If someone is having a severe allergic reaction, it is vital that they receive an adrenaline injection. If they have their own adrenaline, this must be given as soon as a severe reaction is suspected to be occurring and an ambulance must be called immediately. If the patient is alone or is unable to self-administer, the adrenaline should be administered first then an ambulance should be called immediately after.
Practical points:
- Try to ensure that a person suffering an allergic reaction remains as still as possible
- Preferably they should be lying down and if they are feeling weak, dizzy or appear pale and sweating their legs should be raised
- When dialling 999, say that the person is suffering from anaphylaxis (anna-fill-axis)
- Give clear and precise directions to the emergency operator, including the postcode of your location
- If adrenaline has been given, make a note of the time this was administered. A second dose can be given after five minutes if there has been no improvement
- If the person’s condition deteriorates after making the initial 999 call, a second call to the emergency services should be made to ensure an ambulance has been dispatched
- Send someone outside to direct the ambulance crew when they arrive
- Try to ascertain what food or substance may have caused the reaction and ensure the ambulance crew knows this.
