FULL INDICATIONS AND IMPORTANT SAFETY INFORMATION
FREESTYLE LIBRE 14 DAY

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:

The FreeStyle Libre 14 day 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 effect 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 which could cause incorrect readings.

WARNINGS:

• Do not ignore symptoms that may be due to low or high blood glucose: If you are experiencing symptoms that are not consistent with your glucose readings, consult your healthcare professional.
• Check Sensor glucose readings by conducting a fingerstick test with a blood glucose meter under the following conditions, when Sensor glucose readings may not be accurate and should not be used to make a diabetes treatment decision:
  • If you suspect that your reading may be inaccurate for any reason
  • When you are experiencing symptoms that may be due to low or high blood glucose
  • When you are experiencing symptoms that do not match the Sensor glucose readings
  • During the first 12 hours of wearing a FreeStyle Libre 14 day Sensor
  • During times of rapidly changing glucose (more than 2 mg/dL per minute)
  • When the Sensor glucose reading does not include a Current Glucose number or Glucose Trend Arrow
  • In order to confirm hypoglycemia or impending hypoglycemia as reported by the Sensor
• When you see the Check Blood Glucose symbol, you must check your blood glucose with a blood glucose meter before making any treatment decisions. Sensor readings may not accurately reflect blood glucose levels.
• Hypoglycemic unawareness: The System has not been evaluated for use in patients with hypoglycemic unawareness and will not automatically alert you of a hypoglycemic event without you scanning your Sensor.
• No alarms without a Sensor scan: The System does not have alarms that will automatically notify you when you are having a severe low (hypoglycemic) or high (hyperglycemic) glucose event unless you scan your Sensor. For example, the System does not have an alarm that can alert or wake you when you are sleeping in the case of low or high glucose.
• Choking hazard: The FreeStyle Libre 14 day system contains small parts that may be dangerous if swallowed.

CAUTIONS AND LIMITATIONS:

Below are important cautions and limitations to keep in mind so you can use the System safely. They are grouped into categories for easy reference.

What to know about Alarms/Alerts:

• There are NO alarms or alerts unless you scan the Sensor.

What to know before using the System:

• Review all product information before use.
• Take standard precautions for transmission of blood borne pathogens to avoid contamination.

Who should not use the System:

• Do not use the System in people less than 18 years of age. The System is not approved for use in people under 18 years of age and Sensor readings in this population may be inaccurate. In general, continuous glucose monitoring systems are recognized to be less accurate in children than in adults.
• Do not use the System in critically ill patients. The System is not approved for use in these patients. It is not known how different conditions or medications common to the critically ill population may affect performance of the System. Sensor glucose readings may be inaccurate in critically ill patients.
• Do not use the System in pregnant women or persons on dialysis. The System is not approved for use in pregnant women or persons on dialysis and has not been evaluated in these populations.
• Performance of the System when used with other implanted medical devices, such as pacemakers, has not been evaluated.

What should you know about wearing a Sensor:

• The Sensor can be worn for up to 14 days.
• Some individuals may be sensitive to the adhesive that keeps the Sensor attached to the skin. If you notice significant skin irritation around or under your Sensor, remove the Sensor and stop using the System. Contact your healthcare professional before continuing to use the System.
• Intense exercise may cause your Sensor to loosen due to sweat or movement of the Sensor. Remove and replace your Sensor if it starts to loosen and follow the instructions to select an appropriate application site.
• The System uses all available glucose data to give you readings so you should scan your Sensor at least once every 8 hours for the most accurate performance. Scanning less frequently may result in decreased performance.
• 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.
• If a Sensor breaks inside your body, call your healthcare professional.

How to Store the Sensor Kit:

• Store the Sensor Kit between 39°F and 77°F. Storage outside of this range may cause inaccurate Sensor glucose readings. While you don’t need to keep your Sensor Kit in a refrigerator, you can as long as the refrigerator is between 39°F and 77°F. Do not freeze.
• Store the Sensor Kit between 10-90% non-condensing humidity.

When not to use the System:

• Do NOT use if the Sensor Kit package, Sensor Pack, or Sensor Applicator appear to be damaged or already opened due to risk of no results and/or infection.
• Do NOT use if Sensor Kit contents are past expiration date.
• Do NOT use if the Reader appears to be damaged due to risk of electric shock and/or no results.

What to know before you Apply the Sensor:

• The Sensor Pack and Sensor Applicator are packaged as a set (separately from the Reader) and have the same Sensor code. Check that the Sensor codes match before using your 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.
• Clean the application site and ensure that it is dry prior to Sensor insertion. This helps the Sensor stay attached to your body.
• Clean hands prior to Sensor handling/insertion to help prevent infection.
• Change the application site for the next Sensor application to prevent discomfort or skin irritation.
• 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.
• 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 flat during normal daily activities (no bending or folding). Choose a site that is at least 1 inch away from an insulin injection site.

When is Sensor Glucose different from Blood Glucose:

• Physiological differences between the interstitial fluid and capillary blood may result in differences in glucose readings between the System and results from a fingerstick test using a blood glucose meter. Differences in glucose readings between interstitial fluid and 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 interfering substances such as Vitamin C and Aspirin:

• 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 fluid are unknown compared to circulating blood.

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 and apply a new one.
• 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 and apply a new one.

What to do if you are dehydrated:

• Severe dehydration and excessive water loss may cause inaccurate Sensor glucose readings. If you believe you are suffering from dehydration, consult your healthcare professional immediately.

What to know about the Reader’s Built-in Meter:

• The FreeStyle Libre 14 day 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.

• During set up, the App asks for phone permissions. Please allow these. If your phone is not set up properly, you will not be able to use the App and will not get alarms, including the Urgent Low Glucose Alarm. Confirm your settings are as follows:
  • iPhones settings:
    • In the phone settings, keep Bluetooth ON
    • In the phone settings for the App, allow the App to access Bluetooth
    • In the phone settings for the App under Notifications, keep Critical Alerts ON
  • Android Phones settings:
    • In the phone settings, keep Bluetooth ON
    • In the phone settings for the App, keep Do Not Disturb access permission ON
    • In the phone settings for the App, keep Nearby Devices permission ON (for Android 12 and above)

  Follow the instructions in the App to turn on these settings and permissions. If your phone is not configured correctly, you will see Alarms Unavailable on your screen.

  • Android users may need to add Libre app to the list of the apps that will not be restricted or put to sleep.
  • If you adjust the phone ringer volume (iPhone) or Media volume (Android) to silent or use the phone do not disturb setting, keep 'Override Do Not Disturb' setting in the App ON for Low Glucose, High Glucose, and Signal Loss Alarms to ensure you receive audible alarms.

For you to receive alarms:

• Keep your phone charged and turned on.
• Don't force close the App. The App must be running in the background to get alarms.
• Always keep your phone within 33 feet of you, with no obstacles between you. The Sensor itself will not issue alarms! If you’re out of range, you may not get alarms. If you want to use the App's optional alarms, keep these turned on.
• Disconnect headphones or speakers from your phone when not in use. You may miss alarm sounds if you don’t.
• Remember that if you have accessories connected to your phone (like wireless headphones or a smartwatch), you may get alarms on only one device, not all.

Go to the Alarms section to learn more about the App's alarms.

CAUTION – SENSOR USE

What to know before you apply the Sensor:

• Your Sensor Pack and Sensor Applicator come as a set with the same Sensor code. Check that the Sensor codes match! Don’t use Sensor Packs and Sensor Applicators with different Sensor codes together as you'll get incorrect glucose readings.
• The Sensor inserts just under your skin. You may have some bruising or bleeding.
• Clean your hands before handling the Sensor Kit contents. This will help prevent infection.
• Carefully follow the instructions to prepare the application site on the back of your upper arm. This will help your Sensor stay on for the full wear time and not fall off early. Wash the site using a plain soap. Then, dry and clean with an alcohol wipe. This removes any oily residue and helps the Sensor stick. Allow the site to air dry before applying the Sensor.
• Only apply the Sensor to the back of your upper arm. The Sensor may not work properly in other areas. Avoid scars, moles, stretch marks, and lumps. Choose an area that stays mostly flat (no bending or folding) during your day. Keep at least 1 inch away from insulin injection sites.
• Change sites between Sensors so your skin can recover.

What to know about wearing a Sensor:

• Your Sensor's product insert tells you how long you can wear your Sensor. Remember to always have your next Sensor on hand before your current one ends so you can keep getting your glucose readings.
• If your Sensor stops working and you don’t have another Sensor, use another method to check your glucose and make treatment decisions.
• The App can detect when the Sensor isn’t working properly. It will shut your Sensor off and tell you to replace it. This may happen if the Sensor gets knocked off your body, or if there’s a problem with it. Call us if you receive a Replace Sensor message before the end of your wear time. Customer Service: 1-855-632-8658. Available 7 days a week, 8 a.m. to 8 p.m. Eastern Time; excluding holidays.
• Some people may be sensitive to the adhesive that keeps the Sensor attached to the skin. If you notice significant skin irritation around or under your Sensor, remove the Sensor. Contact your health care professional before continuing to use the System.
• Intense exercise may cause your Sensor to loosen due to sweat or Sensor movement. If the Sensor gets loose or its tip comes out of your skin, you may get no readings or unreliable low readings. Remove your Sensor and apply a new one. Don’t attempt to reinsert the old one! Call us if any Sensor gets loose or falls off before the end of your wear time. Customer Service: 1-855-632-8658. Available 7 days a week, 8 a.m. to 8 p.m. Eastern Time; excluding holidays.
• Don't 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 unreliable low results.
• If a Sensor breaks in your body, call your health care professional.

How to store the Sensor Kit:

• Store between 36°F and 82°F. Storing outside this range may cause inaccurate Sensor glucose readings.
• If you think that the temperature may exceed 82°F (for example, in an un-airconditioned home in summer), you should refrigerate your Sensor Kit. Don’t freeze your Sensor Kit.
• Store in a cool, dry place. Don’t store in a parked car on a hot day.
• Store between 10-90% non-condensing humidity.

When to remove the Sensor:

• If the Sensor is becoming loose or if its tip is coming out of your skin, you may get no readings. Or, you may get unreliable readings that don’t match how you feel. Check to make sure your Sensor is not loose. If it’s loose, remove it and apply a new one. Please call Customer Service.
• If you think your glucose readings are incorrect or don’t match how you feel, do a blood glucose test on your finger to check your glucose. If the problem continues, remove the Sensor and apply a new one. Call Customer Service: 1-855-632-8658. Available 7 days a week, 8 a.m. to 8 p.m. Eastern Time; excluding holidays.

When not to use the Sensor:

• Don't use if the Sensor Kit carton, Sensor Pack, or Sensor Applicator look damaged or opened. Infection may result.
• Don't use if Sensor Kit contents have expired.
• Go to the Applying Your Sensor section to learn how to prepare and apply your Sensor.

MRI safety information:

• You can safely have a 1.5T or 3T MRI exam while wearing your Sensor, under the conditions listed below. Injury may result if the conditions are not followed. Leave your phone and Reader outside of the exam room. Sensor readings may be inaccurate during the MRI, but System function returns fully back to normal after 1 hour.

SECURITY INFORMATION:

• You are responsible for properly securing and managing your phone. If you suspect an adverse cybersecurity event related to the App, contact Customer Service.
• The App is not intended for use on a phone that has been altered or customized to remove, replace or circumvent the manufacturer’s approved configuration or use restriction, or that otherwise violates the manufacturer’s warranty.
• Don't use the App on a jailbroken or rooted device. When used on a jailbroken or rooted device or in the case of a potential cybersecurity event, the App will stop without notification. This means you won't receive alarms and will need to use another method to check your glucose. Please contact Customer Service.
• Use of an unsupported mobile device or OS version may affect App security and functionality. You are responsible for the risks associated with the use of the App on an unsupported mobile device or OS version.
• The App should only be downloaded and/or updated through authorized distributors, including the App Store (iPhone) and Google Play Store (Android).

INTERFERING SUBSTANCES

Libre 3 Sensor

Taking Vitamin C supplements while wearing the Sensor may falsely raise Sensor glucose readings. Taking more than 500 mg of Vitamin C per day may affect the Sensor readings. This could cause you to miss a severe low glucose event. Vitamin C 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 Vitamin C. These should not be taken while using the Sensor. See your health care professional to understand how long Vitamin C is active in your body.
