Irritant rhinitis, or vasomotor rhinitis describes a group of other causes of rhinitis, with symptoms not caused by infection or allergy. Many people have recurrent or chronic nasal congestion, excess mucus production, itching, and other nasal symptoms similar to those of allergic rhinitis, but the disorder is not caused by allergy.

Some people are very sensitive to abrupt changes in weather or temperature. Skiers often develop a runny nose, but in some people any cold exposure may cause a runny nose. Others start sneezing when leaving a cold, airconditioned room. These agents are not allergens, do not induce formation of allergic antibodies, and do not produce positive skin test reactions.

In a sufficiently high concentration, many odors will cause nasal irritation in almost anyone. Some people are unusually sensitive to irritation and will have significant nasal symptoms even when exposed to low concentrations of irritants.
