Patient Considerations
Active Lifestyle
Water-resistant transmitter when submerged in 1 meter of water for up to 30 minutes and must be within 25 feet of the connected smart device.
Light on body. Pens are easy to use and do not remain attached to the body, sensor is waterproof.
Avoiding Highs and Lows
On-body vibration alerts when blood glucose levels are higher or lower than the set range. Trend arrows show the direction glucose is heading, with the rate of change.
Limited customizability. System integrates the Guardian Connect CGM for high or low alerts but requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day.
Comfort
Longest lasting sensor fits comfortably under the skin. Minor procedure is required.
Many components. Have to carry InPen and pen needles. CGM is attached to the body and requires more tape than other sensors.
Easy Insulin Dosing
Predictive alerts make insulin dosing easier by tracking high and low trends.
Dosing recommendations. Displays dosing recommendations and reminders for long-acting insulin.
Easy to Use
Minor procedure. Requires insertion by a physician during a medical visit.
Simple design. Replaces regular insulin pen. No additional devices to add on.
Fewer Fingersticks
2 daily finger-sticks are needed to calibrate the sensor.
2 daily finger-sticks are needed to calibrate the sensor.
Privacy
Somewhat discreet. Tiny sensor is implanted under the skin, so the user can be discreet when needed. Ability to see sugar on watch or phone. Sensor not movable on body and requires regular meter use.
Hideable. Pens are portable but visible when in use. Frequent injections are unavoidable. View recommendations and data on a smartphone.
