Advanced bolus tracking and algorithms, along with intuitive reports, tell you and your patients more about their MDI therapy than ever before.

Patients can share their InPen data with you at any time. See when and how much your patients are dosing, and get full visibility into their blood glucose and carb intake. At their next appointment, you can collaborate and identify new ways to help achieve their goals.

The InPenTM requires a prescription. It is a home-use reusable pen injector for single-patient use by people with diabetes under the supervision of an adult caregiver, or by a patient age 7 and older for the self-injection of a desired dose of insulin. The pen injector is compatible with Lilly Humalog® U-100 3.0 mL cartridges, Novo Nordisk Novolog® U-100 3.0 mL cartridges, and Novo Nordisk Fiasp® U-100 3.0 mL cartridges and single-use detachable and disposable pen needles (not included). The pen injector allows the user to dial the desired dose from 0.5 to 30 units in one-half (1/2) unit increments.

The InPenTM dose calculator, a component of the InPenTM app, is indicated for the management of diabetes by people with diabetes under the supervision of an adult caregiver, or by a patient age 7 and older for calculating an insulin dose or carbohydrate intake based on user entered data.

For an insulin dose based on amount of carbohydrates, a healthcare professional must provide patient-specific target blood glucose, insulin-to-carbohydrate ratio, insulin sensitivity parameters, and duration of insulin action to be programmed into the software prior to use as it is required for set up.

For an insulin dose based on fixed/variable meal sizes, a healthcare professional must provide patient-specific fixed doses/meal sizes to be programmed into the software prior to use.
