BD Ultra-Fine™ Nano™ Pen Needles

63% of people with diabetes are using the same needle length they started on at diagnosis.1

Research no longer supports the recommendation of long needles.1,2

Introducing BD Ultra-Fine™ Nano™ 4mm Pen Needles with Pentapoint™ comfort and EasyFlow™ technology.

EasyFlow Technology

EasyFlow™ Technology

BD Nano™ 4mm Pen Needles now with Extra Thin Wall Technology improves the insulin flow through the needle, making injections more convenient, including for people with hand-strength challenges.5

PentaPoint™ Comfort

BD Nano™ 4mm Pen Needles are the first and only pen needles with patented 5-bevel technology. The flatter, thinner needle tip eases into the skin with less force, clinically demonstrated to reduce the pain of injection.4

100% Compatibility

100% compatibility guaranteed with all insulin and GLP-1 pens in Canada*

BD Nano™ 4mm supports optimal injection technique.

The body is covered with skin. Underneath the skin there's a layer of fat (subcutaneous tissue). Below that is a layer of muscle.

Average skin thickness ranges from 1.6 - 2.4 mm within the four most common injection sites.6,7 To be absorbed properly, insulin or GLP-1 needs to be injected into the subcutaneous tissue layer, just under the skin. If the needle goes deeper, the dose may go into the muscle.

An injection into your muscle will likely hurt and speed up your insulin absorption which can cause a low blood sugar. The preferred areas used for injection are your adomen, thighs and buttocks. The back of your arm may also be used. Being small has it's advantages. In addition to increased comfort when using a 4 mm pen needle, you don't need to perform a skin lift in order to achieve a subcutaneous injection.* You can use a simple, one-handed injection for all injection sites: arms, thighs, abdomen and buttocks. Talk to your doctor or diabetes educator about the sites that are best for you.
