  • Avoid triggers such as foods and medications that have caused an allergic reaction, even a mild one, in the past. This includes detailed questioning about ingredients when eating away from home. Ingredient labels should also be carefully examined.
  • If you have a child who is allergic to certain foods, introduce one new food at a time so you can recognize an allergic reaction.
  • A medical ID tag should be worn by people who know that they have serious allergic reactions.
  • If you have a history of a serious allergic reactions, carry emergency medications (such as diphenihydramine and injectible epinephrine or a bee sting kit) according to your health care providers instructions.
  • Do not use your injectible epinephrine on anyone else. They may have a condition (such as a heart problem) that could be affected by this drug.
