Interfering Substances - Dexcom stelo Manual

Sensor insertion issues
In rare cases, inserting the sensor can cause infection, bleeding, or pain, and wearing
the adhesive patch can irritate your skin. For most people, the adhesive reactions are
mild and resolve within a week. Only a few participants in the 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. If a sensor wire
breaks off or detaches under your skin and you can't see it, don't try to remove it.
Contact your healthcare provider if you have symptoms of infection or inflammation
— redness, swelling, or pain — at the insertion site.

Interfering substances

Acetaminophen
With the Stelo Glucose Biosensor System you can take a standard or maximum
acetaminophen dose of 1 gram (1,000mg) every 6 hours and still use the Stelo
Glucose Biosensor System. Taking higher than the maximum dose of acetaminophen
(e.g. > 1 gram every 6 hours in adults) may affect the sensor readings and make them
look higher than they really are.
Hydroxyurea
Hydroxyurea makes your sensor readings look higher than they really are. How much
higher depends on the amount of hydroxyurea in your body. If you're taking
hydroxyurea, talk to your healthcare provider about alternative glucose monitoring
approaches.
Inaccurate sensor readings
Inaccurate sensor readings may lead to inappropriate lifestyle decisions. It is
recommended to use your readings and trends over time to help you make lifestyle
decisions. Don't make any medication adjustments based on your readings without
talking to your healthcare provider first.
