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

Sensor Fractures: On rare occasions, the sensor may break or detach from its pod. If this happens and no part of the sensor is visible above the skin, do not attempt to remove it yourself. Seek medical assistance, especially if you notice signs of infection or inflammation, such as redness, swelling, or pain at the insertion site.

Device Damage: Do not use the Dexcom G6 receiver or transmitter if they are damaged or cracked. Using damaged components can pose electrical hazards, potentially leading to injury, and may cause the system to malfunction.

Choking Hazard: The sensor and transmitter contain small parts that could be a choking risk. Keep these components out of reach of young children and ensure they are used only under adult supervision.

Calibration and Accuracy: The Dexcom G6 is designed to function without routine fingerstick calibrations. However, if your glucose alerts and readings do not match your symptoms or expectations, use a fingerstick blood glucose value from your blood glucose meter to make diabetes treatment decisions.

Device Compatibility: Ensure that you are using compatible components. Different generations of Dexcom CGM transmitters and receivers are not interchangeable. Mixing components from different generations can result in the system not functioning properly.

Communication Range: Maintain a distance of no more than 6 meters between the transmitter and receiver. Obstructions or greater distances can disrupt communication, leading to missed glucose readings or alerts.

Alarm and Alert Settings: When using both a receiver and a smart device with your Dexcom G6 system, set your alarm and alert settings separately on each device. Failing to do so may result in missed alarms or alerts.

Device Maintenance: Keep the receiver dry and ensure the USB port cover is closed when not in use. Exposure to water can damage the receiver, preventing it from displaying readings or providing alerts.

Sensor Storage: Store sensors at temperatures between 2°C and 25°C. Do not use sensors beyond their expiration date, as this can affect accuracy.

Sensor Placement: Rotate sensor insertion sites to prevent skin irritation or scarring. Avoid areas likely to be bumped or compressed, and do not insert the sensor into areas with scarring, tattoos, or irritation, as these can affect accuracy.

Medical Procedures: Remove the sensor, transmitter, and receiver before undergoing Magnetic Resonance Imaging (MRI), Computed Tomography (CT) scans, or diathermy treatments. These procedures can damage the device components, leading to inaccurate readings or device failure.

By adhering to these guidelines, you can minimize risks and ensure the Dexcom G6 CGM System functions effectively in managing your diabetes.

The Dexcom G6 Continuous Glucose Monitoring (CGM) system is a valuable tool for managing diabetes, providing real-time glucose readings. However, certain substances can interfere with its accuracy, leading to incorrect glucose measurements. It's important to be aware of these potential interactions to ensure effective diabetes management.

Hydroxyurea: This medication, used to treat conditions like cancer and sickle cell anemia, can cause the Dexcom G6 sensor to display glucose readings higher than actual levels. This discrepancy may result in missed low blood sugar alerts or incorrect insulin dosing. If you're taking hydroxyurea, it's recommended not to rely on the Dexcom G6 for treatment decisions and to consult your healthcare provider for alternative glucose monitoring methods.

Acetaminophen (Tylenol): While the Dexcom G6 has improved resistance to acetaminophen interference compared to earlier models, consuming more than 1 gram (1,000 mg) every six hours can still lead to falsely elevated glucose readings. To maintain accurate sensor readings, avoid exceeding this dosage.

Other Substances: Research indicates that substances such as Ethyl Alcohol, gentisic acid, l-cysteine, l-dopa, mannose, N-Acetyl-Cysteine, and uric acid may also affect the Dexcom G6 sensor's accuracy. These substances can cause the sensor to display glucose readings that are either higher or lower than actual levels. Additionally, exposure to certain substances like dithiothreitol, gentisic acid, l-cysteine, and mesalazine has been associated with sensor malfunction, necessitating sensor replacement.

To ensure accurate glucose monitoring, it's crucial to be aware of these potential interactions. If you're taking any of these substances, discuss with your healthcare provider how they might affect your Dexcom G6 readings and consider alternative monitoring strategies if necessary.
