When collecting your EpiPen® or EpiPen® Jr Auto-Injector prescription, your pharmacist may try to switch it, or talk to you about switching to Anapen®.1

EpiPen® Auto-Injectors and Anapen® are not the same:2-4

EpiPen® takes just 2 steps to use.2,3

Anapen® takes more steps.4

EpiPen® has a Never-See-Needle.™2,3

Anapen®’s needle is exposed after use.4

  • Switching means retraining: You, your family, friends and caregivers must retrain to use a different device correctly if you have an anaphylactic attack2-4
  • Switching means a different ASCIA Action Plan: You will also need to get a new ASCIA Action Plan, specific to Anapen®5

Remember, you don’t have to change. It’s your choice6
Be specific and tell your GP and pharmacist that you want your EpiPen® Auto-Injector prescription.
