To take your insulin injection with a pen:

• Wash your hands with soap and water before injecting.
• Put a new needle onto your pen and dial up your dose.
• Raise a fold of fatty flesh slightly between your thumb and fingers.
• Put the needle in- if you are particularly slim, you may need to put the needle in at a 45 degree angle to avoid injecting into the muscle.
• Push the plunger, to inject the dose. Count at least 10 seconds.
• Remove the needle from the pen.
