How to rehearse before the first injection

Most of a first injection is sequence, not nerve. What you can safely rehearse beforehand, what to ask for, and what never to practise.

Key points

  • 01Rehearse the sequence with the cap on. Lay out the supplies, wash your hands, open the sharps container, hold the device the way the leaflet shows, and talk yourself through each step out loud. Every part of a first injection except the needle can be practised the evening before, and the sequence is the part people actually fumble.
  • 02Ask whether a training device is available. Manufacturers supply demonstration pens that contain no medicine, and clinics and pharmacies often keep one for teaching. Handling a device with the same dial, the same clicks and no consequences is worth more than any number of videos. It costs one question at the counter.
  • 03Practise the position before the procedure. Sit where you will actually inject, find the site, pick up the skin fold if your technique calls for one, and hold it. Deciding where to sit, how to reach and what to do with your other hand is most of what feels awkward on the day, and none of it needs a needle.
  • 04Practise the count out loud. Holding the device in place after delivery is the step people cut short, and the leaflet for your device names the number of seconds. Counting it out loud a few times in rehearsal makes it automatic, and our post on how long to leave the needle in explains why that count exists.
  • 05Book a watched first dose. Ask your prescriber or pharmacy whether someone can watch your first real injection. One observed attempt catches the small habits, an angle, a rushed withdrawal, a forgotten site rotation, before they become the way you do it for a year. This is a normal request, not a special favour.
  • 06What not to practise. Do not dial and fire doses into the air to get used to the sound, because each one leaves the pen and the doses are counted. Do not practise on fruit with a needle you then intend to use, and do not inject anything, including water, that was not prescribed to you.

Frequently asked questions

Can I practise with my real pen?+

You can rehearse everything with the cap on, including handling, positioning and the count. What you should not do is release doses into the air to get used to it, since those doses leave the device. Not medical advice.

Are training pens a real thing?+

Yes. Demonstration devices that contain no medicine exist for the major pens, and clinics and pharmacies often keep one for teaching. Ask whether yours has one available.

Should I practise on an orange?+

It is a long-standing teaching aid in nursing education for syringe handling, and if you use it, it is with a spare needle that then goes into the sharps container, never one you intend to inject with.

How many rehearsals are enough?+

Usually two or three, spread out rather than repeated once. The goal is knowing the order of steps without reading them, not perfecting anything.
