The Dexcom G6 Sensor is a component of the Dexcom G6 Continuous Glucose Monitoring (CGM) System. It is a small device that is inserted just beneath the skin to continuously measure glucose levels. It can be used with a compatible smart device or a touch screen receiver as a display device.

The Dexcom G6 Sensor works by continuously measuring glucose levels in the interstitial fluid, which is the fluid between the cells in your tissues. The sensor wirelessly sends real-time glucose readings to a compatible smart device or Dexcom receiver.

Sensors for the Dexcom G6 system should be worn continuously for up to 10 days. You will receive alerts on your display device to replace the sensor starting 24 hours before your sensor session ends. If you need to remove the sensor before 10 days, you can end the session early using the feature in your G6 app or G6 receiver settings.

Use and Dosage

The sensor is factory calibrated by entering the sensor code into the display device, eliminating the need for fingerstick calibration. The sensor wirelessly communicates with a transmitter, which sends real-time glucose readings to a compatible smart device or Dexcom receiver.

Before opening the sensor package, wash your hands with soap and water (avoid hand sanitizer or gel cleaners). Clean the area where you plan to insert the sensor with alcohol wipes. Wait until the skin is dry before inserting the sensor to help it stay attached. Keep the safety guard on the Dexcom G6 applicator until you are ready to use it.

Remove the sensor applicator from the packaging and peel off the adhesive backing. Place the sensor on a clean, dry area of your skin (typically the abdomen for adults) and press down firmly to secure it in place. Remove the transmitter from its packaging and align it with the sensor. Press down firmly to attach the transmitter to the sensor. Follow the instructions on your Dexcom receiver or compatible smart device to start the sensor. This usually involves entering the sensor code and confirming the start of the sensor session.

The Dexcom G6 Sensor requires a two-hour warm-up period before it starts providing glucose readings. During this time, you may see a "no data" message on your receiver or smart device. Unlike previous Dexcom systems, the G6 does not require routine fingerstick calibrations. The sensor is factory calibrated, so you do not need to manually enter blood glucose readings for calibration.

Once the warm-up period is complete, the Dexcom G6 Sensor will start providing real-time glucose readings. You can view these readings on your receiver or compatible smart device.

Side Effects

Common Side Effects of Dexcom G6 Sensor (Glucose Sensor):

  • Skin irritation: Some users may experience skin irritation, redness, swelling, or blistering at the sensor site.
  • Skin hypersensitivity reaction: For certain users, the skin reaction may be more severe and classified as a hypersensitivity reaction rather than a simple irritation.

Forms and Strength

Dexcom G6 Sensor (Glucose Sensor) is available in the following forms and strength:

Dexcom G6 Sensor: Blood-glucose sensor

  • No dose


  • Some users may experience skin irritation or allergic reactions at the insertion site. Follow the instructions for sensor placement and adhesive removal to minimize the risk of skin irritation.
  • While the Dexcom G6 Sensor is designed to provide accurate glucose readings, there can be variations and discrepancies compared to blood glucose readings. Use a blood glucose meter for diabetes treatment decisions if glucose alerts and readings from the G6 do not match symptoms or expectations.
  • The Dexcom G6 Sensor may be affected by electromagnetic interference from other devices, such as smartphones, tablets, or medical equipment. Keep the sensor and transmitter away from sources of interference to ensure accurate readings.
  • Proper insertion of the sensor is crucial for accurate readings and comfort. Users should carefully follow the instructions for sensor insertion to ensure proper placement and avoid complications.
  • The Dexcom G6 Sensor requires a two-hour warm-up period before it starts providing glucose readings. During this time, glucose data may not be available, and users should rely on alternative glucose monitoring methods.
  • The Dexcom G6 Sensor should be used under the guidance of a healthcare professional. Consult with your healthcare provider for personalized instructions, training, and support.

Frequently Asked Questions (FAQ)

How often should I replace the Dexcom G6 sensor?

The Dexcom G6 sensor should be replaced every 10 days. After 10 days, you should remove the old sensor and insert a new one.

Can the Dexcom G6 sensor be worn during water activities or while swimming?

Yes, the Dexcom G6 sensor is water-resistant and can be worn while swimming or participating in water activities. However, avoid prolonged submersion in water, such as hot tubs or saunas, as it may affect the sensor's performance.

Can I calibrate the Dexcom G6 sensor?

No, the Dexcom G6 sensor is factory-calibrated, which means there is no need for manual calibration by the user. The sensor is designed to provide accurate glucose readings without the need for fingerstick calibrations.
