Sudden allergic swelling or hives

What this means

An allergic reaction can cause raised itchy welts (hives) or sudden swelling. Most settle, but swelling of the face, lips, tongue or throat with breathing difficulty is a life threatening emergency.

Safe to do at home

  • Stop and avoid the suspected trigger, such as a food or medicine
  • Apply a cool compress to itchy skin
  • Keep calm and watch closely for any breathing or throat symptoms

Please do not do this alone

  • Do not take a medicine again that you suspect caused the reaction
  • Do not wait if the lips, tongue or throat start to swell
  • Do not take other people's allergy injections

Book a consultation if

  • You get repeated hives or swelling
  • Reactions follow a clear trigger you need help to identify
  • Mild reactions are becoming more frequent

Get help immediately if

  • Swelling of the face, lips, tongue or throat
  • Difficulty breathing, wheezing or a tight throat
  • Dizziness, fainting or a widespread reaction after a food, sting or medicine
