Anaphylaxis or a severe allergic reaction is a life threatening emergency. It is caused by the overwhelming reaction of the body’s immune system to a specific substance that the body incorrectly thinks is attacking it. Common substances, or allergens, include: peanuts, nuts in general, some foods, latex, insect stings, and certain drugs.
In as many as 1 in 4 cases of anaphylaxis no trigger can be identified despite extensive testing.
This type of anaphylaxis is known as idiopathic anaphylaxis.
Common symptoms of anaphylaxis include:
- Very rapid onset of:
- Swelling of the lips, tongue or throat
- Generalized rash including hives with itching and skin redness
- Wheeze and/or difficulty breathing
- Collapse, fainting or falling due to low blood pressure
An injection of a drug called adrenaline should be given as soon as there is concern that an anaphylactic reaction is starting. If needed, adrenaline is administered using a pre-filled injection device. There are four different devices available in Ireland and it is important that you request the device that you are familiar with, as there are variations in how each device is operated.
Being trained to use an adrenaline pre-filled syringe is only one part of being safe if you have a severe allergy. You should also ensure:
- You are educated and informed about your allergy and how to reduce your risk of a severe allergic reaction.
- You check the ingredients in your food. Don’t be afraid to ask questions about potential allergens when eating outside of your home!
- You inform family, friends and work colleagues about your allergy.
- Wear an allergy bracelet
- You are aware of the potential early signs of a severe allergic/ anaphylactic reaction and what to do in this situation.
