What Is an EpiPen and What Is It Used For?
is the brand name of a device that delivers the drug epinephrine, which is a life-saving medication used when someone is experiencing a severe allergic reaction, known as anaphylaxis.
EpiPen is an auto-injectable device and the generic term is injectable epinephrine. This #medication
acts on the whole body to shut down the allergic response. For example, it constricts the blood vessels, leading to increase #bloodpressure
, and decrease swelling; it relaxes the #muscle
around the #airway
, causing the #lungs
to open up; and lastly, it prevents the release of more allergic chemicals, which stops the progression of the allergic response.
Epinephrine is the only medication that works on the entire body, #multi
-system, multi-organ for #anaphylaxis
, which is why it is the drug of choice.
How do you know if you need injectable #epinephrine
First and foremost, if you suspect you have had an allergic reaction to a #food
or insect sting, you should see a board-certified #allergist
to evaluate your reaction/symptoms. The allergist will obtain pertinent medical history, perform a physical exam, and recommend diagnostic testing if indicated.
If you already have a diagnosis of food #allergy
, it is important to see your allergist regularly for possible re-testing and an oral challenge to determine if you have outgrown some of your allergic triggers. In some cases a #prescription
for injectable epinephrine may no longer be medically necessary.
