InPen helps reduce the mental math of diabetes management.


How does it work?

The InPen system helps you take the right amount of insulin, at the right time. It calculates personalized meal and correction doses - considering your insulin sensitivity, insulin-to-carb ratio, and active insulin levels for each dose recommendation. The system also logs doses on a mobile app, allowing you to see your dose history on a smartphone.

Cartridges are not included with InPen. You’ll need a separate prescription for cartridges. Cartridges can be ordered from the same pharmacy where you get your other diabetes supplies. InPen is compatible with Humalog, Novolog, and Fiasp U-100 3.0 mL insulin cartridges.
The InPen app allows you to manually log your long-acting insulin doses and set up dose reminders to take your long-acting insulin. InPen works with the following short-acting insulins: Novolog, Humalog, and Fiasp.

Yes, you can pair as many InPens as you need to the app. This enables the flexibility for you to have one InPen at home and another at work or school.

Note: Make sure your paired device is within range of your InPen when you dose. Your InPen app will automatically sync doses from all paired InPen(s) when within range.

Active insulin, also known as insulin on board (IOB), is an estimate of how much insulin from recent doses is still active in your body. For example, if you take a 5 unit dose, there will initially be a full 5.0 units in your body. Over several hours, this will decrease as your body uses the insulin. The InPen app shows active insulin from rapid-acting or mealtime insulin only, not long-acting or basal insulin.
Active insulin is shown on the home screen below the calculate dose button. This number shows your total active insulin based on all rapid-acting and mealtime doses from the past eight hours.
Yes, the i-Port Advance injection port is compatible with the InPen. Needles used with the i-Port Advance injection port need to be 5-8 mm (3/16-5/16”) in length and 32-28 gauge.
Yes, the integration is compatible with both iOS and Android devices; however, you should check compatibility for both the Guardian Connect system and the InPen app prior to ordering.
