Dexcom recalls G4 Platinum glucose monitors that may give false high readings when used with hydroxyurea. Affected units include specific sensor kits sold from 2019 onward. No action needed if not using hydroxyurea.
The company identified potential interference from hydroxyurea. Patient use of the anti-neoplastic drug may falsely elevate glucose readings on the Continuous Glucose Monitoring Systems.
Dexcom is recalling its G4 Platinum continuous glucose monitors because they can show falsely high blood sugar levels when used with the chemotherapy drug hydroxyurea. This could lead to incorrect diabetes management decisions if patients rely on the device.
The device may show higher blood sugar levels than actual when hydroxyurea is present. This happens because hydroxyurea interferes with the sensor's ability to measure glucose correctly. Patients might take unnecessary insulin or skip meals based on false high readings.
People with diabetes using Dexcom G4 Platinum monitors who take hydroxyurea may see inaccurate glucose readings. Those not using hydroxyurea are not affected.
Check for model numbers STS-GL-041, STS-RX-041, or STS-MC-004 on the sensor kit packaging. These were sold starting in 2019 with the G4/G5 Sensor Kit 4-Pack.
If you take hydroxyurea, verify your glucose monitor readings may be inaccurate.
No action is needed if you do not take hydroxyurea. The recall only affects users of hydroxyurea.
The affected models are STS-GL-041, STS-RX-041, and STS-MC-004 (G4/G5 Sensor Kit 4-Pack).
The official notice does not mention a fix or remedy. Users should monitor their glucose levels with other methods if taking hydroxyurea.
