Features and Benefits

Accuracy

The Nano™ 4mm  Pen Needle helps to reduce the risk of injecting into your muscle compared to needles 6mm and longer. 3*

Comfort

The Nano™ 4mm  Pen Needle can significantly help reduce pain during injection compared to larger and longer pen needles.4 The 5-bevel needle tip can bring a more comfortable and less painful injection. 5^

Confidence

The Nano™ 4mm Pen Needle has Ultra-Thin wall technology to increase the flow of insulin so less thumb pressure is needed to push the pen button—making it easier for you to give the injection and giving you confidence that you have received the full dose of insulin.6¥

Compatibility

Nano™ 4mm Pen Needles are compatible with widely used pen injection devices, so even if your regimen changes, you won’t have to change your choice of pen needle.7

Single Use 

Use a new pen needle every time you inject. Pen needles are recommended to be used only once and are no longer sterile after that.2

«Results from a patient survey.

*Estimates based on 90-degree insertion with no skin pinch-up.

^Patients were aware of the pen needle they were using.

¥Ultra-thin wall was introduced as an ISO standard for inner wall diameter in 2016.
