What is Anaphylaxis?

Anaphylaxis (pronounced ana-fil-ax-is) is a serious 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 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.

Supporting People With Serious Allergies

Here are some of the ways we support people to manage day-to-day life with a serious allergy.


About Anaphylaxis UK

Anaphylaxis UK is the only UK-wide charity operating solely for the growing numbers of people at risk of serious allergic reactions and anaphylaxis. While there’s no treatment or cure for anaphylaxis, we believe that by providing information, training and support, there is a brighter future for people living with serious allergies.

Our mission is to create a safer environment for everyone with allergies by working with and offering training for the food industry, schools, pre-schools, colleges, health professionals and others.
