Patient Considerations

Active Lifestyle

Limited Adjustability. No way to adjust long-acting insulin for higher activity on the fly, but the device is water-resistant. 

Water-resistant for up to 3 feet deep for 30 minutes and light on the body, does not get in the way of activity. The reader must be within 1.5 inches of the sensor to scan it. 

Avoiding Highs and Lows

Limited customizability. System requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day. 

Alerts are not available. High or low glucose alarms are not available. Trend arrows show the direction glucose is heading, with the rate of change. 

Comfort

Free of tubing. Patches do not have tubing, but it must be worn in areas that are easy to reach for insulin dosing. 

Lowest profile sensor and smallest adhesive.

Easy Insulin Dosing

Simple with few steps. 24-hour bolus range: up to 36 units per 24 hours, doses in 2-unit increments. Preset basal rate of 20, 30, or 40 units per 24 hours.

Scanned sensor readings can be used for dose adjustment.

Easy to Use

Simple with few steps. Patch is replaced every 24-hours with insulin administered at the click of a button. 

Requires scanning. Self-application and manual scanning every 8-hours are required. Easy self-application.

Fewer Fingersticks

Frequent finger-sticks are required.

Factory-calibrated sensor. Finger-sticks needed for backup only. 

Privacy

Hideable. Bulkier patch pump, but not as noticeable as injections. Bolus button can be used discreetly through clothing.

Somewhat discreet. Scanning feature makes it easy to monitor blood glucose levels discreetly.
