Dexcom G7 User Manual page 18

Clean and dry skin: If your insertion site and hands aren't clean and dry, you run the
risk of infection and the sensor not sticking well. Clean your insertion site with alcohol
wipes to prevent infections. Before insertion and during your sensor session, don't
apply insect repellent, sunscreen, perfume, or lotion on your insertion site or sensor.
This may cause the sensor to not stick well or could damage your Dexcom G7 CGM
System.
Hydroxyurea: If you are taking hydroxyurea, your sensor readings may be falsely
elevated 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 meter if you have taken hydroxyurea.
Be accurate, be quick: If you calibrate your Dexcom G7 CGM System using your BG
meter, enter the BG value on your meter within five minutes of measuring your BG.
Use fingertips: Use a BG sample from your fingertips when calibrating as blood
glucose from other places may be less accurate and not as timely. Calibration is not
required but you can do optional BG calibration to align with your meter.
Don't start past the Use By Date: Don't start a sensor past its Use By Date
(YYYY-MM-DD) because it may give incorrect results. You can start a new sensor on or
before its Use By Date. This gives you full wear.
Check package: Don't use your Dexcom G7 CGM System if the applicator and/or
sterile cap has been damaged or opened, because it might cause an infection. Don't
remove cap until ready for insertion.
Where to insert — things to check: The Dexcom G7 CGM System insertion safety
guard is enabled until you press the Dexcom G7 CGM System applicator down against
your skin. Only do this when ready to insert.
Change your insertion site with each sensor to allow the skin to heal.
