BD Nano™ 4mm Pen Needles


Why BD Nano™ 4mm Pen Needles?

Insulin is meant to be injected into the fat layer just below the skin for consistent absorption.1
If you inject into a muscle, the insulin can work too quickly, which may lead to low blood sugar.2 
The BD Nano™4mm Pen Needle, BD’s shortest pen needle gets insulin to the fat layer over 99.5% of the time, at all injection sites.3


Ask your doctor if the BD Nano 4mm Pen Needle is right for you.
