Overview

A recent study showed that people with diabetes were making at least 1 mistake in how they inject insulin. 1,2<< This can lead to insulin not working the way it should.2

Features and Benefits

Accuracy

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

Comfort

The Micro-Fine™ 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 Micro-Fine™ 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 to give the injection and giving your patients confidence the full dose of insulin was received.6¥

Compatibility

Micro-Fine™ 4mm Pen Needles are compatible with widely used pen injection devices, so even if your patient's treatment regimen changes, you wonʼt have to change your choice of pen needle for them.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

<< 230 patients with diabetes surveyed as part of a cross-sectional observational behavioral study in Canada.
*Estimates based on 90-degree insertion with no skin pinch-up.
^ 86 patients with diabetes used to evaluate differences between 5-bevel and 3-bevel pen needle tips across pen needles (PN) of equal length and gauge. The 5-bevel PN would be considered more comfortable if the 95% lower bound for the percentage of insertions was greater than the 95% upper bound. After subjects were informed, the 5-bevel PN was selected more often than the 3-bevel PN for greater comfort (p = 0.01)in home use. When patients were blinded to the PN bevel designs, no differences were found for ease of insertion (37.1%, 36.8%), comfort (37.1%, 37.6%).
¥ 198 patients with diabetes were included in this prospective, multicenter, randomized, open-label, 2- period, crossover study to evaluate differences in perceived thumb force and in confidence that the full dose of insulin was delivered, between the participants’ usual pen needle (PN) and the corresponding extra-thin wall (XTW) pen needle. Significant differences favoring XTW pen needles were seen for perceived thumb force and confidence that the full dose was delivered by 28.4mm (95% CI, 23.7-33.2), and 24.4mm(95% CI, 19.7-29.1), respectively; (all, P<0.001). Ultra-thin wall was introduced as an ISO standard for inner wall diameter in 2016.
