  • difficulty talking
  • collapse
  • loss of consciousness

First aid

How do I help someone suffering anaphylaxis?

How do I use an adrenaline injection pen (for example an Epipen or Anapen)?

EpipenAn Epipen or Anapen is an automatic adrenaline injector for the emergency treatment of anaphylaxis. Medical training isn't needed to use one.

Watch this short video on how to use an adrenaline autoinjector (all brands are similar and work the same way).

You can get adrenaline injection pens online from Allergy Pharmacy, or most pharmacies, and you don't need a prescription. The pens have an expiry date of one year and it's important to check this as an expired pen may not work. Although adrenalin isn't publicly-funded, ACC reimburse Epipen or Anapen when it is used as treatment for anaphylactic reactions. ACC may also provide cover for work and non-work related anaphylaxis.

What can I do if I'm at risk of anaphylaxis?

If you're at risk of anaphylaxis, talk to your doctor. You can ask them to help you complete an action plan that you can then keep with your adrenaline. The practice nurses at your general practice can give you and your whānau or family training in how to use an adrenaline injection pen.
