    Summary for Continuous glucose monitoring
    Prescription only

    Dexcom G7 15 Day is a continuous glucose monitoring (CGM) system used to help manage adults with diabetes by tracking glucose levels in real time without fingersticks. It uses a small sensor you wear on your skin to alert you when your blood sugar is too high or too low. The readings are then sent to a receiver, like your smartphone or a compatible insulin pump. Each sensor lasts up to 15 days before it needs to be replaced. Possible side effects include skin irritation or swelling at the application site.

    Summary for Continuous glucose monitoring
    Prescription only

    FreeStyle Libre 2 is a continuous glucose monitoring (CGM) system that's designed to replace fingersticks and lessen the need for test strips in people with diabetes. It measures your glucose levels every minute throughout the day to better help you manage your blood sugar. The FreeStyle Libre 2 system uses a sensor that's attached to your skin on the back of your upper arm. You can scan the sensor and have the glucose reading displayed on an app in your smartphone (compatible phones only), or the FreeStyle Libre 2 handheld reader. The sensor must be replaced every 14 days, and the sensors require a prescription.
