When using the Dexcom G6 Continuous Glucose Monitoring (CGM) System, it's important to be aware of certain risks associated with the transmitter component to ensure your safety and the device's proper functioning.

Device Integrity and Electrical Safety

Before each use, carefully inspect the transmitter for any signs of damage, such as cracks or other defects. Using a damaged transmitter can lead to electrical hazards, including the risk of electric shock, and may cause the CGM system to malfunction. If you notice any damage, do not use the transmitter and contact Dexcom for a replacement.

Choking Hazard

The transmitter is a small device that can pose a choking risk, especially to young children. Always keep the transmitter out of reach of children, and do not allow them to handle it without adult supervision.

Interference with Medical Procedures

Do not wear the Dexcom G6 transmitter during medical procedures involving strong magnetic fields, such as Magnetic Resonance Imaging (MRI), Computed Tomography (CT) scans, or diathermy treatments. Exposure to these environments can damage the transmitter, leading to inaccurate glucose readings or device failure. Always remove the transmitter before undergoing such procedures.

Proper Use and Handling

The transmitter is designed for reuse across multiple sensor sessions until the system notifies you that the transmitter battery is nearing expiration. Do not discard the transmitter after a single use. Additionally, never share your transmitter with others, as it is intended for single-patient use. Sharing can lead to incorrect glucose readings and compromise the device's performance.

By adhering to these guidelines, you can help ensure the safe and effective use of your Dexcom G6 CGM System.

The Dexcom G6 Continuous Glucose Monitoring (CGM) system is designed to provide real-time glucose readings, aiding individuals in managing their diabetes effectively. The system comprises a sensor, a transmitter, and a display device (such as a receiver or compatible smart device). Understanding how the transmitter interacts with other components and external factors is crucial for optimal performance.

Device Compatibility and Pairing

The Dexcom G6 transmitter communicates via Bluetooth with a receiver or a compatible smart device. It's important to note that the transmitter can only be connected to one medical device at a time. However, it is possible to use the Dexcom mobile app and a compatible insulin pump, like the t:slim X2, simultaneously with the same transmitter ID. To ensure proper pairing, always enter the correct transmitter serial number into your display device. If you experience connectivity issues, verify that the transmitter ID is entered correctly and that the devices are within the recommended range.

Interference from Medications and Substances

Certain medications and substances can interfere with the accuracy of the Dexcom G6 sensor readings:

• Hydroxyurea: Used in the treatment of certain cancers and blood disorders, hydroxyurea can cause the sensor to display glucose readings higher than actual levels. This discrepancy may lead to missed hypoglycemia alerts or inappropriate insulin dosing. If you are taking hydroxyurea, consult your healthcare provider about alternative glucose monitoring methods.

• Acetaminophen: In doses exceeding 1,000 mg every six hours, acetaminophen may affect sensor readings, making them appear higher than they truly are. To minimize this risk, adhere to the recommended dosage limits when using the Dexcom G6 system.

• Other Substances: Research indicates that substances like Ethyl Alcohol, gentisic acid, hydroxyurea, l-cysteine, l-Dopa, and uric acid can also interfere with sensor readings. The extent of interference varies depending on the substance and its concentration.

Environmental Considerations

The Dexcom G6 components are labeled as "MR Unsafe" and should not be worn during magnetic resonance imaging (MRI), computed tomography (CT) scans, or diathermy treatments. Exposure to these environments can damage the device, leading to inaccurate readings or missed alerts. Always remove the sensor, transmitter, and receiver before undergoing such procedures.

Best Practices for Optimal Performance

• Device Placement: Ensure that the transmitter and display device are within 20 feet of each other without obstructions to maintain a reliable connection.

• Avoid External Substances: Keep the sensor site free from insect repellents, sunscreens, perfumes, or lotions, as these can affect sensor adhesion and performance.

• Regular Monitoring: Always pay attention to how you feel. If your symptoms don't match the sensor readings, use a blood glucose meter to confirm your glucose levels before making treatment decisions.

By understanding these interactions and following recommended guidelines, you can ensure the Dexcom G6 system functions accurately, providing reliable glucose monitoring to support your diabetes management.
