medications, and more. Some allergens are known as airborne allergens because they are present in the air. The most common airborne allergens include tree pollens, grass pollens, weed pollens, pet dander, and molds. Dust mites and cockroach allergens are also common and may be airborne, however they settle more quickly than the other airborne allergens.

Dapper only offers treatment for allergic rhinitis, which is caused by airborne allergens. However, there are many other common allergens you may have. The most common food allergens are fish, shellfish, peanuts, tree nuts, eggs, wheat, soy, and milk. These allergens always need to be labeled on food if they are present. Other allergens you may have heard of include:

1. Insect venom (e.g. getting stung by a bee)
2. Nickel (e.g. getting a rash after wearing certain jewelry)
3. Latex (e.g. getting a rash when coming into contact with latex)
4. Medications (e.g. getting hives after taking penicillin)
