Quick action is essential during a serious allergic reaction (anaphylaxis). Kind of like a fire drill, it's smart to occasionally review the instructions your doctor gave you and run through the steps you would take in an emergency.

Here are the top things to know if you're at risk for anaphylaxis:

1. If your doctor has prescribed for emergencies, make sure two doses are always with you: at school, at a party, on vacation — everywhere. Always have two in case one doesn't work or you need a second dose. Work with your school to decide where to store the epinephrine and how you'll get it quickly, if needed. Don't leave it in the car or anywhere else where it might get too hot or too cold — temperature can affect how well epinephrine works.
2. Know the signs of a serious reaction, such as trouble breathing or throat tightness, and be ready to act quickly. You also need to use epinephrine if you have two or more mild symptoms, such as hives plus vomiting or coughing plus belly pain. Follow the instructions your doctor gave you
3. Practice how to use the epinephrine so you don't forget. Are there caps to remove or twist? Is it an injector or a nasal spray? Which end delivers the medicine? Where on the body do you give it? How do you hold it? Ask for a demonstration at your doctor's office. Visit the manufacturer's website to get detailed instructions. Some manufacturers also may supply a trainer that has no epinephrine in it, so you can practice all the steps safely.
4. If you have a reaction that seems to be anaphylaxis, use the epinephrine right away. Have someone call 911 while you give yourself the epinephrine. If you are alone, call 911 right after using epinephrine to take you to the nearest emergency room. Sometimes people have a second wave of symptoms that need medical care. Take the used epinephrine device to the hospital with you.
5. Store the epinephrine according to the manufacturer's directions. Note the expiration date and get more before what you have expires.
