McKesson Safety Insulin Pen Needle, 31 Gauge, 5 mm

The McKesson Safety Insulin Pen Needle is designed to make daily insulin injections safer and more comfortable for patients managing diabetes at home or in a clinical setting. Featuring a fine 31 gauge needle and a 5 mm length, this pen needle is built to minimize discomfort while delivering an accurate, consistent dose with every injection.

Each needle includes active back-end protection with an automatic lock-out mechanism. Once used, red stripes appear to clearly indicate that the needle has been engaged and is ready for safe disposal, helping reduce the risk of accidental needlestick injuries for patients and caregivers alike.

A clear viewing window allows users to visually confirm the needle tip during priming, helping prevent unnecessary waste of medication. The wing-shaped design provides a secure, comfortable grip during attachment and removal, while the regular bevel and thin, stainless steel construction support smooth, low-pain injections for individuals who require daily insulin therapy.

Trusted by healthcare professionals and home users, this insulin pen needle is a reliable choice for anyone seeking a safer, more comfortable injection experience.
