What is Anaphylaxis

Anaphylaxis (pronounced ana-fil-ax-is) is a severe and often sudden allergic reaction. It can occur when
someone with allergies is exposed to something they are allergic to (known as an allergen). Reactions usually
begin within minutes and rapidly progress but can occur up to 2-3 hours later.

Anaphylaxis is potentially life-threatening, and always requires an immediate emergency response.

If you or your child have had anaphylaxis, our Factsheet will help you understand more about the condition:
what anaphylaxis is, what causes it, the treatments and other vital facts. If you have experienced a sudden
allergic reaction in the past, then you may be at risk of anaphylaxis even if you have not had anaphylaxis
before. We advise that you see your GP and ask for a referral to an allergy clinic.

A diagnosis of anaphylaxis can be daunting at first, but by becoming well-informed, thinking ahead and
employing daily coping strategies, people affected find that life can return, almost, to normal.
