If you or someone you know has a
severe allergy, you might hear about epinephrine auto-injectors like the
EpiPen®.
Although these pens can be pricey,
it’s important to carry them with you if your doctor recommends it. They just
might save your life.
What is an epinephrine auto-injector?
Epinephrine auto-injectors such as
the EpiPen®
are used for the treatment of life-threatening allergic
reactions that can occur in response to an allergen, exercise, or an unknown
trigger. Epinephrine can reverse the symptoms of anaphylaxis,
a serious allergic reaction that can result in difficulty breathing, a sudden
drop in blood pressure, loss of consciousness, and even death. Prevention
is trigger avoidance. Epinephrine is first-line treatment.
How do epinephrine auto-injectors work?
These auto-injectors
contain epinephrine, otherwise known as adrenaline, which relaxes the
muscles in the lungs and opens up the airways to improve breathing. It also increases
heart rate and blood pressure and reduces swelling that may occur around the
face and lips. The medication may wear off after 10 or 20 minutes and symptoms can
come back, so be sure to call 911 as soon as epinephrine is used.
How do you use an epinephrine
pen?
Different brands of epinephrine
auto-injectors operate differently, so read the directions before using to be
sure you use it right. Generally, when someone begins to show the first signs
of a sudden allergic reaction, remove the cap on the device and push the needle
firmly against the side of their outer thigh to release the medication. Epinephrine
enters the blood stream immediately, kicking in within 30 seconds. Avoid
injecting this medication into your hands, feet, buttocks, or areas of your
body other than the thigh.
What are epinephrine side effects?
After receiving an injection of
epinephrine, you could feel a pounding heartbeat, nervousness, sweating,
nausea, dizziness, shakiness or pale skin. If any of these effects last or get
worse, or you experience other side effects, check with your doctor right away.
Before using epinephrine, tell your
doctor or pharmacist if you have any other types of allergies or medical
problems.
