Limited Warranty Information

We hope that you are fully satisfied with the FreeStyle Libre 14 day system. Limited Warranty: Abbott Diabetes Care (“Abbott”) warrants that the FreeStyle Libre 14 day reader (“Reader”) shall be free from defects in material and workmanship for a period of one (1) year from the date of manufacture or one (1) year from the original date of purchase with proof of purchase (whichever is later). This Limited Warranty is invalid if the Reader is modified, altered, damaged, misused or used other than in accordance with the User’s Manual, applicable labeling, and/or inserts. Abbott’s sole obligation is to replace the Reader, free of charge, with the same or an alternative reader as determined by Abbott in its sole discretion. Your replacement may be a different model or type. Abbott may require, as a condition of obtaining limited warranty service, that you return the Reader postage prepaid, with proof of purchase to an address specified by Abbott. The Limited Warranty on the replacement Reader will expire on the date of the original Limited Warranty expiration or 90 days after the shipment of a replacement Reader, whichever period is longer. This Limited Warranty covers only the Reader, does not cover the sensor or disposable accessories, extends only to the original purchaser, and is not assignable or transferable, and states your exclusive remedy. TO THE EXTENT POSSIBLE UNDER LAW, THE FOREGOING ARE ABBOTT’S ONLY WARRANTIES FOR THE READER AND STATE YOUR EXCLUSIVE REMEDY. ABBOTT MAKES NO OTHER WARRANTIES, EXPRESS OR IMPLIED, AND ABBOTT EXCLUDES AND DISCLAIMS ANY OTHER WARRANTIES INCLUDING, BUT NOT LIMITED TO, IMPLIED WARRANTIES OF MERCHANTABILITY, NONINFRINGEMENT, AND FITNESS FOR A PARTICULAR PURPOSE. ABBOTT DOES NOT WARRANT THAT OPERATION OF THE READER WILL BE UNINTERRUPTED OR ERROR FREE AND ABBOTT WILL NOT BE LIABLE FOR ANY LOST PROFITS, LOST SAVINGS OR OTHER SPECIAL, PUNITIVE, INCIDENTAL OR CONSEQUENTIAL DAMAGES RESULTING DIRECTLY OR INDIRECTLY FROM PURCHASE, OPERATION OR USE OF THE READER OR FAILURE OF THE READER TO PERFORM IN ACCORDANCE WITH SPECIFICATIONS, REGARDLESS OF THE LEGAL THEORY ON WHICH THE CLAIM IS BASED, AND EVEN IF ABBOTT HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. NO WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, IF ANY IS IMPLIED FROM THE SALE OF THE READER DESPITE ABBOTT’S SPECIFIC DISCLAIMER OF SUCH WARRANTIES, SHALL EXTEND FOR A LONGER DURATION THAN ONE YEAR FROM THE ORIGINAL DATE OF PURCHASE OF THE READER. NO WARRANTY OR GUARANTEE GIVEN BY ANY PERSON, FIRM, OR CORPORATION WITH RESPECT TO THE READER OR THE SENSOR SHALL BE BINDING ON ABBOTT. This Limited Warranty and any dispute or claim arising out of or in connection with it shall be governed by and construed in accordance with the laws of Delaware. Some states do not allow limitations on how long an implied warranty lasts or the exclusion or limitation of incidental or consequential damages, so the above limitations or exclusions may not apply to you. Your Rights Under State Law: This Limited Warranty gives you specific legal rights, and you may also have other rights that vary from state to state.


To the extent allowed by law, the FreeStyle Libre sensor is provided to you “as is.” Abbott hereby disclaims all warranties (express, implied, and statutory) with respect to the sensor, including, but not limited to, the implied warranties of merchantability and fitness for a particular purpose. There are no warranties which extend beyond the description on the face hereof.

Indications and Important Safety Information

FreeStyle Libre 14 day system: FreeStyle Libre 14 day Flash Glucose Monitoring systems are continuous glucose monitoring (CGM) devices indicated for replacing blood glucose testing and detecting trends and tracking patterns aiding in the detection of episodes of hyperglycemia and hypoglycemia, facilitating both acute and long-term therapy adjustments in persons (age 18 and older) with diabetes. The systems are intended for single patient use and require 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 system does not have alarms unless the sensor is scanned, and the system contains small parts that may be dangerous if swallowed. The 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.

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.
