What is an adrenaline autoinjector?
++

An adrenaline autoinjector is an emergency device that can inject life-saving adrenaline promptly in emergency situations. It is used to treat severe allergic reactions, known as anaphylaxis, which may follow an insect bite or eating a certain food. There are two currently available commercial preparations—the Anapen and the EpiPen—each has a different method of injection into the outer mid thigh, and both come in adult and child (Junior) versions. Specific training of the carer and patient is required for each device. School-age children usually need the full-strength injector.

What is an Anaphylaxis Action Plan?

If you have an autoinjector, you must have an Anaphylaxis Action Plan signed by your doctor.

The four step use of the autoinjector (pen)
++
Step 1
++

  • Remove the pen from its container.

  • Then remove the safety cap from the end of the pen (pull it—don’t twist).

  • Ensure that your thumb is closest to the cap end and not over the sharp end of the pen.

++
Step 2
++

  • Hold the pen tightly in the palm of your hand with the needle tip down.

  • Place the needle tip gently against the middle of the outer thigh, in the ‘fleshiest’ part of the muscle (with or without clothing). It should be perpendicular (at a right angle of 90°) to the thigh.

++
Step 3

  • Push down hard against the thigh until you hear or feel a ‘click’ (in the case of the EpiPen) or for the Anapen, press the red button until it clicks.

  • Hold in place for 10 seconds.

++
Step 4
++

  • Remove the pen from the thigh.

  • Check the needle tip.

  • Place it back in its plastic container with the needle pointing down.

  • Be careful not to touch the needle.

  • Massage the injection site for 10 to 20 seconds.

  • Apply firm pressure with a clean cloth.

  • Record the time it was given.

  • Call an ambulance.
