BD Nano™ 4mm pen needle
Make the great decision to get the smallest pen needle
The BD Nano™ 4mm pen needle is our smallest, thinnest pen needle, promoting comfort.1 The pen needle incorporates EasyFlow™ technology, which improves insulin flow through the needle and makes the device easier to use, even for users with hand-strength challenges—enabling users to receive their full dose.1 The pen needle also features the patented PentaPoint™ Comfort five-bevel needle tip to promote a more comfortable and easier injection, compared to a three-bevel needle.2
Less required thumb force
The pen needle requires 62% lower force to press the button,2 earning the Arthritis Foundation Ease of Use Commendation.3
Higher flow rate*
A large inner diameter allows insulin to flow more easily, providing a 149% higher flow rate than other leading pen needles.2
Improved insulin absorption
The pen needle is estimated to inject insulin into the fat layer more than 99.5% of the time—at all injection sites,4 promoting consistent absorption and reducing the risk of intramuscular (IM) injections that can cause hypoglycemia.
The five-bevel needle tip vs the three-bevel tip of other leading brands enables the pen needle to penetrate the skin more easily and facilitates a smoother, gentler injection by providing a flatter, thinner surface.1
Varying sizes accommodating various needs
The BD Ultra-Fine™ brand also comes in 5-mm and 8-mm sizes.
