Common symptoms of an allergic reaction include:
- sneezing, an itchy, runny or blocked nose
- itchy, red, watering eyes
- wheezing, chest tightness, shortness of breath and a cough
- a raised, itchy, red rash
- swollen lips, tongue, eyes or face
- tummy pain, feeling sick, vomiting or diarrhoea
- dry, red and cracked skin

These symptoms may vary depending on what you’re allergic to and how you have come into contact with it.
For example, you may have a runny nose if exposed to pollen, develop a rash if you have a skin allergy, or feel sick if you eat something you’re allergic to.
See a doctor if you or your child might have had an allergic reaction to something, to determine whether the symptoms are caused by an allergy or another condition.
