Dexcom recalls G4/G5 glucose monitors that may give false high readings when patients take hydroxyurea. Affected units include specific sensor kits sold with model numbers STS-GL-041, STS-RX-041, and STS-MC-004.
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 and G5 continuous glucose monitoring systems because hydroxyurea medication can cause false high glucose readings. This could lead to incorrect diabetes management decisions if users rely on the device without knowing the readings are inaccurate.
Hydroxyurea, an anti-neoplastic drug, can interfere with the glucose monitoring system's sensors, causing false high readings. This may lead to incorrect diabetes management decisions if users rely on the device without knowing the readings are inaccurate.
People with diabetes who use Dexcom G4 or G5 glucose monitors and take hydroxyurea medication are most at risk. The recall affects specific sensor kits sold with model numbers STS-GL-041, STS-RX-041, and STS-MC-004.
Check for model numbers STS-GL-041 (4-pack retail), STS-RX-041 (4-pack retail), or STS-MC-004 (4-pack Medicare) on the sensor kit packaging. These models were sold with the specific lot numbers listed in the recall.
If you take hydroxyurea and see consistently high glucose readings, contact Dexcom for assistance.
