FreeStyle Libre CGMs deliver real-time glucose data.

  • View patients’ complete glycemic profiles anytime, enabling more informed treatment decisions*7.
  • Patients can respond faster to glucose changes, helping to avoid hypoglycemia.
  • Significantly lowers A1C*6,§8 without fingersticksǁ.

See the full picture3 without the pain and hassle of fingersticksǁ.

CGM provides a more complete picture of where a patient's glucose is and where it is going, so they can make more informed decisions.

BGM measures a single point in time.

CGM provides glucose readings every minute.

For illustrative purposes only. Not actual patient data.

BGM = blood glucose monitor(ing)

Increase in time in range can help your patients improve A1C9.

A1C provides a broad snapshot reflecting average glucose over 2–3 months9,10.

Time in range (TIR) is the percentage of time your patient spends in a pre-set glucose target range9.

  • TIR report includes time above range, time in target range, and time below range11,12.
  • TIR offers context for A1C by allowing you to quickly assess the patient’s glucose control.

* Study was performed with the outside US version of the FreeStyle Libre 14 day system. Data is applicable to FreeStyle Libre 2 and FreeStyle Libre 3 systems, as feature sets are similar as FreeStyle Libre 14 day system, excluding alarms.

† The 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.

‡ 60-minute warm-up required when starting the sensor.

§ Study was performed with the outside US version of the FreeStyle Libre 2 system. Data is applicable to FreeStyle Libre 3 system, as feature sets are similar.

ǁ Fingersticks are required if your glucose alarms and readings do not match symptoms or when you see Check Blood Glucose symbol during the first twelve hours.

¶ Study was performed with the US version of the FreeStyle Libre 14 day system. Data is applicable to FreeStyle Libre 2 and FreeStyle Libre 3 systems, as feature sets are similar as FreeStyle Libre 14 day system, excluding alarms.

# Observational study with mean A1C levels of 10.1% at baseline.

** REPLACE trial: a randomized, controlled trial to evaluate the impact of FreeStyle Libre glucose monitoring system (n=149) on HbA1c in people with type 2 diabetes (T2D) taking multiple daily doses of insulin at 6 months compared to blood glucose monitoring (BGM;n=75).

Important Safety Information

Failure to use FreeStyle Libre 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 reading and alarms (if enabled) do not match symptoms or expectations, use a fingerstick value from a blood glucose meter for treatment decisions. Get medical attention when appropriate. Abbott Customer Service at 855-632-8658 or visit FreeStyleLibre.us for safety info.
