FAQS
What if the FreeStyle Libre 2 sensor falls off before 14 days of use?
Replace the FreeStyle Libre 2 sensor and start a new sensor. If the sensor falls off early, please call us at 1-800-915-5924.
What happens to the FreeStyle Libre 2 sensor after the 14 day wear period?
After 14 days of wear, the reader notifies you that the FreeStyle Libre 2 sensor has ended and should be replaced with a new sensor.
Can a user still scan the FreeStyle Libre 2 sensor and get the last 8 hours of data after the sensor has ended after 14 days?
The user is provided with one last opportunity to scan the FreeStyle Libre 2 sensor after the 14 days have ended.
Does the FreeStyle Libre 2 system contain latex?
The FreeStyle Libre 2 system does not contain any latex.
Can the FreeStyle Libre 2 sensor be applied to tattooed skin?
Yes, there is no interaction expected between tattoo ink and the FreeStyle Libre 2 sensor. It is advised to avoid areas with scars, moles, stretch marks or lumps when applying the sensor.
Why do the numbers on the FreeStyle Libre 2 sensor pack and sensor applicator need to match?
The FreeStyle Libre 2 sensor pack and sensor applicator need to match because the sensor is factory calibrated. Information about the calibration of the sensing element (also known as the sensor tip) is programmed in the sensor at the factory and these two components must be used together.
What happens if the FreeStyle Libre 2 sensor is worn beyond 14 days?
The FreeStyle Libre 2 sensor automatically stops collecting glucose data and should be removed 14 days after being started. Three days before the sensor ends, it tells users with the first scan of each day. In the final 8 hours, it tells users with each scan. The sensor should be replaced with a new sensor.
What are the potential skin reactions to the FreeStyle Libre 2 sensor?
Some individuals may be sensitive to the adhesive that keeps the sensor attached to the skin. If you notice significant skin irritation around or under your sensor, remove the sensor and stop using the FreeStyle Libre 2 system. Contact your health care professional before continuing to use the FreeStyle Libre 2 system.
Were there any skin reactions reported by patients wearing the FreeStyle Libre 2 sensor?
In the adult study, mild skin irritations, such as erythema, bruising, bleeding, and scabbing were reported around the insertion site and adhesive area by a small number of subjects (6.8%)1.
Were there any adverse events reported by patients wearing the FreeStyle Libre 14 day or FreeStyle Libre 2 sensors?
No device related serious adverse events occurred during the studies. In the Adult study, mild skin irritations, such as erythema, bruising, bleeding, and scabbing were reported around the insertion site and adhesive area by a small number of subjects (6.8%). Pain was mostly reported as none with only one instance of mild pain. In the Pediatric study, there were 8 instances of erythema (4 “well-defined redness”, and 4 “slight pink”), 5 instances of edema (3 slight edema, 2 slight edema with defined edges), 2 instances of mild bleeding, one instance of mild induration and one instance of mild rash1.
Is there any problem with the FreeStyle Libre 2 sensor if you sweat a lot?
Intense exercise may cause your FreeStyle Libre 2 sensor to loosen due to sweat or movement of the sensor. If the sensor is becoming loose or if the sensor tip is coming out of your skin, you may get no readings or unreliable low readings. Remove and replace your sensor if it starts to loosen and follow the instructions to select an appropriate application site. Do not attempt to reinsert the sensor. Contact Customer Service if your sensor becomes loose or falls off before the end of the wear period. Customer Service is available at 1-855-632-8658 7 days a week from 8AM to 8PM Eastern Standard Time.
What if the user needs to remove the FreeStyle Libre 2 sensor before 14 days (or if it falls off)?
A FreeStyle Libre 2 sensor that has been removed or that has fallen off cannot be reused. Users should replace the sensor and start a new sensor. The FreeStyle Libre 2 reader will identify that it is a new sensor and ask users if they want to start it.
Can a user still scan the FreeStyle Libre 2 sensor and get the last 8 hours of data after the sensor has ended after 14 days?
The user is provided with one last opportunity to scan the FreeStyle Libre 2 sensor after the 14 days have ended. The reader will acquire any data remaining on the sensor that was obtained prior to the end of the 14 day wear period.
When I scan my FreeStyle Libre 2 sensor, the reader says Sensor Ended, but I have not worn my sensor for the intended wear period. What should I do?
If for any reason the FreeStyle Libre 2 sensor stops working, please call Customer Service at 1-800-915-5924.
The FreeStyle Libre 2 sensor will expire within 14 days, can I still start the sensor?
Do not use the FreeStyle Libre 2 sensor past the expiration date. If your sensor expires during the 14 day wear, start a new sensor before the sensor expires.
Will you update the FreeStyle Libre 2 sensors to last longer than 14 days?
At this time, there are no current plans to update the FreeStyle Libre 2 sensors to last beyond the 14 days. Research has shown that 14 days of glucose data is sufficient to produce daily glucose patterns with certainty approaching 90%1.
Does the expiration date on the FreeStyle Libre 2 sensor indicate the last day the user can apply the sensor, or the last day it can be used?
The expiration date indicates the last day you can use the sensor. Do not use the FreeStyle Libre 2 sensor past the expiration date. If your sensor expires during the 14 day wear, start a new sensor before the sensor expires.
