CHAPTER 17 • Important CGM Safety Information
hypoglycemia (low BG) or hyperglycemia (high
BG) events.
PRECAUTION
The Dexcom G6 CGM accuracy may be affected
when your sensor glucose is changing at a
significant rate (i.e., 2 to 3 mg/dL/min or more
than 3 mg/dL each minute), such as during
exercise or after a meal.
PRECAUTION
AVOID separating the transmitter and pump by
more than 20 feet (6 meters). The transmission
range from the transmitter to the pump is up to
20 feet (6 meters) without obstruction. Wireless
communication does not work well through
water so the range is reduced if you are in a
pool, bathtub, or on a water bed, etc. To ensure
communication, it is suggested that you face
your pump screen out and away from the body,
and wear the pump on the same side of the
body that you wear your CGM. Types of
obstruction differ and have not been tested. If
your transmitter and pump are farther than 20
feet (6 meters) apart or are separated by an
obstruction, they might not communicate or the
communication distance may be shorter and
result in you missing severe hypoglycemia (low
BG) or hyperglycemia (high BG) events.

PRECAUTION
DO NOT use alternative BG site testing (blood
from your palm or forearm, etc.) for calibration.
Alternative site BG values may be different than
those taken from a fingerstick BG value and may
not represent the timeliest BG value. Use a BG
value taken only from a fingerstick for
calibration. Alternative site BG values might
affect sensor accuracy and result in you missing
severe hypoglycemia (low BG) or hyperglycemia
(high BG) events.
PRECAUTION
ENSURE that your transmitter ID is programmed
into the pump before you use the System if you
receive a warranty replacement pump. The
pump cannot communicate with the transmitter
unless the transmitter ID is entered. If the pump
and transmitter are not communicating, you will
not receive sensor glucose readings and you
might miss severe hypoglycemia (low BG) or
hyperglycemia (high BG) events.
PRECAUTION
DO NOT discard your transmitter. It is reusable.
The same transmitter is used for each session
until you have reached the end of the transmitter
battery life.
PRECAUTION
The Dexcom G6 sensor is not compatible with
older versions of transmitters or receivers. Do
not mix transmitters, receivers, and sensors
from different generations.
PRECAUTION
Hydroxyurea is a medication used in the
treatment of diseases including cancer and
sickle cell anemia. It is known to interfere with
glucose readings from the Dexcom sensor. The
use of hydroxyurea will result in sensor glucose
readings that are higher than actual glucose
levels. The level of inaccuracy in sensor glucose
readings is based on the amount of hydroxyurea
in the body. Relying on sensor glucose values
while taking hydroxyurea could result in missed
hypoglycemia alerts or errors in diabetes
management, such as giving a higher dose of
insulin than necessary to correct falsely high
sensor glucose values. It can also result in
errors when reviewing, analyzing and
interpreting historical patterns for assessing
glucose control. DO NOT use the Dexcom CGM
readings to make diabetes treatment decisions
or assess glucose control when taking
hydroxyurea.
