Things you can do if you have non-allergic rhinitis

You can often treat it without seeing a GP.

Try to avoid the things that trigger your symptoms, if you can.

A pharmacist can advise you about medicines that can help, such as:

You can buy nasal sprays without a prescription, but they should not be used for more than a week. Using them for longer than this can make the problem worse.

How to clean your nose with a homemade salt water solution
  1. Boil a pint of water, then leave it to cool.
  2. Mix 1 teaspoon of salt and 1 teaspoon of bicarbonate of soda into the water.
  3. Wash your hands.
  4. Stand over a sink, cup the palm of 1 hand and pour a small amount of the solution into it.
  5. Sniff the water into 1 nostril at a time. Breathe through your mouth and allow the water to pour back into the sink. Try not to let the water go down the back of your throat.
  6. Repeat the first 5 steps up to 3 times a day (making a new solution each time) until your nose feels more comfortable.

If you have a high temperature or you do not feel well enough to do your normal activities, try to stay at home and avoid contact with other people until you feel better.

Treatments for non-allergic rhinitis from a GP

Non-allergic rhinitis often gets better on its own without any treatment.

If needed, a GP may prescribe stronger medicine, such as prescription nasal sprays.

They may also change any medicine you're taking if they think it may be causing your symptoms.

You may be referred to a specialist for further tests and treatment if it's not clear what's causing your symptoms or they're severe.
