Non-allergic rhinitis

Last Updated: July 3, 2026

Key Points

Nasal irritation, not allergies
Blocked or runny nose, sneezing, sore throat
Triggered by weather, exercise, fumes, hormones
Often treatable with pharmacy medicines

Overview

Non-allergic rhinitis occurs when the lining inside your nose gets irritated, leading to symptoms similar to a common cold or allergies. Unlike allergic rhinitis, this condition is not triggered by allergens like pollen or dust mites. It's simply an inflammation or irritation of the nasal passages. Various factors can cause this irritation, including changes in weather, exercise, exposure to irritants like smoke or strong smells, certain foods or alcohol, hormonal shifts, and some medications. Underlying health conditions, such as an underactive thyroid, can also contribute. While not harmful, non-allergic rhinitis can be bothersome. Management typically involves identifying and avoiding triggers, along with using over-the-counter or prescription nasal sprays and other medicines to relieve symptoms.
