Safety Statement; Treatment Decisions: The Basics - Dexcom G5 MOBILE User Manual

13.2 Safety Statement

Warning
Do: Do take a BG measurement with your BG meter and use the BG value for treatment
decisions (such as how much insulin to take) if your Dexcom G5 does not display both a
number and a trend arrow.
Why: Not having both a number and the arrow means you may be getting inconsistent
or inaccurate sensor glucose readings.
Consequences: Using inconsistent or inaccurate sensor glucose readings for
treatment decisions could result in you missing a severe low or high blood glucose
event or making a treatment decision that results in injury.

13.3 Treatment Decisions: The Basics

How Do You Know You're Ready?
Whether you're new to Dexcom or experienced, you should keep using your BG meter
to make treatment decisions until you know how Dexcom works for you. Don't rush!
It may take days, weeks or months for you to gain confidence in using your CGM to make
treatment decisions. Confirm your glucose readings using your BG meter so you
understand that:
• The accuracy you experience with each newly inserted sensor may vary
• A sensor might work differently in different situations (meals, exercise, first day of
use, etc.)
Before you start making treatment decisions with your Dexcom G5, work with your HCP and
learn the basics: When do you need to use a BG meter instead of relying on your Dexcom G5?
How can you avoid insulin stacking? Once you and your HCP are comfortable that you know
the basics, you're ready!
Some users have reported that performance may vary significantly between sensors; pay
attention to how each newly inserted sensor is working for you when deciding whether to
make treatment decisions based on your glucose readings. If your symptoms don't match
your glucose readings, use your BG meter when making treatment decisions. If your glucose
readings don't consistently match your symptoms or BG meter values then talk to your
healthcare professional about how you should be using the Dexcom G5 to help manage your
diabetes. Your healthcare provider can help you decide how you should best use this device."
