InPen™ helps solve common MDI challenges
Missing 2 doses per week can lead to an increase in A1C of up to 0.4%1
2 out of 3 people need help calculating their doses and 60% of doses are stacked2–4
Lack of accurate dosing data is a barrier to optimizing glycemic control5
The use of a bolus calculator is associated with a 0.7–1.0% reduction in A1C6–8
Patient data in one convenient place
Integrated, reliable diabetes data
InPen™ Insights Reports provide a way to view a patient’s glucose, carbohydrate, and insulin dosing data from their InPen system.
Easy collaboration
InPen™ Insights Reports help providers assess a patient’s insulin doses and glycemic levels, regardless of which multiple daily injection regimen the patient is following.
