Living with non-allergic rhinitis: what to know

Non-allergic rhinitis is inflammation or over-reactivity inside the nose without the typical allergic reaction to pollen, dust mites, or animal dander. The lining can react to smoke, perfume, cleaning fumes, traffic pollution, cold air, changes in temperature, or spicy food. Hormonal changes and some medicines can also contribute. Symptoms may include a blocked nose, watery discharge, sneezing, post-nasal drip, or reduced sense of smell. They can come and go, and a person may have more than one trigger.

Because the symptoms overlap, a clinician may review their pattern, examine the nose, and consider whether allergy, sinus disease, medication effects, or another cause fits better. Non-allergic rhinitis is different from allergic rhinitis, although both can occur in the same person.

Keep a brief symptom diary showing what you were exposed to, whether one or both nostrils were affected, and how long the episode lasted. This can reveal a connection with fragrance, air conditioning, cooking vapour, or a workplace environment. Avoid smoke and move away from strong fumes when possible. A well-fitting mask may reduce exposure to dust or irritants during unavoidable tasks.

Saline nasal spray or a saline rinse can wash away irritants and loosen mucus. Use clean equipment and water prepared according to the product instructions. A clinician or pharmacist may suggest a nasal steroid or another spray, depending on the dominant symptom. Decongestant nasal sprays should only be used for the short period stated on the label, because longer use can make blockage harder to control. Do not change a prescribed medicine without checking first.

Arrange a medical review if symptoms keep returning, disturb sleep, affect exercise or work, or do not improve with sensible trigger avoidance. Assessment is also useful when congestion lasts, your sense of smell stays reduced, or you are unsure whether the problem is allergic rhinitis, sinusitis, or a medicine effect.

Seek urgent care for trouble breathing, swelling of the lips or throat, severe facial or eye swelling, sudden vision changes, confusion, or a severe headache with fever and a stiff neck. Prompt assessment is appropriate for repeated nosebleeds, bloody discharge, or blockage that is persistent and mainly on one side.

You could ask: Which triggers best match my symptom pattern? Do I need allergy testing or an examination of my sinuses? Which nasal spray suits congestion, discharge, or post-nasal drip? How should I use it, and when should it be reviewed? Could any of my current medicines be contributing?
