V-Go Patch
Freestyle Libre 3
Summary
V-Go is a convenient credit card-size patch pump that adheres to the skin and can be worn for 24 hours. This system is designed to be used with fast-acting insulin for people with type 2 diabetes who require 20, 30, or 40 units of insulin per day. Users can administer two units of insulin with every press of a button on the device. This device is a hybrid between injections and an insulin pump to allow for discreet dosing without the need for programming or multiple injections.
FDA-approved for people 21 years of age and older with type 2 diabetes.
The FreeStyle Libre 3 is the smallest, thinnest, all-in-one glucose sensor/transmitter CGM and lasts 14 days.

Optional low and high blood sugar notifications are available for this system.
FDA approved for insertion on the back of the upper arm (ages 4 years and older).
MARD of 7.9%.

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.
Avoiding Highs and Lows
Limited customizability. System requires manual dose adjustment and limits the ability to adjust insulin levels throughout the day.
Optional glucose alerts for low and high glucose levels. 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 (about the size of two stacked U.S pennies).
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.
Sensor trends 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.
No scanning required. Minute-by-minute readings are sent directly to the mobile app.
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.
Hypoglycemia safety alarm. Discreet size but built-in hypoglycemia safety alarm alerts users when glucose is below 55 mg/dl and is always on.
