Dexcom G6 Sensor is a device used to monitor glucose levels continuously in patients with diabetes. It provides real-time glucose readings and sends them directly to a device such as a smartphone or Dexcom G6 receiver.
Dexcom G6 Sensor works by measuring glucose levels in your interstitial fluid—the fluid between your cells. A tiny sensor inserted under your skin does this. The sensor is connected to a transmitter which sends the data to the receiver, providing real-time glucose levels throughout the day and night.
The Dexcom G6 Sensor is a device, not a medication, so it does not come in "doses." The device provides ongoing readings of glucose levels.
Using the Dexcom G6 Sensor may cause minor side effects such as:
Skin irritation or redness around the sensor
Rash or itching at the site of the sensor
More serious side effects might include:
Severe skin irritation
Infection at the sensor site
If you experience severe side effects, consult your healthcare provider immediately. As this may not be a complete list of precautions, you should talk to your healthcare provider about any potential concerns before using Dexcom G6 Sensor.
Dexcom 6 sensors are usually inserted on the back of the upper arm or the abdomen, away from waistbands, tattoos, scars, or injection sites. Each sensor may be worn for up to 10 days.
The Dexcom G6 transmitter is designed to last for three months after its first use. Once activated, the transmitter battery cannot be recharged or replaced. To ensure continuous glucose monitoring, plan for a new transmitter every three months.
Follow the instructions that came with your Dexcom G6 to set up the system for the first time and each time you replace a sensor. If you have any questions, contact your healthcare professional or pharmacist, or refer to the information in the Dexcom G6 User Guide.

Both send alerts for out-of-range glucose readings
Dexcom G6 takes a new reading every 5 minutes. Freestyle Libre 2 takes a reading every 1 minute.
Dexcom G6 sensors are worn for 10 days. Freestyle Libre 2 sensors are worn for 15 days.
Cost may vary depending on insurance coverage. The out-of-pocket cost for Freestyle Libre 2 tends to be lower than Dexcom G6.
