What is an EpiPen®
An EpiPen® is a self-injectable device filled with Epinephrine. Epinephrine is adrenaline. Adrenaline is a hormone produced by your adrenal glands. As a drug, it is used to treat anaphylaxis and is most effective when used immediately following ingestion of the allergen.

There are two types of EpiPen®'s:
EpiPen® Jr. for those who weigh between 33 and 66 lbs**

EpiPen® for those who weigh over 66 lbs.

(**these figures vary, some sources state that the EpiPen® Jr is good up to 33lbs, my information was received directly from the manufacturer EpiPen dosing)

Each EpiPen® self-injector is good for one time usage only. It is advisable to carry more than one EpiPen® with you at all times.

The reasons to carry more than one are:

  • Periodically an EpiPen® may misfire.
  • When used, each EpiPen® lasts between 10 and 20 minutes; therefore, if you are more that 10 minutes from emergency medical care, you will need to administer more than one dose prior to obtaining medical care.

How to Use Your EpiPen®:
(**Note: up to 90% of the epinephrine liquid stays in the auto-injector once it has been used)

1. Pull off gray safety cap to activate

2. Hold EpiPen® in the middle – do not touch either end with your hand

3. Place the black tip firmly against the outer middle part of the thigh only and push in until you feel it click – remember: you can use EpiPen® over clothing in an emergency

4. Hold in place for at least 10-15 seconds then remove it

5. Call 911

6. Rub the site of the injection gently for at least 10 seconds.

It is important to note that every EpiPen® expires. Always be sure to replace your EpiPen® immediately upon it’s expiration. An excellent tip is to phone ahead to the pharmacy you purchase from and request an EpiPen® with the maximum time until expiration. A typical expiration range is between 12 and 16 months from time of purchase.

**Apparently most pharmacies receive their yearly EpiPen® shipment in March. I was recently informed that this is the case - however, every pharmacy is different - but if you want maximum expiration dates - it would appear March would be a good time - BE sure to request the newest EpiPen® or you may receive old stock.**

Be careful not to expose your EpiPen® to harsh conditions such as full sun, heat or extreme cold. The best temperature range to keep your EpiPen® in is between 15-30°C. See your package insert from your EpiPen® for full-explanation of how to store your EpiPen® and to learn proper usage. Note that if the liquid in the EpiPen® is discolored, it should be immediately replaced.
