Non-allergic rhinitis

Also called Vasomotor rhinitis

Non-allergic rhinitis is when the inside of the nose is swollen, causing a blocked or runny nose and sneezing, but it is not caused by an allergy. It can be triggered by changes in temperature or humidity, smoke, strong smells, spicy food, alcohol, hormone changes or some medicines, including overuse of decongestant sprays.

What it is

Avoiding triggers and rinsing the nose with salt water often help.

Steroid nasal sprays, antihistamine sprays or sprays that dry a runny nose may be used.

Common signs

  • Blocked nose
  • Runny nose
  • Sneezing
  • Mucus running down the back of the throat
  • No itchy eyes

How it is usually diagnosed

  • Questions about symptoms and triggers
  • Allergy tests to rule out allergic rhinitis

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Allergy test results
  • Treatments tried
  • ENT letters, if seen

Questions to ask your doctor

  • Could my nasal spray be making it worse?
  • Which treatment should I try?
  • Do I need allergy tests?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Blocked nose on one side only with bleeding, or swelling around the eye: get it checked soon
