Using Dexcom ONE for treatment
decisions
You can use your Dexcom ONE for treatment
decisions in all but a few situations.
Situation: How you feel is inconsistent with your
Dexcom ONE reading
Treatment Decision Tool: Take a fingerstick for a
BG measurement and use the number to make a
treatment decision
Situation: Your CGM display is missing Dexcom ONE
reading (number) or arrow(s), or both
Treatment Decision Tool: Take a fingerstick for a
BG measurement and use the number to make a
treatment decision
Some users found accuracy between different
sensors varied significantly. When you insert each
sensor, pay attention to its accuracy before deciding
to use it for treatment decisions.
For more information on how to make treatment
decisions using your Dexcom ONE, go to Chapter 5.
Paracetamol/acetaminophen
interfering substance risks
With the Dexcom ONE, you can take a standard
or maximum paracetamol/acetaminophen dose
of 1 gram (1,000mg) every 6 hours and still use
the Dexcom ONE readings to make treatment
decisions. Taking higher than the maximum dose of
paracetamol/acetaminophen (e.g. > 1 gram every 6
hours in adults) may affect the Dexcom ONE readings
and make them look higher than they really are.
Hydroxyurea interfering
substance risks
Hydroxyurea, a medication used to treat some
cancers or blood disorders, may falsely elevate
your Dexcom ONE readings and result in missed
hypoglycemia alerts or errors in diabetes
management decisions. The level of inaccuracy
depends on the amount of hydroxyurea in your
body. Use your BG meter.
