Warnings
Read product instructions before you use your Dexcom G7 CGM System
Don't ignore low/high symptoms: Use your BG meter to make treatment decisions
when your sensor readings don't match your low/high symptoms. If needed, seek
immediate medical attention.
No number, no arrow, no CGM treatment decision: Use your BG meter to make
treatment decisions when your Dexcom G7 CGM System doesn't show both a number
and trend arrow as well as during the 30-minute sensor warmup period.
Don't use if you are on dialysis, or critically ill: The Dexcom G7 CGM System
performance hasn't been evaluated in these populations and sensor readings may be
inaccurate.
Sensor wire breaks off: Don't ignore broken or detached sensor wires. If this
happens, please contact 24/7 technical support (in the app, go to Profile > Contact).
If a sensor wire breaks off or detaches under your skin and you can't see it, don't try to
remove it. Contact your healthcare provider if you have symptoms of infection or
inflammation — redness, swelling, or pain — at the insertion site.
Where to insert — arm or buttocks: Don't wear it on other sites as it may not work
as expected. If you wore G6 sensors on your abdomen, wear G7 sensors on the back
of your upper arm. Children from 2 to 6 years old can also choose their upper
buttocks.
Where to store: You can store your sensors at room temperature or in your
refrigerator, between 36° F and 86° F, but not in the freezer.
Inspect: Don't use any damaged or cracked Dexcom G7 CGM System component
because it may not work correctly and could cause injuries from electrical shocks.
Use as directed: The Dexcom G7 CGM System is small and may pose a choking
hazard if swallowed.

Questions and answers
Dexcom G7 continues to show readings 50 or 60 points higher than when I stick my finger and use the supplied recorder. Why?
The Dexcom G7 may show readings 50 or 60 points higher than fingerstick measurements due to several reasons:
1. Sensor's First Day: Newly inserted sensors may show larger differences, which usually decrease over the first 24 hours.
2. Pressure on Sensor: If something is pressing on the sensor (e.g., lying on it), it can affect readings. Removing the pressure can help.
3. Rapid Glucose Changes: Blood glucose changes before interstitial fluid glucose, so fast changes can cause differences between meter and sensor readings.
4. Fingerstick Issues: Inaccurate fingerstick readings can occur if hands are not washed properly or test strips are expired or used incorrectly.
These factors can cause temporary differences between Dexcom G7 and fingerstick readings.
