Allergic rhinitis means allergies or hay fever. When you are exposed to particles in the air that you're allergic to, like pollen, dust, or cat dander, your immune system attacks the particles and causes symptoms such as sneezing and a runny nose.
You may have symptoms often during the year, or just at certain times.
