Anaphylactic Reaction: Care Instructions

Overview

A severe allergic reaction can affect your whole body. Doctors call it an anaphylactic reaction. Your immune system may have reacted to food or medicine. Or maybe you had an insect bite or sting. This kind of reaction can happen the first time you come into contact with a substance. Or it may take many times before a substance causes a problem.

You need to get emergency help right away every time you have an anaphylactic reaction.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

• If your doctor has prescribed medicine, such as an antihistamine, take it exactly as directed. Call your doctor if you think you are having a problem with your medicine.
• Your doctor may prescribe an epinephrine medicine, such as an epinephrine shot or nasal spray, to carry with you in case you have a severe reaction. Learn how to give yourself the medicine. Keep it with you at all times.
• Learn all you can about your allergies. You may be able to avoid a severe response when you do or don't do certain things. For instance, you can check food or drug labels for contents that might cause a reaction.
• Wear medical alert jewelry that lists your allergies. You can buy this at most drugstores.
• Teach people around you about your allergies. Tell them what you need to avoid. Teach them what to do if you have a reaction.
• Before you take any medicine, tell your doctor if you have had a bad response to any medicines in the past.

When should you call for help?

Watch closely for changes in your health, and be sure to contact your doctor if:

• You have new or worse symptoms.
• Your symptoms are interfering with your daily activities, sleep, school, or work.
• You have questions about medicines or allergy testing.
• You do not get better as expected.
