Important Safety Information
Indications for Use
The FreeStyle Libre Pro Flash Glucose Monitoring System is a professional
continuous glucose monitoring (CGM) device indicated for detecting trends
and tracking patterns in persons (age 18 and older) with diabetes. The System
is intended for use by health care professionals and requires a prescription.
Readings from the FreeStyle Libre Pro Sensor are only made available to
patients through consultation with a health care professional. The System
does not require user calibration with blood glucose values.
The FreeStyle Libre Pro System aids in the detection of glucose level
excursions above or below the desired range, facilitating therapy adjustments.
Interpretation of the FreeStyle Libre Pro Flash Glucose Monitoring System
readings should be based on the trends and patterns analyzed through time
using the reports available.
IMPORTANT: The device may inaccurately indicate hypoglycemia.
The results of the clinical study conducted for this device
showed that 40% of the time when the device indicated that
user sensor glucose values were at or below 60 mg/dL, user
glucose values were actually in the range of 81-160 mg/dL.
Therefore, interpretation of the FreeStyle Libre Pro Flash Glucose
Monitoring System readings should only be based on the trends
and patterns analyzed through time using the reports available
per the intended use.
Contraindications
The FreeStyle Libre Pro Flash Glucose Monitoring System
must be removed prior to Magnetic Resonance Imaging (MRI),
Computed Tomography (CT) scan, or high-frequency electrical
heat (diathermy) treatment. The eect of MRI, CT scans, or
diathermy 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 the user’s glucose values during
the wear period.
WARNING: The FreeStyle Libre Pro Flash Glucose Monitoring
System contains small parts that may be dangerous if
swallowed.
CAUTIO N:
• Performance of the System when used with other implanted
medical devices, such as pacemakers, has not been evaluated.
• Some individuals may be sensitive to the adhesive that
keeps the Sensor attached to the skin. If your patient notices
signicant skin irritation around or under their Sensor, they
should remove the Sensor and stop using the FreeStyle Libre
Pro System. Follow your facility’s procedures for handling
skin reactions.

ART26944_rev-C_manual.indd 2-3 9/23/16 9:19 AM
Warnings/Limitations
• Review all product information before use.
• Physiologic dierences between the interstitial uid and capillary blood
may result in dierences in glucose readings. Dierences in glucose
readings between interstitial uid and capillary blood may be observed
during times of rapid change in blood glucose, such as after eating,
dosing insulin, or exercising.
• Severe dehydration and excessive water loss may cause inaccurate
results.
• Do not reuse Sensors. The Sensor and Sensor Applicator are designed
for single use. Reuse may result in no glucose readings and infection.
Not suitable for re-sterilization. Further exposure to irradiation may
cause inaccurate results.
• Interfering Substances: Taking ascorbic acid (vitamin C) while wearing
the Sensor may falsely raise Sensor glucose readings. Taking salicylic
acid (used in some pain relievers such as aspirin and some skin care
products) may slightly lower Sensor glucose readings. The level of
inaccuracy depends on the amount of the interfering substance active
in the body. Test results did not indicate interference for methyldopa
(used in some drugs to treat high blood pressure) or tolbutamide
(infrequently used in some drugs to treat diabetes in the US) at
maximum circulating levels. However, concentrations of potential
interferents in interstitial uid are unknown compared to circulating
blood. Taking medications with acetaminophen (such as Tylenol and
some cold medicines) while wearing the Sensor may falsely raise
Sensor glucose readings. The level of inaccuracy depends on the
amount of acetaminophen active in the body and may be dierent for
each person.
• Take standard precautions for transmission of blood borne pathogens
to avoid contamination.
• The Reader should be cleaned between patients.
• If a Sensor breaks inside a patient, remove with tweezers, treat any
medical complications and call Customer Service.
• Use of the System is not recommended in the critically ill population
since performance is unknown due to dierent conditions and
medications.
• Sensor placement is not approved for sites other than the back of the
arm. If placed in other areas, the Sensor may not function properly.
• If the Sensor Kit package or contents or the Reader appear to be
damaged, do not use as there may be a risk of electric shock, no results,
and/or infection.
• Store the Sensor Kit between 39°F-77°F. While you don’t need to keep
the Sensor Kit in a refrigerator, you can as long as the refrigerator is
between 39°F-77°F.
• Store the Sensor Kit between 10-90% non-condensing humidity.
• The System does not provide real-time results. Patients need to rely on
blood glucose readings for monitoring glucose during System use.
• Clean hands prior to Sensor handling/insertion to help prevent
infection.
4 5
ART26944_rev-C_manual.indd 4-5 9/23/16 9:19 AM
• Clean the application site and ensure that it is dry prior to Sensor
insertion. This helps the Sensor stay attached to the body.
• Change the application site for the next Sensor application to prevent
discomfort or skin irritation.
• Select an appropriate Sensor site to help the Sensor stay attached to the
body and prevent discomfort or skin irritation. Avoid areas with scars,
moles, stretch marks, or lumps. Select an area of skin that generally stays
at during normal daily activities (no bending or folding). Choose a site
that is at least 1 inch away from an insulin injection site.
• The Sensor should not be worn more than 14 days. Readings are not
obtained after 14 days.
• The Sensor should be removed prior to exposing it to an X-ray machine.
The eect 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 the
user’s glucose values during the wear period.
• The FreeStyle Libre Pro Flash Glucose Monitoring System has not been
evaluated for use in pregnant women, persons on dialysis, or people less
than 18 years of age.
Getting to Know the System
