Indications for Use and Safety Statement
Indications for Use
The Dexcom G5 Mobile Continuous Glucose Monitoring (CGM) System is a glucose
monitoring system indicated for detecting trends and tracking patterns in persons (age
2 years and older) with diabetes. The system is intended for single patient use and
requires a prescription.
The Dexcom G5 Mobile CGM System is indicated for use as an adjunctive device to
complement, not replace, information obtained from standard home glucose monitoring
devices.
The Dexcom G5 Mobile CGM System aids in the detection of episodes of hyperglycemia
and hypoglycemia, facilitating both acute and long-term therapy adjustments, which
may minimize these excursions. Interpretation of the Dexcom G5 Mobile CGM System
results should be based on the trends and patterns seen with several sequential
readings over time.
Contraindications
MRI/CT/ Diathermy
Remove the Dexcom G5 Mobile CGM System (sensor, transmitter, and receiver)
before Magnetic Resonance Imaging (MRI), Computed Tomography (CT) scan, or
high-frequency electrical heat (diathermy) treatment.
The system hasn’t been tested during MRI, CT scans, or with diathermy treatment.
Magnetic fields and heat could damage the components, stopping sensor glucose
readings or Alarm/Alert notifications. Without sensor glucose readings or Alarm/Alert
notifications, you might miss a severe low or high glucose event.
Medications
Taking medications with acetaminophen (such as Tylenol® or Excedrin Extra
Strength®) while wearing the sensor may falsely raise your sensor glucose readings.
The level of inaccuracy depends on the amount of acetaminophen active in your body
and is different for each person.
Dexcom G5 Mobile CGM System Quick Start Guide •5

General CGM System Warnings
Warnings
Review Training Materials
Thoroughly review the training materials included with your Dexcom G5 Mobile CGM
System before using.
Incorrect use could lead you to misunderstand system information or might affect its
performance and you might miss a severe low or high glucose event.
Treatment Decisions
The Dexcom G5 Mobile CGM System does not replace your blood glucose (BG) meter.
When making treatment decisions, such as the amount of insulin you need, only use
your BG value. Don’t use the Dexcom G5 Mobile CGM System sensor glucose readings
because readings can be different from your BG value. If sensor glucose readings are
used in determining treatments, it could result in you missing a severe low or high
glucose event.
Don’t Ignore Low/High Symptoms
If your sensor glucose readings don’t match your symptoms, measure your BG with a
fingerstick. Otherwise, you may miss a severe low or high glucose event.
Who Shouldn’t Use
The Dexcom G5 Mobile CGM System was not evaluated, nor approved for the following
persons:
• Pregnant women
• Persons on dialysis
• Persons who are critically ill
The system’s accuracy hasn’t been tested in people falling into these groups and sensor
glucose readings may be inaccurate, resulting in missing a severe low or high glucose
event.
Calibration Warning and Precautions
Warning
Calibrate on Schedule
Calibrate at least once every 12 hours. Calibrating less often than every 12 hours might
cause sensor glucose readings to be inaccurate, resulting in you missing a severe low
6 •Dexcom G5 Mobile CGM System Quick Start Guide

or high glucose event.
Precautions
Be Accurate, Be Quick
Enter the exact BG value displayed on your BG meter within five minutes of a
fingerstick.
Entering the wrong BG values, or waiting more than five minutes before entry, might
affect sensor performance, resulting in you missing a severe low or high glucose event.
Significant Glucose Rate Changes
Don’t calibrate when your BG is changing at a significant rate: more than 2 mg/dL per
minute.
Look for rate of change arrows on your display device screen and don’t calibrate when
you see:
• A single arrow, pointing up
- Rising 2-3 mg/dL each minute
• Two arrows pointing up
- Rising more than 3 mg/dL each minute
• Single arrow pointing down
- Falling 2-3 mg/dL each minute
• Two arrows pointing down
- Falling more than 3 mg/dL each minute
Calibrating during a significant rise/fall of your BG may affect accuracy of sensor
glucose readings, resulting in you missing a severe low or high glucose event.
Fingerstick Only
Only use fingerstick measurements from your BG meter for calibration.
Alternative site BG values from your arms, palm of your hand, etc., may be different
and less accurate than your fingerstick BG values. Using alternative site BG values for
calibration might affect sensor performance, resulting in you missing a severe low or
high glucose event.
Prior to Initial Calibration: Data/Alarm/Alert
After starting a new sensor session, until completing your initial calibrations, you won’t
receive any sensor information such as readings, Alarm or Alerts. Without these, you
may miss a severe low or high glucose event.
Continue to take fingerstick measurements during a new sensor warmup period.

System/Hardware/Software Warnings and Precautions
Sensor/Sensor Pod Warnings and Precautions
Warnings
Sensor Breaking Off
On rare occasions, the sensor wire may break or detach from the sensor pod.
Within 24 hours of experiencing a broken sensor wire, please call our 24/7 Technical
Support department, toll free at 1.877.339.2664 or toll at 1.858.200.0200.
If a sensor wire breaks under the skin with no portion of it visible, don’t remove it.
Contact your healthcare professional if you have redness, swelling, or pain at the
insertion site.
Placement
Do not insert the sensor component of the G5 Mobile System in a site other than the
belly/abdomen (ages 2 years and older) or the upper buttocks (ages 2 to 17 years).
The placement and insertion of the sensor component of the G5 Mobile System is not
approved for other sites.
If placed in other areas, the G5 Mobile System may not function properly
Storage
During a sensor’s shelf life, store it between 36° F-77° F. While you don’t need to keep
your sensor in a refrigerator, you can as long as the refrigerator is between 36° F-77° F.
Never store sensors and/or sensor packages in a freezer.
Storing the sensor incorrectly might cause the sensor glucose readings to be incorrect,
resulting in you missing a severe low or high glucose event.
Precautions
Expiration Date
Don’t use expired sensors. Before inserting, always check the package label for the
expiration date using the YYYY-MM-DD format.
If past the expiration date, don’t use because the sensor glucose readings might not be
accurate, resulting in you missing a severe low or high glucose event.
Sensor Package
Don’t use sensor if its sterile package has been damaged or opened. Using a
non-sterile sensor might cause infection.
8 •Dexcom G5 Mobile CGM System Quick Start Guide

Clean and Dry Before Using
Before opening the sensor package, wash your hands with soap and water, then dry. If
your hands are dirty while inserting the sensor, you may contaminate the insertion site
and get an infection.
Before sensor insertion, clean the skin with alcohol wipes to prevent infections. Don’t
insert the sensor until the cleaned insertion site is dry, and free from any lotions or
perfumes.
If your insertion site is not clean and completely dry, you run the risk of infection or the
sensor pod not sticking and falling off.
Sensor Placement
Change the site where you place the sensor with each new insertion. Using the same
site too often might not allow the skin to heal, causing scarring or skin irritation.
Sensor placement is important. Make sure the area you place your sensor won’t:
• Be bumped, pushed, or squeezed
• Have scars, tattoos, or irritation
Insertion in these areas might affect sensor performance, resulting in you missing a
severe low or high glucose event.
Avoid injecting insulin or placing an insulin pump infusion set within three inches of the
sensor. The insulin might affect sensor performance, resulting in you missing a severe
low or high glucose event.
Transmitter Warnings and Precautions
Warnings
Inspect Transmitter
If your transmitter is damaged or cracked in any way, don’t use it. Damaged
components could create an electrical safety hazard or malfunction, which might cause
electrical shocks.
Choking
The transmitter is small and may pose a choking hazard. Don’t put it in your mouth or
allow children to play with it.
Precautions
Reusable: Don’t Throw Away
Dexcom G5 Mobile CGM System Quick Start Guide •9

When ending a session, don’t throw away the transmitter.
The transmitter is reusable and can be used in multiple sensor sessions. Keep using it
until the system notifies you the transmitter battery is about to expire.
Don’t Share Your Transmitter
Never share your transmitter with another person. The Dexcom G5 Mobile CGM System
is a prescription-only medical device and is meant, or indicated, for your use only.
Your transmitter is tied to your readings. If used by someone else, your reports, Alarm
and Alerts, etc., would be wrong, resulting in you missing a severe low or high glucose
event.
System Precautions
Precautions
Use Correct Transmitter, Receiver, and Sensor
Different generations’ transmitters and receivers aren’t interchangeable with each
other.
The Dexcom G5 Mobile CGM System’s transmitter and receiver are not compatible with
the Dexcom G4® PLATINUM CGM System’s transmitter and receiver. The Dexcom G5
Mobile CGM System won’t work if you mix receiver and transmitter components from
different generations, resulting in you missing a severe low or high glucose event.
You can use a Dexcom G4 PLATINUM Sensor with the Dexcom G5 Mobile CGM System.
Before using the sensor, make sure the sensor label says G5 Mobile or G4 PLATINUM
Sensor.
System Accuracy
System accuracy may be affected when your glucose is changing at a significant rate
such as during exercise or after a meal.
Significant glucose rise/fall rates:
• Rising 2-3 mg/dL each minute
• Rising more than 3 mg/dL each minute
• Falling 2-3 mg/dL each minute
• Falling more than 3 mg/dL each minute
Receiver and Smart Device Precautions
Precautions
Communication Range
10 •Dexcom G5 Mobile CGM System Quick Start Guide

Do not separate the transmitter from the receiver or smart device by more than 20 feet.
The transmission range from the transmitter to receiver or smart device is up to 20 feet
without obstruction.
Types of obstruction differ and not all have been tested. Obstructions can include water,
walls, metal, etc. If your transmitter and display device(s) are more than 20 feet from
each other or are separated by an obstruction, they might not communicate, resulting
in you missing a severe low or high glucose event.
Water is often the biggest culprit in reducing the communication distance between the
transmitter and display devices. Take special care when swimming, taking a bath, or
getting into a hot tub.
Setting Alarm/Alert Notifications
When using both a receiver and a smart device, you must set your settings separately in
each. If you set up one device and then use another device with different settings, you
might not get an Alarm or Alerts, causing you to miss a severe low or high glucose event.
Using an accessory device (like a smart watch) might override your smart device
sounds. Alarms or Alerts might vibrate or be heard on the accessory instead of your
smart device. After connecting any accessories, make sure that the smart device
settings allow you to continue receiving Alarms or Alerts on the smart device.
Is It On?
If the receiver or smart device is turned off (Shut Down), it will not display sensor
information, Alarm or Alerts. Make sure they are turned on; otherwise you won’t get
sensor glucose readings or Alarm or Alerts, causing you to miss a severe low or high
glucose event.
Smart Device Warnings
Warnings
Smart Device Settings
The Dexcom G5 Mobile App cannot override your smart device’s internal settings. Also,
accessory devices (like a smart watch or other wearable smart devices) might override
your smart device’s Alerts, Alarm, and notification settings.
To receive Alarm or Alerts you must:
1. Make sure Dexcom G5 Mobile App Notifications are turned on in your smart
device’s settings
2. Verify app hasn’t been shut down
Dexcom G5 Mobile CGM System Quick Start Guide •11

3. Turn Bluetooth on
4. Turn off Do Not Disturb (if available on your smart device)
5. Restart app after device is restarted
6. Set Volume at a level you can hear
7. Do not close app, always run app in the background
8. Make sure accessory devices do not override your smart device settings.
If your settings are incorrect, you might miss a severe low or high glucose event.
Dexcom G5 Mobile CGM System Alarm/Alert vibrations aren’t any different from other
vibrating apps on your smart device. Medical device apps, like the Dexcom G5 Mobile
App, don’t have any special priorities over your smart device’s features. Dexcom G5
Mobile App notifications or alerts may sound or feel the same as notifications from
another app. The only way to know is to look at the screen.
Missed an Alarm or Alert?
An Alarm or Alert can’t be heard through your smart device’s speakers if headphones
are plugged in.
Make sure you unplug your headphones when you are done using them, otherwise you
might not hear an Alarm or Alert, causing you to miss a severe low or high glucose event.
Receiver Warning and Precaution
Warning
Don’t Use Damaged Goods
If your receiver is damaged or cracked, don’t use it. This could create an electrical
safety hazard or malfunction, causing possible electrical shocks.
Precaution
Keep Receiver Dry
Keep the USB port cover on the receiver closed whenever the USB cable is not attached
and do not submerge in water.
If water gets into the USB port, the receiver could become damaged and stop
displaying readings or providing alerts; you might miss a severe low or high glucose event.
Caution
U.S. law restricts the sale of the Dexcom G5 Mobile CGM System to sale by or on order
of a physician.

Section 3
Risks and Benefits
3.1 Risks
There are some risks with using real-time CGM.
Not Receiving Alarm/Alerts
If you aren’t getting your CGM Alarm/Alerts, you run the risk of not knowing you are
having a severe glucose low or high.
Some hardware issues preventing Alarm/Alerts:
• Alert function is turned off
• Transmitter and display device is out of range
• Receiver or smart device isn’t showing sensor glucose readings
• Receiver or smart device battery is dead
• Unable to hear Alarm/Alerts or feel vibration
• App not running in the background
• Smart device is in Do Not Disturb
Sensor Glucose Reading Different from Meter’s
The sensor glucose reading can be different than your meter’s BG value.
If you’re not receiving an Alarm/Alert, and not taking fingerstick BG measurements, you
may be unaware of low or high glucose levels.
Sensor Insertion Risks
Inserting the sensor and wearing the adhesive patch might cause infection, bleeding,
pain or skin irritations (e.g., redness, swelling, bruising, itching, scarring or skin
discoloration).
There is a remote chance sensor fragments could remain under your skin if the sensor
breaks during normal wear. Sterile broken sensor wires don’t pose a significant
medical risk.
If a sensor wire breaks off or detaches and remains under your skin, contact your
healthcare professional and call Dexcom’s Technical Support toll free, 24/7, at
1.877.339.2664 or toll at 1.858.200.0200 within 24 hours.

3.2 Benefits
Daily habits impact your glucose levels. With the Dexcom G5 Mobile CGM System, you
can track how your exercise, carbs, stress levels, medication, or illness, influence your
glucose levels.
Knowing Your Trends
Providing sensor glucose readings every five minutes, for up to seven days, the
Dexcom G5 Mobile CGM System helps you detect trends and patterns. Trend
information reveals where your glucose is now, where your glucose is heading, and
how fast it’s changing.
Helps in Your Diabetes Management
The Alarm/Alerts features keep you aware of your glucose levels. Alerts notify you
when your glucose goes outside your target range or is rapidly falling or rising,
informing you to take action before you get too low or too high. The Urgent Low Alarm
lets you know when you are dangerously or urgently low, going below 55 mg/dL. By
taking corrective measures, you lessen the time spent in your low/high range, while
increasing time in your targeted range (Garg, 2006; Battelino, 2011).
Real-time CGM can help improve your A1C as well as improve the quality of your
glucose control. If you are at or below 7%, using a CGM such as Dexcom’s G5 Mobile
CGM System, helps reduce hypoglycemia (Tamborlane, 2008).
Lowering your A1C, increasing your time in your target range while decreasing time
in low/high BG range is believed to reduce your risk of diabetes related complications
(Ohkubo, 1995).
When you use your CGM device regularly, you get peace of mind. (Juvenile Diabetes
Research Foundation Continuous Glucose Monitoring Study Group. 2010)
