What is it?

The FreeStyle Libre 14 day system is a continuous glucose monitoring (CGM) system consisting of a smartphone app or a handheld reader and a glucose sensor worn on the back of the upper arm.

How does it work?

The sensor uses a thin, flexible filament inserted just under the skin to measure glucose levels every minute.

How do you use it?

Use your smartphone or handheld reader to scan the glucose sensor with a painless,1 one-second scan to replace fingersticks.*

What your FreeStyle Libre 14 day reader can show you

Sensor Glucose Readings

The Sensor Glucose Readings screen appears after you use the reader or smartphone to scan your sensor. Your reading includes your current glucose reading, a glucose trend arrow indicating which way your glucose is headed, and a graph showing your 8 hour glucose history.

Daily Patterns

A graph showing the pattern and variability of your sensor glucose over a typical day. The thick black line shows the midpoint of your glucose readings. The gray shading represents a range of your sensor readings.

Note: Daily Patterns needs at least 5 days of glucose data.

Low Glucose Events

This view provides information about the number of low glucose events measured by your sensor. The total number of events is displayed above the graph. The bar graph displays the low glucose events in four different 6-hour periods of the day. Use the arrows to view your glucose data collected over the last 7, 14, 30, or 90 days. Low glucose events are recorded when glucose readings are lower than 70 mg/dL for longer than 15 minutes.

Time In Target

Shows the percentage of time your sensor readings were above, below, and within your target glucose range.**

Visual Alerts

If your glucose reading is rapidly changing, below 70 mg/dL or projected to be below 70 mg/dL, or if there is no glucose number or trend arrow, you will see a visual alert, the Check Blood Glucose symbol. When you see this symbol, do a blood glucose test before making treatment decisions.

*Fingersticks are required for treatment decisions when you see Check Blood Glucose symbol, when symptoms do not match system readings, when you suspect readings may be inaccurate, or when you experience symptoms that may be due to high or low blood glucose.

Data based on the number of users worldwide for FreeStyle Libre family of personal CGMs compared to the number of users for other leading personal CGM brands and based on CGM sales dollars compared to other leading personal CGM brands.

The FreeStyle LibreLink app is only compatible with certain mobile devices and operating systems. Please check our compatibility guide for more information about device compatibility before using the app. Use of the FreeStyle LibreLink app requires registration with LibreView.

§The reader can capture data from the sensor when it is within 1 cm to 4 cm of the sensor.

ǁThe LibreView data management software is intended for use by both patients and healthcare professionals to assist people with diabetes and their healthcare professionals in the review, analysis and evaluation of historical glucose meter data to support effective diabetes management. The LibreView software is not intended to provide treatment decisions or to be used as a substitute for professional healthcare advice.

Sensor is water-resistant in up to 1 meter (3 feet) of water. Do not immerse longer than 30 minutes.

#Based on the sensor being replaced once every 14 days, and scanned at least once every 8 hours.

**Default range is 70-180 mg/dL. Consult with a healthcare professional on individual target glucose range.

††Choose a site that is at least 2.5 cm (1 inch) away from an insulin injection site.

‡‡CAUTION: The Sensor Pack and Sensor Applicator have the same sensor code. The sensor codes should be checked to ensure they match before using Sensor Pack and Sensor Applicator. Do not use Sensor Packs and Sensor Applicators with different Sensor codes together as this will result in incorrect glucose readings.

§§Do NOT use if the Sensor Pack or the Sensor Applicator seem to be damaged or already opened. Do NOT use if past expiration date.

ǁǁThe Sensor Applicator contains a needle. Do not touch inside the Sensor Applicator or put it back into the Sensor Pack.

¶¶Do not push down on the Sensor Applicator until placed over prepared site to prevent unintended results or injury.

##Applying the Sensor may cause bruising or bleeding. If there is bleeding that does not stop, remove the Sensor, and apply a new one at a different site.

Indications and Important Safety Information

FreeStyle Libre 14 day system: The FreeStyle Libre 14 day Flash Glucose Monitoring System is a continuous glucose monitoring (CGM) device indicated for the management of diabetes in persons age 18 and older. It is designed to replace blood glucose testing for diabetes treatment decisions. The System detects trends and tracks patterns aiding in the detection of episodes of hyperglycemia and hypoglycemia, facilitating both acute and long-term therapy adjustments. Interpretation of the System readings should be based on the glucose trends and several sequential readings over time. The System is intended for single patient use and requires a prescription.

CONTRAINDICATIONS: Remove the sensor before MRI, CT scan, X-ray, or diathermy treatment.

WARNINGS/LIMITATIONS: Do not ignore symptoms that may be due to low or high blood glucose, hypoglycemic unawareness, or dehydration. Check sensor glucose readings with a blood glucose meter when Check Blood Glucose symbol appears, when symptoms do not match system readings, or when readings are suspected to be inaccurate. The FreeStyle Libre 14 day system does not have alarms unless the sensor is scanned, and the system contains small parts that may be dangerous if swallowed. The FreeStyle Libre 14 day system is not approved for pregnant women, persons on dialysis, or critically-ill population. Sensor placement is not approved for sites other than the back of the arm and standard precautions for transmission of blood borne pathogens should be taken. The built-in blood glucose meter is not for use on dehydrated, hypotensive, in shock, hyperglycemic-hyperosmolar state, with or without ketosis, neonates, critically-ill patients, or for diagnosis or screening of diabetes. When using FreeStyle LibreLink app, access to a blood glucose monitoring system is required as the app does not provide one. Review all product information before use or contact Abbott Toll Free (855-632-8658) (or visit www.freestylelibre.us) for detailed indications for use and safety information. For full indications for use and safety information, see more here.

FreeStyle Libre 2 system: The FreeStyle Libre 2 Flash Glucose Monitoring System is a continuous glucose monitoring (CGM) device with real time alarms capability indicated for the management of diabetes in persons age 4 and older.*

WARNINGS/LIMITATIONS*: The System must not be used with automated insulin dosing (AID) systems, including closed loop and insulin suspend systems. Remove the sensor before MRI, CT scan, X-ray, or diathermy treatment. Do not take high doses of vitamin C (more than 500 mg per day), as this may falsely raise your Sensor readings. Failure to use the System according to the instructions for use may result in missing a severe low blood glucose or high blood glucose event and/or making a treatment decision that may result in injury. If glucose alarms and readings from the System do not match symptoms or expectations, use a fingerstick blood glucose value to make diabetes treatment decisions. Seek medical attention when appropriate and contact Abbott Toll Free (855-632-8658) or visit * www.freestylelibre.us for detailed indications for use and safety information.

*Please refer to www.freestylelibre.us for the indications and important safety information.
