How long can I wear the Dexcom G7 sensor?
Each Dexcom G7 Continuous Glucose Monitoring (CGM) System sensor session lasts up to 10 days with a 12-hour grace period at the end.
The Dexcom G7 grace period gives you more time to replace your diabetes sensor so you can do it at the time of the day when it's convenient for you.1 The time left in the grace period shows on your display device* screen. During the grace period, your Dexcom sensor continues to work just as it did during the sensor session.
You'll get Dexcom alerts on your app* or receiver* letting you know that your sensor session or grace period will end soon. You can choose to wear the sensor until the grace period ends or end the session early.
To find out how much time you have left in your sensor session, go to Connections > Sensor in the app*, or in the receiver*, go to Menu > Information > Sensor > Sensor Info. When the sensor expires, the 12-hour grace period starts.
Sensor Transition
You must end the sensor session or grace period before you start a new sensor. You can end it two ways:
- Automatically: when the grace period ends (you'll get an alert letting you know)
- Manually: before the grace period ends
You only need to end your Dexcom sensor session on one display device.*
View the Dexcom G7 User Guide for more information on ending your sensor session automatically or manually.
* Display devices sold separately. For a list of compatible smart devices, please visit www.dexcom.com/compatibility. The optional receiver may be purchased through the Dexcom Store.
