EpiPen (epinephrine) is a solution injected under the skin or into the thigh muscle to treat severe allergic reactions. It usually comes in a prefilled syringe as part of a so-called auto-injector.

What is Anaphylaxis?

Anaphylaxis is a severe, life-threatening allergic reaction that can take place suddenly, making it difficult to reach an emergency room in time. This is why EpiPen, used by the patient or a family member, can be life-saving. Contrary to popular belief, an anaphylactic reaction is not limited to the skin or the throat but can involve many organ systems.

Signs and symptoms of anaphylactic reactions are:

  • Hives (reddened areas)
  • Itching
  • Numb or swollen lips
  • Pale or flushed skin
  • Low blood pressure (hypotension)
  • Difficulty breathing, wheezing
  • Swollen tongue or throat
  • Weak, rapid pulse
  • Nausea and vomiting
  • Diarrhea
  • Dizziness
  • Loss of consciousness

Causes of Anaphylaxis

Causes of anaphylaxis can be unique to any individual, but some common allergens are:

  • Bee stings
  • Yellowjackets
  • Hornets
  • Wasps
  • Fire ants
  • Peanuts
  • Shellfish
  • Fish
  • Eggs
  • Milk
  • Tree nuts
  • Latex
  • Penicillin
  • Radiocontrast dyes
  • Exercise (rare)

When to Use the EpiPen?

If you have a history of anaphylaxis and you know you have been exposed to something you are severely allergic to and are showing early signs, then use the EpiPen immediately to avoid progression to a severe anaphylactic reaction.

Anaphylaxis can be deadly if not treated promptly. 

However, it’s important to note that the EpiPen is a temporary solution, not a substitute for professional medical care. After using the EpiPen, seeking immediate medical attention is crucial to ensure proper follow-up and prevent potential complications.

Do EpiPens Expire?

EpiPens generally expire after about two years and should be replaced if not used within that time period.

EpiPens’ expiration dates are generally about two years from the date of manufacture. However, this time frame may be even less if the EpiPen has been exposed to heat—for example, by leaving it in a car during a hot day. 

According to one study, the EpiPen becomes significantly less effective when left in the car on a hot day, even just once. Therefore, it is crucial to keep the EpiPen with you in a bag or purse at all times and not leave it exposed to heat or the sun.

Remember, an expired or ineffective EpiPen may not provide the necessary relief during an anaphylactic reaction.
