Epi-pen

Epi-pen is the brand name of the most common type of autoinjector of epinephrine (i.e. adrenaline). Because they can be self-administered and are very fast-acting, Epi-pens are commonly carried by persons with severe allergies and a risk of anaphylactic shock. In the US and the United Kingdom, Epi-pens are regulated medical devices and require a prescription.

The standard dosage of Epinephrine which is supplied by an Epi-Pen is 0.3ml of 1 in 1000 Parts (.3mg)

The Pen usually has a shelf life of about 12 months, or until the contents contain a Precipitate or they discolor, whichever comes earlier. Once this occurs, the Epi-pen should be discarded if unused by returning it to your local drugstore, pharmacy or hospital for safe disposal.

Despite being trademarked, common usage of the word epi-pen is drifting toward the generic context of any autoinjector.

The carrying tube that the pen comes in is easily broken; however, several companies sell durable replacement carrying tubes.

Usage notes

• Follow the emergency instructions in the kit.
• Do not remove the locking cap until ready to use the injector.
• The thigh is the recommended injection site.
• Hold in place for 10-15 seconds to allow time for the auto-injection to complete.
• Seek immediate medical attention regardless of the use of the Epi-pen.
