Important Safety
Information
capillary blood may be observed during times of rapid change in blood glucose, such as after eating, dosing insulin, or exercising.
What to know about X-Rays:
•
The Sensor should be removed prior to exposing it to an X-ray machine. The effect of X-rays on the performance of the System has not
been evaluated. The exposure may damage the Sensor and may impact proper function of the device to detect trends and track patterns
in glucose values during the wear period.
When to remove 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 readings, which may
not match how you feel. Check to make sure your Sensor has not come loose. If it has come loose, remove it, apply a new one, and contact
Customer Service.
•
If you believe your glucose readings are not correct or are inconsistent with how you feel, perform a blood glucose test on your finger to
confirm your glucose. If the problem continues, remove the current Sensor, apply a new one, and contact Customer Service. Customer
Service is available at 1-855-632-8658 7 Days a Week from 8AM to 8PM Eastern Standard Time.
What to know about the Reader’s Built-in Meter:
•
The FreeStyle Libre 2 Reader has a built-in blood glucose meter that is designed to be used only with FreeStyle Precision Neo blood
glucose test strips and MediSense Glucose and Ketone Control Solution. Using other test strips with the Reader’s built-in meter will
produce an error or cause the Reader’s built-in meter to not turn on or start a test. The Reader’s built-in meter does not have ketone
testing functionality.
•
The Reader’s built-in meter is not for use on people who are dehydrated, hypotensive, in shock, or for individuals in hyperglycemic-
hyperosmolar state, with or without ketosis.
•
The Reader’s built-in meter is not for use on neonates, in critically-ill patients, or for diagnosis or screening of diabetes.
•
See
Using the
Reader’s Built-in meter
section for additional important information on the use of the Reader’s built-in meter.
Where to charge your Reader:
•
Be sure to select a location for charging that allows the power adapter to be easily unplugged. Do NOT block access to the charger due
to the potential risk of electrical shock.
Interfering Substances
Interfering Substances
Taking ascorbic acid (vitamin C) supplements while wearing the Sensor may falsely raise Sensor glucose readings. You can take doses of ascorbic
acid up to 500 mg per day and make treatment decisions with the Sensor. Taking more than 500 mg of ascorbic acid per day may affect the
Sensor readings which could cause you to miss a severe low glucose event. Ascorbic acid can be found in supplements including multivitamins.
Some supplements, including cold remedies such as Airborne® and Emergen-C®, may contain high doses of 1000 mg of ascorbic acid and should
not be taken while using the Sensor. See your health care professional to understand how long ascorbic acid is active in your body.
