  • Summary of Dexcom G6 vs. Freestyle Libre 3

    Summary for Continuous glucose monitoring
    Prescription only

    Dexcom G6 is a continuous glucose monitoring (CGM) system that tracks your glucose levels every 5 minutes throughout the day. The system is made up of a sensor, transmitter, and receiver. You can insert the sensor on skin areas, such as the back of the upper arm or belly. Each sensor can be worn up to 10 days, then must be replaced after that. The transmitter, which delivers glucose readings to a receiver, has a lifespan of 3 months. If your phone is compatible with the Dexcom G6 system, the readings can go directly to your phone through the Dexcom G6 application (app).

    Summary for Continuous glucose monitoring
    Prescription only

    FreeStyle Libre 3 is a continuous glucose monitoring (CGM) system that you wear on your skin. It's designed to replace fingersticks for people ages 4 years and older with diabetes. It measures your glucose level every minute throughout the day to better help you manage your blood sugar. The FreeStyle Libre 3 system uses a sensor that's attached to your skin, which can be scanned and read using an app on a smart device (e.g., smartphone). It doesn't include a reader, and it's important to check phone compatibility to make sure the FreeStyle Libre 3 app will work properly.
