By Mayo Clinic staffNonallergic rhinitis involves chronic sneezing or having a congested, drippy nose with no apparent cause. The symptoms of nonallergic rhinitis are similar to those of hay fever (allergic rhinitis), but there's no allergic reaction involved. Nonallergic rhinitis can affect children and adults, but is more common after age 20.
Although nonallergic rhinitis is more annoying than harmful, it can make you miserable. Triggers of nonallergic rhinitis symptoms vary from person to person and can include certain odors or irritants in the air, changes in the weather, some medications, certain foods, and chronic health conditions. A diagnosis of nonallergic rhinitis is made after an allergy is ruled out. This may require allergy skin or blood tests.
