WARNING
Do: Store sensor between 36° F-77° F during its shelf life.
Why: Storing the sensor incorrectly might cause the sensor glucose readings to
be inaccurate.
Never store sensors in the freezer.
Consequences: If stored outside of 36° F-77° F, your sensor glucose readings may not be
accurate, resulting in you missing a severe low or high glucose event.
WARNING
Don’t: Never use the Dexcom G5 Mobile CGM System sensor glucose readings for
treatment decisions.
Do: Only use BG values from your BG meter for treatment decisions (e.g., how much
insulin to take).
Why: Since they measure your glucose from different body fluids, sensor glucose readings
can be different from your meter’s blood glucose values.
Consequences: Using sensor glucose readings for treatment decisions could result in you
missing a severe low or high event.
PRECAUTION
Do: Select sensor insertion site with care.
Avoid:
• Areas likely to be bumped, pushed or squeezed
• Areas of skin with scarring, tattoos, or irritation
• Injecting insulin within 3 inches of sensor
• Placing an insulin pump infusion set within 3 inches of sensor
Why: Inserting sensor in these areas may affect sensor glucose readings.
Consequences: Inaccurate sensor glucose readings may result in you missing a severe
low or high event.
