Joe Crowley's discovery of unknown health issue – ‘not sure where they’ve come from'
The NHS advises if someone has anaphylaxis to:
1. Use an adrenaline auto-injector if the person has one – but make sure you know how to use it correctly first.
2. Call 999 for an ambulance immediately (even if they start to feel better) – mention that you think the person has anaphylaxis.
3. Remove any trigger if possible – for example, carefully remove any stinger stuck in the skin.
4. Lie the person down flat – unless they’re unconscious, pregnant or having breathing difficulties.
5. Give another injection after 5 to 15 minutes if the symptoms do not improve and a second auto-injector is available.
But common anaphylaxis triggers tend to include:
- foods – including nuts, milk, fish, shellfish, eggs and some fruits
- medicines – including some antibiotics and non-steroidal anti-inflammatory drugs (NSAIDs) like aspirin
- insect stings – particularly wasp and bee stings
- general anaesthetic
- contrast agents – dyes used in some medical tests to help certain areas of your body show up better on scans
- latex – a type of rubber found in some rubber gloves and condoms
