For the Dexcom G6 CGM, please follow these steps to remove a sensor and transmitter:

1) Your G6 CGM will let you know when to replace the sensor.

2) Grab the edge of the adhesive patch. Peel adhesive patch up and away from your body like a Band-Aid®.

3) Break the purple transmitter holder at notches.

4) Slide the transmitter out of the holder. Keep transmitter to use with the next sensor. Throw out the adhesive patch according to your local guidelines for disposal of blood-contacting components.

Reuse your transmitter

Your transmitter lasts 3 months. Reuse it for multiple sensor sessions. Your G6 tells you when your transmitter will need to be replaced, starting 3 weeks before. If it is your only transmitter, contact Dexcom to order another. When the transmitter has less than 10 days of battery life left, you won’t be able to start a new sensor session.
