When In Doubt; Just Took Acetaminophen; Use A Smart Watch; No Arrows Or Readings - Dexcom G5 User Manual

If the symptoms don't match, use the BG meter. Don't ignore changes in behavior. Take a
fingerstick and treat accordingly.

When in Doubt

Sometimes you don't feel your lows or highs. Or you may be new to diabetes and aren't sure
what your body is telling you. When in doubt, use your BG meter to determine your BG value
before making treatment decisions.
Sometimes on your first day, it takes a little while for your body and sensor to know each
other. Until you are comfortable with making treatment decisions with the G5, use your
meter.

Just Took Acetaminophen

Any medications containing acetaminophen, such as Tylenol , Excedrin Extra Strength , or
® ®
Nyquil can give you a false high reading. Never use the Dexcom G5 Mobile for treatment
®
decisions if acetaminophen is in your system; always use your BG meter.

Use a Smart Watch

You shouldn't use your smart watch readings for treatment decisions.
If you're using a smart watch to get your Dexcom G5 Mobile information, look at your receiver
or smart device before making a treatment decision. Your smart watch reflects information
sent from your smart device and may not show your most recent sensor readings.

No Arrows or Readings

To make a treatment decision, you want to make sure all the information is there. Anytime
you don't have a number and arrow on your home screen, use your BG meter to get a BG
value to make treatment decisions. If your home screen shows Signal Loss or Low or High
instead of a glucose reading number, use your BG meter.
At times you may have a number but not an arrow. When this happens, use your BG meter.
No number, no arrow, don't use your Dexcom G5 Mobile for treatment decisions.
Learning what not to do isn't just about deciding if you need to use your BG meter and not
your Dexcom G5 Mobile. It's also about learning when you shouldn't dose. Next, you'll learn
about stacking insulin.
