Warnings outline important hazard information, describing any serious and/or
life-threatening situations, their consequences, how to avoid danger while
using the system and how to protect the G5x from harm.
Review Training Materials
Thoroughly review the training materials included with your system before
using.
Incorrect use could lead you to misunderstand system information or might
affect its performance and you might miss a severe low or high glucose event.
Treatment Decisions
The system does not replace your BG meter.
When making treatment decisions, such as the amount of insulin you need,
only use your BG value. Don’t use the G5x sensor glucose readings because
they can be different from your BG value. If sensor glucose readings are used
in determining treatments, it could result in you missing a severe low or high
glucose event.
Don’t Ignore Low/High Symptoms
If your sensor glucose readings don’t match your symptoms, measure your
BG with a fingerstick. You may miss a severe low or high glucose event.
Who Shouldn’t Use
The system was not evaluated for the following persons:
• Pregnant women
• Persons on dialysis
Do not use the Dexcom G5x System in critically ill patients. It is not known
how different conditions or medications common to the critically ill population
may affect the performance of the system. Sensor glucose readings may be
inaccurate in critically ill patients.
The system’s accuracy hasn’t been tested in people falling into these groups
and sensor glucose readings may be inaccurate, resulting in missing a severe
low or high event.
