Care allergy defence

How does it work?

Care allergy defence nasal spray is a medical device that contains a natural cellulose powder as its main ingredient.

When this spray is used in the nose, the powder reacts with moisture on the lining of the nose to form a colourless fine gel coating. This gel acts as a filter, trapping airborne allergens such as pollen and dust, and stopping them from coming into contact with the lining of the nose. This prevents the allergens from causing the allergic reactions in the nose that produce hayfever-type symptoms.

Care allergy defence spray should be used as often as needed, but at least three times a day. Using the spray regularly maintains a good barrier on the lining of the nose, which will help to prevent the symptoms of hayfever or other nasal allergies from developing.

You can also use the spray as a preventative measure before entering an environment that you know might trigger your allergy, for example before going into the garden, mowing the lawn, dusting, or visiting a house where there are pets.

You should use the spray again after every time you blow your nose.

What is it used for?

  • To help prevent the symptoms of allergies that are caused by airborne allergens, for example hayfever, dust mite allergy or pet allergies.


  • This spray is for nasal use only. It should not be taken by mouth. Avoid getting the spray in your eyes.
  • This spray should not be used together with any other nasal sprays because this can make it less effective.
  • Before using the spray for the first time, squeeze down the collar several times until an even spray emerges.
  • Any remaining nasal spray should be discarded six months after the spray is first opened. This is because it could be contaminated with dirt or germs. Write the date of opening on the bottle so you know when to throw it away. Dispose of product carefully, preferably by returning it to your pharmacy.
