If you have had a severe allergic
reaction in the past, you know how frightening it can be. Symptoms of breathing
difficulty, itching, and swelling can come on quickly and become
life-threatening. Giving yourself an epinephrine shot can slow down or stop an
allergic reaction. That's why it is important to have an allergy kit containing
an epinephrine shot with you at all times and to know the right way to use it:
It could save your life someday.
There are some
important things to think about before you give the shot:
The shot does not replace the need to be seen
by a doctor. After giving yourself a shot, seek emergency care. Symptoms of a
severe allergic reaction can return or get worse after an epinephrine
shot.
An epinephrine shot should only be injected into the side of
the thigh. Do not give the shot into a buttock or a
vein.
Learn the signs that indicate a severe allergic reaction. If
you feel them coming on, act quickly.
It is also important to:
Keep an allergy kit with you at all times. Many
people keep one at home and one at work or school.
Keep two
epinephrine shots in each kit in case a second shot is
needed.
Giving yourself a shot does not replace the
need to be seen by a doctor. After giving the shot, seek emergency medical
care. Symptoms of a severe allergic reaction can return or get worse after an
epinephrine shot.

An epinephrine
shot can slow down or stop your allergic reaction. Epinephrine prevents your
body from releasing the chemicals that cause an allergic reaction. Epinephrine
relieves wheezing, breathing difficulties, and itching from
hives. It helps keep blood pressure within a normal
range and also reduces swelling that can occur in your hands, feet, eyelids,
tongue, and throat.
If you have had a serious allergic reaction in
the past, your risk of having another is high. But people react differently
when they are exposed to the
allergen that causes their allergic reaction. It is
important to get clear instructions from your doctor on when you should give
yourself an epinephrine shot.
An epinephrine shot comes as an
automatic injector that is prefilled with one shot of epinephrine. It is made
to be quick and simple to use.
Take care of your epinephrine
shot:
To protect it from light, keep the epinephrine
shot in the tube provided until you are ready to use it.
Store
epinephrine shot at room temperature—15
°C (59
°F) to
30
°C (86
°F). Do not
refrigerate.
Check the expiration dates of the medicines in the
allergy kit, and replace them as needed.
Check the medicine in the epinephrine shot. It should be clear.
If the solution is pinkish brown or has solid particles in it, the epinephrine
shot should be replaced.
Test Your Knowledge
I should keep my allergy kit in my car so it is always
handy.
To work properly, epinephrine needs to be kept
at room temperature. A car can get too hot. A better idea would be to keep one
kit in your purse, briefcase, or backpack; one at home; and one at work or
school.

Grasp the epinephrine shot injector in one
fist with the black tip pointing down. Do not touch the black tip.
With the other hand, pull off the gray cap.
Hold the
black tip close to your outer thigh. Swing and jab the black tip into your
outer thigh (through clothing if necessary). The injector should be at a
90-degree angle to your thigh.
Keep the injector in your outer
thigh while you slowly count to 5.
Remove the injector and rub the
area where the medicine entered your skin.
Look at the black tip:
If the needle is showing, you received the dose. If not, you need to repeat
steps 3 through 5.
Note:
It is normal for most of the
liquid to be left in the injector. Do not try to inject the remaining liquid.
After the shot, press the needle against a hard surface to bend
the needle back. Put the injector back in its case, needle first. Do not put
the gray activation cap back on the injector.
Take the
antihistamine tablet in your allergy kit.
You should feel the effects of the medicine almost right
away. These will include a rapid heartbeat and nervousness as well as improved
breathing. The benefits of the shot usually last 10 to 20 minutes.
In some severe cases, you may need to give a second shot. Your doctor
will explain when a second shot is needed. Make sure you understand, and ask
questions if you are not sure. Too much epinephrine can cause serious side
effects, such as difficulty breathing.
Test Your Knowledge
I don't like the idea of giving myself a shot. If I
have an allergic reaction, I can just go to the hospital.
You have been prescribed an allergy kit because
you are at risk for a dangerous allergic reaction. Symptoms can come on within
seconds and quickly become life-threatening. If you have a reaction, you cannot
wait until you get to a hospital to be treated. You must give yourself the shot
right away. Luckily, giving the shot is easy.

If you have any questions
about giving an epinephrine shot or about when to give a second shot, discuss
them with your doctor. It is important to know how to administer an epinephrine
shot before you need it.
