You may not get the full wear time from your sensor if you end it early.
If you end your session early, you will need a new sensor to continue monitoring.
How do I remove the sensor?
After your sensor session ends, peel off the patch like a bandage.
To make it easier and to avoid irritating your skin, try these tips:
Loosen edge and soak patch in body oil, like baby oil or an adhesive remover for skin (see product instructions before using).
Use adhesive removal wipes for skin, rubbing exposed skin as you peel back the patch.
Try different pulling techniques:
Pull off the patch slowly, folding it over itself, in the same direction of hair growth.
Stretch loosened edge and push your fingers under the patch to pull it off skin.
Important Notes
For all Dexcom systems, you can only have one active sensor session at a time.
Do not reuse sensor codes or attempt to restart a used sensor.
If you experience discomfort, adhesive issues, or sensor errors, early replacement is recommended.
