Drug Allergy

ExitCare ImageA drug allergy means you have a strange reaction to a medicine. You may have puffiness (swelling), itching, red rashes, and hives. Some allergic reactions can be life-threatening.


If you do not know what caused your reaction:

  • Write down medicines you use.

  • Write down any problems you have after using medicine.

  • Avoid things that cause a reaction.

  • You can see an allergy doctor to be tested for allergies.

If you have hives or a rash:

  • Take medicine as told by your doctor.

  • Place cold cloths on your skin.

  • Do not take hot baths or hot showers. Take baths in cool water.

If you are severely allergic:

  • Wear a medical bracelet or necklace that lists your allergy.

  • Carry your allergy kit or medicine shot to treat severe allergic reactions with you. These can save your life.

  • Do not drive until medicine from your shot has worn off, unless your doctor says it is okay.


  • Your mouth is puffy, or you have trouble breathing.

  • You have a tight feeling in your chest or throat.

  • You have hives, puffiness, or itching all over your body.

  • You throw up (vomit) or have watery poop (diarrhea).

  • You feel dizzy or pass out (faint).

  • You think you are having a reaction. Problems often start within 30 minutes after taking a medicine.

  • You are getting worse, not better.

  • You have new problems.

  • Your problems go away and then come back.

This is an emergency. Use your medicine shot or allergy kit as told. Call your local emergency services (911 in U.S.) after the shot. Even if you feel better after the shot, you need to go to the hospital. You may need more medicine to control a severe reaction.
