Your Dexcom G6 transmitter is designed to last three months and can be used across multiple sensor sessions. Starting three weeks before replacement is needed, the device will alert you, ensuring you have ample time to prepare. If you have only one transmitter, contact Dexcom to order a replacement.
Note: When the Dexcom G6 transmitter has less than 10 days of battery life remaining, starting a new sensor session will no longer be possible.
Use the following steps to remove your Dexcom G6 sensor and transmitter:
- Peel the edge of the adhesive patch up and away from your body
- Break the purple holder at the notches
- Slide the transmitter out of the holder and keep it to use with the next sensor
- Throw out the adhesive patch according to your local guidelines for disposal of blood-contacting components
