The following precautions may help prevent hives and angioedema:

  • Avoid known triggers. These may include certain foods or food additives, alcohol, medications, or situations such as temperature extremes, tight clothing or emotional stress.
  • Keep a diary. Track all of your activities, when and where hives occur, and what you eat. This may help you and your doctor identify triggers.
  • Avoid medications that may trigger hives. These include aspirin, ibuprofen (Advil, Motrin, others), naproxen sodium (Aleve, Anaprox, others), codeine or any other medication that you've noticed can trigger your hives.
