How can I prevent hives (urticaria) and swelling (angioedema)?

Allergy tests can help your healthcare provider figure out which substances bring on hives and swelling. Once you know your triggers, you can avoid them. You may want to:

  • Cut certain foods or liquids out of your diet.
  • Reduce exposure to airborne allergens.
  • Switch to detergents and soaps without scents or dyes.
  • Avoid extreme changes in temperature.
  • Relax and take a break when you’re stressed or overworked.
  • Wear loose-fitting, lightweight clothing.
