  2. What Is CGM?

Easy monitoring*†1,2 with continuous
data collection3-5

 

Make treatment decisions anytime, high or low, no fingersticks​​​​​​​​§ǁ required

CGM systems, like the FreeStyle Libre portfolio of products, provide easy visibility to hidden problems¶6  with up to 14 days of glucose readings on your patients’ smartphones#**. With optional, real-time glucose alarms††‡‡, rest assured your patients will know when they’re high or low.

CGM = continuous glucose monitoring

For people with diabetes, missing a clear connection between glycemic control and diabetes management behaviors can result in7:

Not meeting their A1c goals

Not regularly monitoring their
glucose levels

Not making diet and exercise
changes as needed

A1c alone8 does not fully reveal glycemic patterns and trends

 

  Above Target Range (>180 mg/dL)      In Target Range (70-180 mg/dL)     Below Target Range (<70 mg/dL)

For illustrative purposes only. Not actual patient data. 
Sensor is water-resistant in up to 1 meter (3 feet) of water. Do not immerse longer than 30 minutes.

FreeStyle Libre CGM systems reveal a complete picture¶6 without the pain and hassle of fingersticks*†§ǁ1

For patients with Type 2 diabetes using blood glucose monitoring (BGM), highs and lows aren't always easy to see¶6 .

For illustrative purposes only. Not actual patient data.

The use of fingerstick testing9 or A1c alone8 do not fully reveal glycemic patterns and trends,
but with FreeStyle Libre CGM systems, hidden glucose patterns are uncovered¶6.

Who can benefit from the FreeStyle Libre CGM systems?

  • FreeStyle Libre 2 and 3 systems provide unsurpassed 14-day accuracy3,4 for adults and children and are proven to help children and teens§§ achieve better glycemic control vs BGM*†IIII10

  • FreeStyle Libre CGM systems have been observed to reduce A1c similar to a diabetes oral medication¶11,12

Medicare coverage is available for the FreeStyle Libre 2 system if the FreeStyle Libre 2 reader is used to review glucose data on some days every month. Medicare and other third party payor criteria apply.

At this time, FreeStyle Libre 3 is not currently eligible for Medicare reimbursement, and Medicaid eligibility may vary by state.

‡ Glucose readings are not available during 1-hour warm-up, when sensor is too hot or too cold, when you see an error or “LO” or “HI” message, or no current glucose reading.

§ FreeStyle Libre 2 and 3 systems: Fingersticks are required if your glucose alarms and readings do not match symptoms or when you see Check Blood Glucose symbol during the first 12 hours.

ǁ FreeStyle Libre 14 day system: 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.

Important Safety Information

FreeStyle Libre 14 day system: Failure to use FreeStyle Libre 14 day system as instructed in labeling may result in missing a severe low or high glucose event and/or making a treatment decision, resulting in injury. If readings do not match symptoms or expectations, use a fingerstick value from a blood glucose meter for treatment decisions. Seek medical attention when appropriate or contact Abbott at 855-632-8658 or FreeStyleLibre.us for safety info.

FreeStyle Libre 2 and FreeStyle Libre 3 systems: Failure to use FreeStyle Libre 2 or FreeStyle Libre 3 systems as instructed in labeling may result in missing a severe low or high glucose event and/or making a treatment decision, resulting in injury. If glucose alarms and readings do not match symptoms or expectations, use a fingerstick value from a blood glucose meter for treatment decisions. Seek medical attention when appropriate or contact Abbott at 855-632-8658 or FreeStyleLibre.us for safety info.

FreeStyle Libre Pro: The FreeStyle Libre Pro Flash Glucose Monitoring System is a professional continuous glucose monitoring (CGM) device indicated for detecting trends and tracking patterns and glucose level excursions above or below the desired range, facilitating therapy adjustments in persons (age 18 and older) with diabetes. The system is intended for use by health care professionals and requires a prescription.

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

WARNINGS/LIMITATIONS: The FreeStyle Libre Pro System does not provide real-time results and patients should adhere to their blood glucose monitoring routine while using the system. If a sensor breaks, contact physician and call Customer Service. Patients with high levels of ascorbic acid (Vitamin C) or salicylic acid (used in Aspirin) or severe dehydration or excessive water loss may experience inaccurate results with this system. The FreeStyle Libre Pro System is not approved for pregnant women, persons on dialysis, or recommended for 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. Review all product information before use or contact Abbott Toll Free (855-632-5297) (or visit provider.myfreestyle.com) for detailed indications for use and safety information.
