Allergies are a common immune system response to things that are usually harmless. They can cause mild to severe symptoms, and can in some cases be life-threatening.

If you or someone around you is having a severe allergic reaction, phone 999 immediately to get urgent medical help.

You might have allergies if you have:

Itchy or watery eyes, nose, or throat
Frequent sneezing fits
Skin rashes or hives
  • Pollen from trees, grasses, or weeds
  • Dust mites
  • Pet dander
  • Mould spores
  • Certain foods, such as nuts, shellfish, or dairy
  • Runny or stuffy nose
  • Sneezing fits
  • Coughing or wheezing
  • Swelling of the face, lips, tongue, or throat
  • Avoid known triggers whenever possible
  • Keep indoor spaces clean and well-ventilated
  • Use air purifiers or allergy-proof bedding
  • Take over-the-counter antihistamines or decongestants
  • In the case of a severe allergic reaction, use your epinephrine auto-injector (EpiPen)
