Interfering Substances

Taking ascorbic acid (vitamin C) supplements while wearing the Sensor
may falsely raise Sensor glucose readings . 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 . See your health care professional to
understand how long ascorbic acid is active in your body .

Getting to Know Your System

The FreeStyle Libre 2 Flash Glucose Monitoring System ("System") has
two main parts: a handheld Reader and a disposable Sensor that you
wear on your body . You use the Reader to wirelessly scan the Sensor and
display your glucose readings . The Reader only works with FreeStyle Libre
2 Sensors and cannot be used with other Sensors . The FreeStyle Libre 2
Sensor automatically communicates with the Reader and can give you
glucose alarms if you choose to turn those on . The Reader also has a built-
in meter for blood glucose and ketone testing .
IMPORTANT: Safety information about the
System is in this User's Manual . Read all of
the information in the User's Manual and the
FreeStyle Optium blood glucose and ketone
test strip instructions for use before using your
System .
Your System comes in a Reader Kit and a Sensor Kit . When opening your
kits, check that the contents are undamaged and that you have all parts
listed . If any parts are missing or damaged, contact Customer Service .
