You should be referred to a specialist allergy clinic for tests to find out what caused the anaphylaxis. Knowing what allergen triggered the allergic reaction can help you avoid further episodes of anaphylaxis.
Some of the tests commonly used to determine allergies include:
You may be prescribed an adrenaline auto-injector if you’ve had a previous episode of anaphylaxis and there’s a risk of you having another episode in the future.

Each type is slightly different, and you should make sure you know how to use your auto-injector correctly.
You can also ask for a “trainer” kit so you can practise giving yourself or your child injections.

Always tell any healthcare professional about medicine allergies you have, as they may not be aware of them.
There may be times when it’s necessary to use contrast agents – for example, if you had bleeding inside your brain – even if this places you at risk of anaphylaxis.
In such circumstances, you can be given injections of antihistamines and corticosteroids before the contrast agents, which may help prevent symptoms occurring or at least make them less severe.
