Find answers for nasal symptoms triggered by irritants, weather, or other factors.
What is Non-Allergic Rhinitis?
Non-allergic rhinitis can cause symptoms similar to allergic rhinitis, including congestion, runny nose, and postnasal drainage, but allergy testing is negative. Unlike allergic rhinitis, it is not caused by an immune response. It is common and can be equally disruptive to daily life.
Common Triggers
Temperature Changes
Cold air or air conditioning.
Strong Odors
Perfumes, cleaning products, or smoke.
Alcohol
Alcoholic beverages can trigger symptoms.
Spicy Foods
Eating spicy foods can cause gustatory rhinitis.
Hormonal Changes
Pregnancy or thyroid disease.
Certain Medications
Including overuse of decongestant nasal sprays, known as rhinitis medicamentosa.
Rebound Congestion From Nasal Sprays
Frequent use of over the counter decongestant sprays, such as oxymetazoline or phenylephrine, can cause rebound congestion called rhinitis medicamentosa. The nose can become reliant on the spray to remain open, with severe congestion occurring when it is stopped. Treatment involves gradually stopping the decongestant spray, often with the use of nasal steroid sprays.
Managing Non Allergic Rhinitis
Treatment centers on avoiding triggers and controlling symptoms. Nasal steroid sprays and nasal antihistamine sprays can help many patients. Ipratropium nasal spray can be particularly effective for a runny nose. Identifying and addressing medications that contribute to symptoms is also important.
