Frequently Asked Questions

How does pen needle sizing work?

4mm refers to the length of the needle. Needle lengths range from 4mm to 12.7mm, so 4mm is the shortest length. Some people prefer short needles because they may improve comfort and reduce anxiety.

32G (32 gauge) represents the size of the needle's hole. It's important to note that a higher number signifies a smaller hole. For example, this 32G needle has a smaller hole than a 31G needle.

What's the difference between 1st and 2nd generation BD Nano pen needles?

1st gen BD Nano pen needles have three bevels on the needle's tip. BD Nano 2nd gen pen needles 4mm x 32G have PentaPoint comfort technology, which means they have five bevels, which may help to improve comfort.

The 2nd gen pen needles also have BD's innovative contoured base, which is designed to adapt to differing forces, which may help to improve consistency and reduce user error. The 1st gen pen needles have a straight, posted base.

The 2nd gen Nano needles also have ultra-thin wall technology that's designed to improve the flow of medication. A larger inner shield allows for easier gripping and removal during use. A wider outer cover allows for easier attachment to your insulin pen.

What technique should I use with BD Nano 2nd gen pen needles?

BD recommends using the needle straight with a “no pinch” technique. Some people may wish to hold the skin taut while dosing their medicine.

One of the BEST!

I only received the first box of BD needles along with my pen. After that, I wasn't covered for them. I found an online source for BD, paid $45. I wasn't happy with them; after a few months, half the time the needle was uncomfortable. So I decided to look for options. Found the ADW Diabetes website, and after reading lots of reviews, I ordered a box of these: they say BD, but they are actually Embecta. They are FAR SUPERIOR to any other BD. I NEVER feel the needle now. It's really great.

Nano Needles

The Nano needles are as good as the BD needles and less expensive than I was paying through my insurance.

IMO The Best Pen Needles On the Market

Have used several pen needle brands/styles and the BD Nano Ultra-Fine 2nd Gen are hands down the best design and quality. Noticeably less pain upon injection. And ADW is reliably fast with service and delivery.

Embecta 4 x 32 needles

I have always like this needle formerly made by BD. There is a large flat surface on which the needle rests when insulin is injected.
