If you do not have access to a blood glucose meter when you receive a calibration prompt, your Eversense E3 CGM system will continue to provide glucose readings for up to 4 additional hours. You should take action during this time to obtain your blood glucose meter. After the 4 hours, you will receive a Calibration Past Due alert and no glucose values will be displayed until the next calibration is entered.
Even with a non-adjunctive CGM system, you should always carry a blood glucose meter with you as you should always be prepared to take a blood glucose test when prompted for a calibration or when any of the following situations occur:
- Your symptoms do not match the glucose value displayed on your app
- No glucose value is displayed (during system initialization, for example)
- Your system prompts you to use your BG meter for making a treatment decision in the app status bar
- You are taking medications of the tetracycline class
Yes, to make it clearer to users about the status of their calibration entry, during the 15 minutes after a calibration is entered and calibration by the system is in progress, the blood drop on the Home Screen trend graph will be grey. Once calibration is accepted, the drop will turn red. If the transmitter is removed during the 15 minutes that calibration is in progress, the blood drop will be black.
Once a new sensor is inserted by your health care professional and paired with the transmitter using the Eversense® App, it will start the 24-hour warm-up phase. Once the 24-hour warm-up phase is completed, you will begin the Initialization Phase.
Initialization Phase (after 24-hour Warm-Up Phase)
During this phase, 4 finger stick blood glucose meter tests are required.
- The 4 calibration tests must be spaced 2 to 12 hours apart, and all 4 tests must be completed within a 36 hour period.
– 1st calibration = 24 hours after sensor insertion.
– 2nd calibration = 2 to 12 hours after 1st successful calibration.
– 3rd calibration = 2 to 12 hours after 2nd successful calibration.
– 4th calibration = 2 to 12 hours after 3rd successful calibration.
- Glucose readings will start displaying in the app a few minutes after the 2nd calibration is successfully completed.

The Eversense® E3 Continuous Glucose Monitoring (CGM) System is indicated for continually measuring glucose levels for up to 180 days in persons with diabetes age 18 and older. The system is indicated for use to replace fingerstick blood glucose (BG) measurements for diabetes treatment decisions. Fingerstick BG measurements are still required for calibration primarily one time a day after day 21, and when symptoms do not match CGM information or when taking medications of the tetracycline class. The sensor insertion and removal procedures are performed by a health care provider. The Eversense E3 CGM System is a prescription device; patients should talk to their health care provider to learn more.
The Eversense® 365 Continuous Glucose Monitoring (CGM) System is indicated for continually measuring glucose levels for up to one year in people (18 years and older) with diabetes. The system is indicated for use to replace fingerstick blood glucose (BG) measurements for diabetes treatment decisions. Fingerstick BG measurements are required for calibration one time a week after day 13, and when symptoms do not match CGM information or when taking medications of the tetracycline class. The sensor insertion and removal procedures are performed by a health care provider. The Eversense 365 CGM System is a prescription device; patients should talk to their health care provider to learn more.
