Allergy Defence 500mg Care Allergy Defence is a unique nasal powder spray that is antihistamine & steroid free. It reinforces the body's own defences by forming a physical shield against airborne allergens, making treating hayfever & other allergies a walk in the park. How it works Care Allergy Defence uses ' Nasaleze' technology to stop the cause rather than just treating the symptoms. It is a powder that reacts with moisture in the nose to become an invisible, but effective, barrier that blocks airborne allergens like dust, pollen & germs from getting into the body. This stops the body's natural defence system from releasing histamine so symptoms like runny nose & itchy, watery eyes are avoided. Because it has a physical action & is not absorbed by the body, Care Allergy Defence does not interact with any other medicines & is safe for pregnant & breast-feeding women to use. It is suitable for children from 18 months (under supervision). Easy to use People testing Care Allergy Defence have found it simple & comfortable to use with no powder residue & no feeling of it being present in the nose. When the bottle is squeezed, air forces powder up the hollow tube. The air & powder travel up the hollow delivery tube to the nozzle. The nozzle delivers a fine mist of powder Instructions Gently blow your nose, then shake the bottle, breathe out & place a finger over one nostril to close it. Place the Care Allergy Defence bottle nozzle in the other nostril & slowly but firmly push the sides of the bottle together to deliver one 'puff' of powder while inhaling gently. Wait 2 seconds & inhale gently to help the powder penetrate the nasal passages. Then repeat for the other nostril.
