    Summary for Continuous glucose monitoring
    Prescription only

    FreeStyle Libre 14 Day is a continuous glucose monitoring (CGM) system that you wear on your skin. It's designed to replace fingersticks in adults with diabetes. It measures your glucose (sugar) levels every minute throughout the day to better help you keep track of your daily patterns. The FreeStyle Libre 14 Day system uses a 14-day sensor that's inserted in your skin. It sends your glucose readings directly to your smartphone (through an app) or the FreeStyle Libre 14 Day handheld reader.

    Summary for Continuous glucose monitoring
    Prescription only

    Dexcom G7 is a continuous glucose monitoring (CGM) system. It helps adults and children ages 2 years and older living with diabetes keep track of their glucose levels in real-time without fingersticks. Dexcom G7 comes with a sensor you wear on the skin that's held in place with an overpatch. There's a transmitter that's pre-assembled with the sensor that sends your glucose readings to a receiver (e.g., smartphone or compatible insulin pump). Each sensor can be worn up to 10 days, then must be replaced after that. Calibration with a glucometer is optional, not required.
