Dexcom one User Manual page 12

The Use By date is in YYYY-MM-DD
(Year-Month-Day) format on the sensor package
label, next to the hourglass symbol.
• Check package
Do not use sensor if its sterile package has been
damaged or opened, because it might cause an
infection.
• Clean and dry skin
Clean and dry your hands and your insertion site
before inserting your sensor.
Wash your hands with soap and water, not gel
cleaners, and then dry them before opening the
sensor package. If your hands are dirty when
you insert the sensor, you may get germs on the
insertion site and get an infection.
Clean your insertion site with alcohol wipes to
prevent infections. Do not insert the sensor until
your skin is dry. If your insertion site is not clean
and completely dry, you run the risk of infection
or the transmitter holder not sticking well.
Make sure you do not have insect repellent,
sunscreen, perfume, or lotion on your skin.
• Where to insert: things to check
Keep the safety guard on until you put the
Dexcom ONE applicator against your skin. If
you remove the safety guard first, you may hurt
yourself by accidentally pushing the button that
inserts the sensor before you mean to.
Change your insertion site with each sensor.
Using the same site too often might not allow
the skin to heal, causing scarring or skin
irritation.
Sensor placement is important. Choose a site:
• At least 8 cm from insulin pump infusion set
or injection site
• Away from waistband, scarring, tattoos,
irritation, and bones
• Unlikely to be bumped, pushed, or laid on
while sleeping
