Eversense CGM Safety Information
Indications for Use
The Eversense CGM System is indicated for continually measuring interstitial fluid glucose levels in adults (18 years and older) with diabetes for the operating life of the sensor.
The system is intended to:
- Aid in the management of diabetes.
- Provide real-time glucose readings.
- Provide glucose trend information.
- Provide alerts for the detection and prediction of episodes of low blood glucose (hypoglycemia) and high blood glucose (hyperglycemia).
Historical data from the system can be interpreted to aid in providing therapy adjustments. These adjustments should be based on patterns and trends seen over time.
The system is indicated for use as an adjunctive device to complement, not replace, information obtained from standard home blood glucose monitoring devices.
The sensor and smart transmitter are incompatible with magnetic resonance imaging (MRI) procedures. Patients should not undergo an MRI procedure while the sensor is inserted or when wearing the smart transmitter. Should an MRI be required the sensor must be removed before the procedure.
- The system is contraindicated in people for whom dexamethasone or dexamethasone acetate may be contraindicated.
- Therapeutics products such as mannitol intravenous and irrigation solutions may increase blood mannitol concentrations and cause falsely elevated readings of sensor glucose results.
DO NOT use the Eversense apps on jailbroken iPhones or iPods. Jailbroken devices do not provide an acceptable level of security and accuracy for the user and are not approved for use by Senseonics.
Broken Screen or Button
If the screen of your mobile device is broken, or the buttons do not work, then you may not be able to use your Eversense System and you may miss low or high glucose events.
Risks and Side Effects
The glucose alerts and notifications will not audibly notify the user when the sound on your mobile device is turned off. If the system cannot display a glucose value, it also cannot provide glucose alerts. If you are unable to feel the vibration of the smart transmitter you may not notice the alerts. The system’s calculated glucose can be slightly different from your blood glucose meter. This may cause an alert to activate at a different time than it would have if the system’s values always matched the blood glucose meter values.
If you do not take frequent blood glucose measurements and miss an alert, you may not be aware of high or low glucose levels. You may need medical attention in the event that you have high or low glucose and are unaware of it.
If you do not test your glucose with a blood glucose meter when you have symptoms of a low or high blood glucose level OR when your symptoms are not consistent with the sensor glucose readings, you may miss a high or low glucose event. Treatment decisions made without confirming with a blood glucose meter check may result in a high or low glucose event, since blood glucose values can be slightly different than your sensor glucose values measured in interstitial fluid.
The sensor is inserted by making a small incision and placing it under the skin. This process may cause infection, pain or skin irritation. Additionally, the adhesive may cause a reaction or skin irritation.
- If at any time you have symptoms of a low or high blood glucose level OR if your symptoms are not consistent with the sensor glucose readings, you should test your glucose with a blood glucose meter.
- Always test your glucose with your blood glucose meter before making a treatment decision.
- If your smart transmitter is damaged or cracked, DO NOT use, as this could create an electrical safety hazard or malfunction, and could result in electrical shock.
- Close contact with direct EMI may interfere with the smart transmitter’s ability to send data to your mobile device. Move away from the source of EMI and check that your mobile device is connected to your smart transmitter.
- High doses of aspirin (over 2000 mg), such as for chronic treatment of inflammatory conditions (e.g., rheumatoid arthritis), may falsely lower Sensor glucose readings.
- Until it has healed, always cover the insertion site with a sterile bandage before placing the smart transmitter adhesive over the sensor. Failure to do so could result in infection at the insertion site.
- Please review the Eversense CGM System User Guide with your health care provider. For additional Eversense product questions and troubleshooting issues, contact Customer Support toll free in the US at 844-SENSE4U (844-736-7348). Outside the US, call your local distributor or visit www.eversensediabetes.com to locate your local distributor.
- Always calibrate the system using only a fingerstick blood sample. DO NOT use an alternative site (such as forearm or palm) blood glucose reading to calibrate the system.
- DO NOT insert your infusion set within 10.16 cm (4 in) of the sensor site. If the insulin delivery site is within 10.16 cm (4 in) of the sensor site, it may interfere with sensor glucose readings and can cause inaccurate glucose readings.
Always follow your physician’s instructions for care after the sensor insertion or removal. Contact your physician if any of the following events occur:
- You have pain, redness, or swelling at the incision site(s) later than 5 days after the sensor insertion or removal.
- DO NOT exchange smart transmitters with another person. Each smart transmitter can be linked to only one sensor at a time.
- The following medical therapies or procedures may cause permanent damage to the sensor particularly if used in close proximity to the device:
- Lithotripsy – The use of lithotripsy is not recommended for people who have an inserted sensor because the effects are unknown.
- Diathermy – DO NOT use diathermy on people who have an inserted sensor. Energy from the diathermy can transfer through the sensor and cause tissue damage in the insertion area.
- Electrocautery – The use of electrocautery near the inserted sensor may damage the device. DO NOT use electrocautery near the sensor.
- DO NOT wear the smart transmitter during medical x-rays or computed tomography (CT) scans. To avoid interference with results, remove the smart transmitter before undergoing medical x-ray or CT scans. Make sure your physician knows about your smart transmitter.
- The sensor and smart transmitter should be linked the day of insertion. Failure to link the sensor and smart transmitter could result in a delay in receiving glucose readings.
- Steroid use – It has not been determined whether the risks usually associated with injectable dexamethasone acetate apply to the use of this dexamethasone acetate elution ring, a highly localized, controlled-release device. The dexamethasone acetate ring could cause other adverse events not listed or previously seen.
- If the sensor or smart transmitter feels warm, remove the smart transmitter immediately and contact your physician for further advice. A warm sensor could mean there is an infection or a sensor malfunction.
- Remove the smart transmitter from your arm before charging the smart transmitter battery. Failure to remove the smart transmitter while it is charging could result in electrical shock.
- DO NOT attempt to use the Eversense App while operating a motor vehicle.
- You should not receive massage therapy near the inserted sensor site. Massage therapy near the sensor site could cause discomfort or skin irritation.
- Use only the AC power adapter and USB cable provided with the smart transmitter when charging the smart transmitter battery. Use of another power supply could damage the smart transmitter, not allowing glucose readings to be received properly, and could result in voiding your warranty.
- If you have any concerns about allergic reaction to silicones, contact your physician prior to use.
- Discard the patch after 24 hours of use.
- The Eversense CGM System has not been tested in the following populations: women who are pregnant or nursing, people under the age of 18, critically ill or hospitalized patients, people receiving immunosuppressant therapy, chemotherapy or anti-coagulant therapy, those with another active implantable device, e.g., an implantable defibrillator (passive implants are allowed, e.g., cardiac stents), those with known allergies to or using systemic glucocorticoids (excluding topical, optical or nasal, but including inhaled).
- The Apple Watch is a secondary display of Eversense CGM data and should not be used in place of the primary Eversense CGM display.
The Eversense Data Management System (DMS) is intended for use as an accessory to compatible Eversense CGM products. It is a web based application that may be used to view, analyze, and store glucose information from your Eversense CGM System. The DMS is designed to view the data from your Eversense CGM System in a useful, easy to read format to help you in the management of your diabetes.
You can sync your CGM data wirelessly to the Eversense DMS using the Share My Data feature on the Eversense mobile app. PC users can also upload smart transmitter data via the USB cable provided with your Eversense CGM System.
- You will be uploading the same data whether you sync from the mobile app or use the USB cable.
