Health condition
Non-allergic rhinitis
Non-allergic rhinitis produces the running, blocking and sneezing of hay fever without the allergy - triggered by temperature shifts, smells, food and medication - and it responds to a different treatment emphasis.

-
Symptoms mirror allergic rhinitis but allergy tests are negative

Ipratropium spray specifically controls profuse watery running
Understanding the condition
What it is and what happens next.
What causes it, how it is diagnosed, and the treatment routes available in the UK.
What it is and how it feels
The non-allergic rhinitis nose is hyperreactive rather than allergic: its nerves and glands over-respond to physical and chemical stimuli - walking into cold air, fragrance aisles, a glass of wine - producing congestion, watery discharge and post-nasal drip year-round. Variants include vasomotor rhinitis, rhinitis of ageing with its clear drip, hormonal rhinitis in pregnancy, and drug-induced forms from decongestant overuse and some blood pressure medication.
Diagnosis and treatment routes
Diagnosis combines the trigger pattern with negative allergy testing and examination to exclude polyps and structural disease. Treatment leans on intranasal azelastine - notably effective in non-allergic disease - combined with a steroid spray, saline rinses to wash irritants, and ipratropium before triggers for watery rhinorrhoea; identifying and adjusting culprit medication, and weaning decongestant sprays, resolves the iatrogenic cases. In many parts of the UK, routine NHS referrals for this kind of problem currently take 20-45+ weeks, whereas an initial appointment with a private consultant is typically available within around two weeks.
Seeing a specialist
Who to see, and how quickly you can be seen.

Frequently asked
Common questions about Non-allergic rhinitis.
Quick, plain-English answers to what people ask us most.
-
What is non-allergic rhinitis?
Non-allergic rhinitis produces the runny nose, blocked nose and sneezing of hay fever without an allergic cause, triggered instead by temperature shifts, strong smells, certain foods, or other non-allergic irritants.
-
What causes non-allergic rhinitis?
Triggers include changes in temperature or humidity, strong odours, alcohol, certain medications, hormonal changes, and spicy food, reflecting an overly sensitive nasal lining rather than a true allergic reaction.
-
How is non-allergic rhinitis diagnosed?
Diagnosis is largely made by excluding allergy through skin prick or blood testing, alongside a history that shows a pattern of triggers not typical of allergic rhinitis.
-
Is non-allergic rhinitis serious?
It is not dangerous but can be persistent and bothersome, and identifying specific triggers can help significantly reduce symptoms even without a cure.
-
How is non-allergic rhinitis treated?
Treatment includes avoiding identified triggers, nasal steroid sprays, and other nasal treatments such as antihistamine nasal sprays, chosen based on the specific symptom pattern.
-
Non-allergic rhinitis vs hay fever - what's the difference?
Hay fever (allergic rhinitis) is triggered by specific allergens like pollen and confirmed by positive allergy testing, while non-allergic rhinitis causes similar symptoms without allergy, triggered instead by non-allergic irritants such as temperature change or strong smells.
-
When should I see a specialist about non-allergic rhinitis?
See your GP if nasal symptoms are persistent and not responding to standard treatment. A private ENT surgeon can typically be seen within about two weeks for further assessment.
