Frequently Asked Questions

SENSOR APPLICATION
How is the sensor applied to the body?
The sensor is applied to the back of the upper arm with a simple, disposable device called an applicator. When the sensor is applied, a small
(5mm) filament is inserted just under the skin, and held in place with a small adhesive pad. Most users don't feel pain when applying the
FreeStyle Libre 2 sensor.

Is it necessary to apply a sensor in a different location if the user feels discomfort?
To prevent discomfort or skin irritation, you should select a different site other than the one most recently used or on the back of the other arm.
When applying the sensor to the arm, should the skin be stretched or pinched?
No, there is no need to stretch or pinch the skin to apply the sensor. The sensor should be applied only on the back of your upper arm. Avoid
areas with scars, moles, stretch marks, or lumps. Select an area of skin that generally stays flat during normal daily activities (no bending or
folding). Choose a site that is at least 2.5 cm (1 inch) away from an insulin injection site. To prevent discomfort or skin irritation, you should
select a different site other than the one most recently used or on the back of the other arm. For more information please refer to the
FreeStyle Libre 2 User's Manual.
SENSOR WEAR
Will the user feel the sensor while wearing it?
The portion of the sensor that gets inserted under the skin is less than 0.4 millimeter wide (1mm is about the thickness of a few strands of
human hair) and it's inserted only about 5mm under the skin, so most people will not feel the sensor while it is being worn.*
Can users bathe, shower, swim or exercise while wearing a sensor?
Yes. The sensor can be worn while bathing, showering, swimming or exercise. The sensor should not be taken below 3 feet of water (1 meter),
and should not be submerged in water for more than 30 minutes. The adhesive is designed to keep the sensor securely and comfortably in
place for up to 14 days.
How long can the sensor be worn?
The disposable sensor is designed to adhere to the back of the upper arm and provide accurate glucose readings for up to 14 days after the
warm up period. After the 14 days, the user removes the sensor by peeling off the adhesive pad.
How do you remove the sensor?
Pull up the edge of the adhesive that keeps the sensor attached to the skin. Slowly peel away from the skin in one motion.
Note: Any remaining adhesive residue on the skin can be removed with warm soapy water or isopropyl alcohol.
What if the user needs to remove the sensor before 14 days (or if it falls off)?
Users should remove the sensor and start a new sensor. The reader will identify that it is a new sensor and ask users if they want to start it.
If a sensor falls off before 14 days have completed, then the user should call Customer Service at 1-855-632-8658.
ALARMS
Does the FreeStyle Libre 2 system have alarms?
Yes, the FreeStyle Libre 2 system has optional, real-time glucose alarms.
*Notifications will only be received when alarms are turned on and the sensor is within 20 feet of the reading device. References: 1. Haak, Thomas, et al. Flash glucose-sensing technology as a replacement for blood glucose
