Interfering substance risks
Hydroxyurea is a medication used in the treatment of diseases including cancer and blood disorders; it is known to interfere
with sensor readings.
If you are taking hydroxyurea, your sensor readings will be higher than your actual glucose, which could result in missed
hypoglycemia alerts or errors in diabetes management, such as giving yourself a higher dose of insulin due to falsely high
sensor glucose values. The level of inaccuracy depends on the amount of hydroxyurea in your body. Don't use your
Dexcom ONE+ System for diabetes treatment decisions if you are taking hydroxyurea. Talk to your physician about alternative
glucose monitoring approaches.
With Dexcom ONE+, you can take a standard or maximum paracetamol/acetaminophen dose of 1 gram (1,000mg) every 6
hours and still use the sensor 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 sensor readings and make them look
higher than they really are.
Sensor insertion risks
In rare cases, inserting the sensor can cause infection, bleeding, or pain, and wearing the adhesive patch can irritate your skin.
In most patients, the adhesive reactions are mild and resolve within a week. Only a few patients in the Dexcom ONE+ clinical
studies got slight redness and swelling. Although uncommon, some people get a significant reaction from the sensor adhesive
that may take weeks to resolve.
No sensor wires detached in clinical studies; however, there is a remote chance a sensor wire could break or detach and
remain under your skin. Sterile detached sensor wires usually don't pose a significant medical risk. If a sensor wire breaks off
or detaches, remains under your skin, and shows signs of infection or inflammation, contact your healthcare provider and

Benefits
Some benefits of using your Dexcom ONE+ are:
Sparing your fingertips
l
Knowing your trends
l
Making treatment decisions using your Dexcom ONE+
l
Managing your diabetes and getting alerted for low and high sensor readings
l
No fingersticks
You can use your sensor reading and trend arrow to make treatment decisions. Go to the
information. With Dexcom ONE+, there's no need to take fingersticks to calibrate the system or for treatment decisions (as
long as your symptoms match your Dexcom ONE+ readings). This can reduce the pain and burden of excessive fingersticks
(Price and Walker 2016) and reduce potential errors due to inaccurate calibration (Wadwa 2018).
Knowing your trends
Dexcom ONE+ not only sends you a sensor reading every 5 minutes but also provides overviews of your glucose trends and
patterns, and reaction to different activities. This lets you see the overall picture and how your daily habits impact your glucose
levels.
Helping your diabetes management
Alerts notify you when your glucose goes outside your target range. This lets you take action to prevent glucose from going too
low or too high (Pettus 2015) (go to the
Sharing with supporters
Some people perceive an increase in their quality of life and peace of mind when using real-time CGM (Polonsky and Fortmann
2020). Share may improve these for patients, their caregivers, and their support team because Followers can be notified by
sharing sensor readings and alerts remotely.
