Useful advice 

• Do not inject into the buttock, hands, or feet.
• A second dose may be given after 5–15 minutes if symptoms persist and a second auto-injector is available.
• Always check the solution through the window—it should be clear and colourless; do not use if cloudy or discoloured.
• Always carry two devices in case a second dose is needed.
