Are you Looking to Buy Dexcom G6 Sensor (Glucose Sensor) from PrescriptionPoint.

Dexcom G6 Sensor (glucose meter)

Indications

Dexcom G6 Sensor (glucose meter) is indicated for managing diabetes in individuals aged 2 years and older. The system replaces fingerstick blood glucose testing for diabetes treatment decisions and helps detect episodes of hyperglycemia and hypoglycemia. It also supports both immediate and long-term therapy adjustments. Additionally, it can communicate with digitally connected devices, including automated insulin dosing (AID) systems.

Ingredients

Dexcom G6 Sensors are products, not medications, so there are no active or inactive ingredients. Instead, they are medical devices made up of three key components: the sensor, the transmitter, and the display device. The sensor consists of a tiny, flexible wire that is inserted under the skin using a preloaded applicator. This wire continuously measures glucose levels in interstitial fluid for up to ten days. Once inserted, the reusable transmitter is snapped into place, allowing it to wirelessly send glucose readings to a display device, such as a smartphone or receiver. The display device collects and presents real-time glucose data, showing trends, alerts, and reports for effective diabetes management. The sensor is designed with materials that ensure sterility and safety, undergoing radiation sterilization before use. Additionally, the transmitter is water-resistant, making it durable for daily activities. While no source provides specific details about the materials used in the sensor, it emphasizes proper handling and storage to maintain accuracy and performance.

Directions

Follow your doctor’s instructions exactly. Read the patient information leaflet and medication guide before using the Dexcom G6 sensor or when replacing it. Ask your healthcare provider if you have any questions. Choose the right site before applying the sensor. The abdomen is suitable for all patients, while those aged 2 to 17 can also use the upper buttocks. Pick a site with enough padding.

Do not use alternative sites without consulting your healthcare provider. Check the use-by date before applying the sensor. Do not use it if the sterile package is opened or damaged, as this may increase infection risk. During sensor setup, enter the calibration code. If the code is used, no further calibration is needed for the 10-day sensor lifespan. If the code is missing, perform manual calibration using two fingerstick blood glucose tests at startup and every 24 hours. The Dexcom G6 sensor comes with a disposable applicator. To use it, wash your hands with soap and water, not gel cleaners.

Clean the application site with alcohol wipes and let it dry. Remove both labels without touching the adhesives, then place the applicator against your skin. Fold and break off the safety guard. Press the button until you hear a click. Discard the applicator. After inserting the sensor, place the transmitter into the slot to send readings to the app or receiver. Rotate the insertion site with each new sensor to avoid irritation or scarring. When choosing a site, keep it at least 3 inches away from insulin pump infusion sets or injection sites. Avoid scars, tattoos, irritated skin, or bony areas. Pick a spot that won’t be bumped, pushed, or compressed during sleep. Please read the instructions before using the Dexcom G6 Sensor.

Do not use Dexcom G6 if you are pregnant, on dialysis, or critically ill, as it is unknown how these conditions may affect the sensor’s performance. Avoid using the sensor during MRI, CT scans, or diathermy treatment, as the strong magnetic fields and heat could damage it, leading to inaccurate glucose readings. Do not use it if the sterile packaging is damaged or opened, as this may cause infection. The sensor should not be worn past its expiration date, as it may provide incorrect readings.

Side Effects

Using the Dexcom G6 Sensor may pose serious risks if incorrect readings influence treatment decisions or if hardware or setup issues prevent alarms and alerts from functioning properly. Contact your healthcare provider if you experience any of the following signs:

• Signs of Hypoglycemia (Low Blood Sugar) include hunger, shakiness, anxiety, sweating, pale skin, fast or irregular heartbeat, sleepiness, dizziness, crankiness, confusion, blurred vision, passing out, loss of consciousness, or seizures. Signs of Hyperglycemia (High Blood Sugar) include thirst, headaches, trouble concentrating, blurred vision, frequent urination, fatigue, weight loss, and blood sugar levels above 180 mg/dL.
• Rare Side Effects at the insertion site include skin irritation, redness, infection, bleeding, and pain. Seek assistance from your healthcare provider if you experience any of these.

This list of signs is not complete. In case you experience other signs, contact your doctor immediately.

Precautions

Before using the Dexcom G6, tell your doctor about your health, allergies, medications, pregnancy, or breastfeeding status. These may affect how you use the device.

Accuracy: The G6 reads glucose from interstitial fluid, not blood. Readings may differ from your blood glucose meter. If the difference is 20%-29%, you can still use the G6, but trust your meter if your symptoms don’t match the G6. If it’s over 30%, the G6 may be inaccurate. Consider calibrating or replacing the sensor.

Allergies: Some may be allergic to the adhesive. If you notice itching, burning, or rash, contact your doctor.

Calibration: The G6 doesn’t need regular calibration. Enter the correct sensor code when starting a new sensor. If the code is lost, calibrate using a blood glucose meter within 5 minutes.

Device Compatibility: Not all smart devices work with the G6. Check compatibility before pairing.

Insulin Stacking: Taking insulin doses too close together can cause low glucose. Talk to your doctor if the G6 readings aren’t changing as expected.

Notifications: Check that Bluetooth is on, and notifications are enabled if you’re not receiving alerts. Ensure your device is charged.

Security Screening: Avoid body scanners and baggage x-rays. Ask for a hand-wand or pat-down. Metal detectors are safe.

Sensor Site Rotation: Rotate sensor sites to prevent skin irritation or scarring.

Sensor Wires: Rarely, wires may detach under the skin. Contact your doctor and support if this happens.

Skin Care Products: Avoid contact with lotions, sunscreens, insect repellents, or perfumes. They can damage the G6 system.

Sounds: If you can’t hear alarms or alerts, check your device volume and settings. Make sure “Do Not Disturb” and Bluetooth are off.

Time Zones: Set your device to adjust the time automatically to avoid issues.

Transmitter Range: The transmitter works within 6 meters (20 feet). The range reduces underwater.

Treatment Decisions: Use your blood glucose meter to make decisions, especially on the first day of use or if symptoms don’t match the G6.

Water Damage: The G6 transmitter is water-resistant, but the receiver is not. Keep the receiver dry.

Drug Interactions

• Hydroxyurea used for cancer and blood disorders, can cause falsely high glucose readings. Avoid using the Dexcom G6 for diabetes management if taking hydroxyurea.
• Acetaminophen (Paracetamol) doses higher than 1 gram every 6 hours may falsely elevate sensor readings. Standard doses up to 1 gram every 6 hours are generally safe.

If you are taking these medications, consult your healthcare provider for alternative glucose monitoring methods.

Storage

Store the Dexcom G6 sensor between 36°F and 86°F (room temperature or refrigerated). Do not store it in the freezer. Keep sensors in their sterile package until ready for use.
