To lower your likelihood of experiencing hives or angioedema, take the following precautions:

  • Avoid known triggers. These may include certain foods or medications or situations such as temperature extremes that have triggered hives or angioedema in the past.
  • Keep a diary. If you suspect food is causing the problem but aren't sure which food is the trigger, keep a food and symptom diary.
