Sterimar Nasal Spray on Prescription

Sterimar Nasal Spray will not routinely be available on NHS prescription

Following national and local NHS guidance, Sterimar nasal spray and similar saline nasal sprays will no longer be routinely prescribed in primary care. This is because guidance recommends that a salt solution can be easily made up to rinse the nose or if preferred, higher cost products like Sterimar can be purchased from pharmacies and supermarkets. Guidance for making up the salt solution is provided below.

We understand that this may be an adjustment for you. Please be reassured that the homemade salt solution is safe and effective and advised by out Ear Nose and Throat Team.

If you have ongoing symptoms or concerns about your nasal health, please contact the practice so we can review your treatment and ensure you have the most appropriate care.

Thank you for your understanding and for helping us use NHS resources responsibly.

How to make and use a salt water rinse for your nose

The benefits

When you rinse your nose with this salt water and bicarbonate of soda mixture, it washes irritants from your nose and moisturises it. Salty water pulls fluid out of the swollen linings of your nose letting you breathe more easily and opening up the sinus passages. It also helps your nose work better and clear mucous more quickly.

There are no nasal rinse products available on prescription but you can purchase a sinus rinse pack at most chemists. This instruction sheet describes a recipe you can make up at home. Alternatively you can buy a salt water aerosol spray at the chemists.

 

The recipe

Clean and rinse a 500ml bottle or other container and fill it with water (you don’t have to boil the water first).

To 500mls of water add one heaped teaspoonful of salt and half a teaspoon of bicarbonate of soda.

Stir the mixture or shake the bottle before each use.

Store at room temperature. After a week you should throw away any mixture you have left and make some more. If the mixture seems to strong try using half a teaspoon of salt per pint of water.

 

How to rinse out your nose

1.       You should rinse out your nose two or three times daily.

2.       Pour some salt-water mixture into a clean bowl. If it is cold you can warm the mixture a little, e.g. in a microwave. Check that it is not too hot before using it.

3.       Stand over a sink or in the shower and squirt up gently to each side of your nose – about 10mls to each nostril. Aim slightly towards each eyeball.

4.       You may spit some of the salt water out of your mouth, but it does not matter if you swallow some.

5.       You may notice a slight burning feeling at the back of your nose in a day or two. Blow your nose when you are finished.
