A reusable injector pen plus an intuitive smartphone interface equals smart insulin delivery. Simplify your diabetes care plan.

Reusable Diabetes Injector Pen

The Pen

The InPen insulin injector pen. An easy-to-use pen that not only helps calculate your doses but also keeps track of injection data.

When paired via Bluetooth® with the smartphone app, the InPen delivery system keeps tabs on how many units you received at your last injection, when you took them, and other helpful information.

InPen was designed for insulin-dependent individuals 12 and older undergoing multiple daily subcutaneous injections. It can deliver 0.5 to 30 units of insulin, dialed in half-unit increments. Dial too many units? Not a problem. InPen lets you correct the dose without wasting insulin.

The InPen injector pen is compatible with Lilly Humalog® and Novo Nordisk Novolog® U-100 3.0 mL insulin cartridges and single-use detachable and disposable needles (not included).

InPen is as easy to maintain as it is to use. The InPen lasts for one year – no recharging needed. And with options in blue, grey, and pink, you can even add a bit of color to your management plan.

The App

The InPen app is the other half of InPen’s smart diabetes management tool. Using information transmitted from the pen, the app can track insulin therapy, calculate doses, share therapy data with your doctor or family, and much more.
