How to inject 

At-a-glance instructions:


Pen cap removed

Check your pen

Check the name and coloured label of your pen to make sure that it contains the right medicine

Pull off the pen cap and make sure the medicine inside is clear and colourless*

Attaching needle

Attach a new needle

Remove the paper tab from a new needle

Push the needle straight onto the end of the pen and push the needle straight on. Turn until it is on tight

Pull off both needle caps. Keep the big outer needle cap for later

Pushing button

Check the flow

Turn the dose selector to select 2 units

Press and hold the push button all the way in while holding the pen upright. The dose selector returns to 0. A drop of medicine should appear at the needle tip. This removes air bubbles and gaps, and ensures the medicine is flowing properly

Turning dose selector

Select your dose

Check that the dose selector is set at 0

Turn the dose selector to select the number of units you need to inject

You can turn the dose selector up or down to adjust the dose

Injecting insulin

Inject your dose

Insert the needle into your skin

Press the push button all the way in until 0 lines up with the pointer

Keep the push-button fully depressed and let the needle remain under the skin for at least 6 seconds. This will make sure you get the full dose

Removing needle

Remove the needle

Lead the needle into the big outer needle cap without touching it. When the needle is covered, carefully push the big outer needle cap completely on and then unscrew the needle

Unscrew the needle and safely throw it away

Then put the pen cap back on

*If you have been prescribed a premixed suspension such as biphasic insulin aspart, it will not be see-through. You will then have to re-suspend your medicine: Hold the pen horizontally between your palms and roll it 10 times, then move the pen up and down 10 times. Make sure that the medicine is uniformly white and cloudy.

Never share your pen with
anyone else – stick to the
‘one pen, one person’ rule!

Correct needle disposal

To reduce the risk of injury to others, pen needles should be disposed of in a puncture-resistant container, such as a “sharps container”, according to local regulations. Check local recommendations for discarding medical waste.
