Severe allergic reaction — act immediately
Inject into outer mid-thigh
Through clothing is fine. Hold firm for 10 seconds. Remove and rub the site for 10 seconds.
If symptoms return after 5–10 minutes
Use a second EpiPen if available. This is why NHS guidelines say always carry two.
Not sure if you should use it? If you have an EpiPen and you think it is anaphylaxis — use it. The risk of not using it is greater than the risk of using it unnecessarily.
Tell the operator:
If conscious
Lie flat, legs raised (unless breathing is difficult)
If breathing is difficult
Sit upright or in position of comfort — do NOT force flat
If unconscious
Recovery position (on their side). Begin CPR if no breathing.
Do NOT let them stand or walk — even if they say they feel better. Biphasic reactions can occur 1–8 hours later.
Stay with them
Do not leave the person alone under any circumstances.
Keep them still
Avoid any unnecessary movement.
Note the time
Record when symptoms started and when EpiPen was used. Tell the paramedics.
Remove the trigger
If a sting — scrape it off. If a food — do not induce vomiting.
Reassure them
Stay calm and keep them talking if conscious.
Reactions typically involve two or more body systems within minutes of exposure. Any ONE of the following alone from the severe column is enough to act.
Mild / Moderate (watch, give antihistamine)
