Why does anaphylaxis occur?

Anaphylaxis can occur in people who are exposed to an allergen to which they are allergic.1

The role of our immune system is to protect us from ‘foreign invaders’. In people with anaphylaxis, the immune system 'overreacts' to the allergen. Contact with, or ingestion of this allergen sets off a chain reaction in the immune system that may lead to anaphylaxis.5

Several factors can influence the severity of allergic reaction.1

  • Exercise
  • Heat
  • Alcohol
  • Food - the amount eaten, and how it is prepared.

How is anaphylaxis treated?

Anaphylaxis is both preventable and treatable.

Knowing your triggers and avoiding them is the best way to help prevent an anaphylactic event.1,6

A referral to a clinical immunology or allergy specialist will help you to identify your triggers and learn the best ways to avoid them and prevent anaphylaxis.1

However, no matter how careful you are, accidental exposure to a trigger can happen. That’s why it’s so important to be prepared.

Have an ASCIA Action Plan for anaphylaxis that you have discussed with your GP or specialist. The action plan will help you recognise symptoms of anaphylaxis, understand what steps to take if you or your child is experiencing anaphylaxis.

Make sure you always carry your EpiPen® Auto-Injector – and know how to use it.1,8

When a person is experiencing anaphylaxis, administer EpiPen® Auto-Injector as soon as possible.6

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.
