The FreeStyle Libre and FreeStyle Libre 14 day Flash Glucose Monitoring Systems are continuous glucose monitoring (CGM) devices indicated for the management of diabetes in persons age 18 and older. They are designed to replace blood glucose testing for diabetes treatment decisions.
Each System detects trends and track patterns aiding in the detection of episodes of hyperglycemia and hypoglycemia, facilitating both acute and long-term therapy adjustments. Interpretation of the Sensor glucose readings should be based on the glucose trends and several sequential readings over time. The Systems are intended for single patient use and require a prescription.
You can use the System if you’re 18 or older.
The System can replace blood glucose testing except in a few situations. These are the times when you need to do a blood glucose test before deciding what to do or what treatment decision to make as Sensor readings may not accurately reflect blood glucose levels:
Do a blood glucose test if you see the Check Blood Glucose symbol. The
symbol means your Sensor glucose reading may not be accurate. For example, there may be
times when you get a low glucose reading but you do not actually have low glucose.
Do a blood glucose test if you think your glucose readings are not correct or do not match how you feel. Do not ignore symptoms that may be due to low or high glucose.
Note: The symbol will NOT appear in this situation.
MRI/CT/Diathermy: The 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.
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.

Here are some example scenarios to help you understand how to use the information on your screen. If you are not sure about what to do, consult your health care professional.
What you see - When you wake-up
What it means
When you wake up, your current glucose is 65 mg/dL and the trend arrow shows it is
changing slowly . There is also a
message at the top of the screen and the
symbol.
Anytime you see the symbol, you should do a blood glucose test before deciding
what to do.
What you see - Before breakfast
What it means
Before breakfast, your current glucose is 115 mg/dL. The graph shows that your
glucose is going up and so does the trend arrow .
Consider what might be causing your glucose to go up and what you might do to prevent a high glucose. For example:
What you see - After breakfast
What it means
After breakfast, your current glucose is 108 mg/dL. The trend arrow shows it is going
down quickly . There is also a
message at the top of the screen and the
symbol.
Anytime you see the symbol, you should do a blood glucose test before deciding
what to do.
What you see - Before lunch
What it means
When you checked your glucose before lunch, it was 90 mg/dL and rising. Before eating
lunch, you took enough insulin to cover the meal and a little more since your trend
arrow was .
What you see - After lunch
What it means
90 minutes later, your current glucose is 225 mg/dL. The graph shows that your
glucose is still going up, and so does the trend arrow .
Don’t take a correction dose within 2 hours of your meal dose. This may result in “insulin stacking” and low glucose.
Consider what might be causing your glucose to go up and what you might do to prevent a high glucose. For example:
What you see - After exercising
What it means
After exercising, you are feeling shaky, sweaty, and dizzy – symptoms you generally get when you have low glucose. But, your current glucose is 204 mg/dL.
Anytime you get a reading that doesn’t match how you feel, do a blood glucose test.
Note: The Check Blood Glucose symbol will NOT appear in this
situation.
What you see - Before dinner
What it means
Before dinner, your current glucose is 134 mg/dL. The graph shows that your
glucose is going down and so does the trend arrow .
Consider what might be causing your glucose to go down and what you might do to prevent a low glucose. For example:
What you see - After dinner
What it means
After dinner, your current glucose is 215 mg/dL but there is no trend arrow.
There is also the symbol on the screen.
Anytime you see the symbol, you should do a blood glucose test before deciding
what to do.
