Insulin pen needles and disposable syringes come in a variety of lengths and widths to suit all body types.

Needles used to be long and sharp, but due to evolutions in technology, needles are now small, thin and quite often pain-free.

From 12mm to 4mm, the needle length you choose is likely to be dictated by your size. Children will likely benefit from the shorter 6mm size.

Your healthcare team should be able to advise you on which is best your body shape. When it comes to injecting, it is essential to get the right kit and use the right technique to reduce any pain.

Hence, be careful not to fall into sloppy habits, such as failing to rotate your insulin injection sites as this might lead to irritation and soreness.

Use needles correctly

Make sure that along with rotating injection sites, you follow these rules for using needles correctly.

  • Use new needles either for every injection or at least change them once a day.
  • Do not inject through clothing (or only very rarely).

If you’re an ‘old hand’ at injecting, you might benefit from a quick refresher on how to inject to make sure you’re doing it correctly.

Needles ranges fit on most insulin pens

Most needle ranges fit on most insulin injection pens, including all Novo Nordisk and Eli Lilly pens (Novopens and Humapens) as well as the Autopen range from Owen Mumford.

All of these needles are available on prescription.

Gauges and needle length

The measurements of needles relate to how long the needle is. When a needles measurement is 31G, the G (or g) refers to the gauge of the needle. This donates the thickness, size, or capacity.

The gauge and needle length will contribute to perceptions of pain when injecting.

The longer the needle is, the harder it is to ‘pressurise’ the insulin through so it needs a bigger hole down the middle.
