Allergy symptoms are nothing to "sneeze" at. Allergic rhinitis affects between 10 and 30% of people around the world - men, women and children. Allergic rhinitis refers to irritated, inflamed nasal passages from exposure to something you're allergic to. Chances are you're already familiar with the symptoms of seasonal allergies - runny nose, nasal stuffiness, itchy eyes, sneezing and eye puffiness. Needless to say these symptoms don't help you look or feel your best. For years Allegra has been helping allergy sufferers get relief from hard-to-manage allergy symptoms.
