Overview

• On June 22, the Agencia Española de Medicamentos y Productos Sanitarios flagged a fault in Dexcom One+ iOS v1.2 that can halt glucose value updates and disable hypoglycemia and hyperglycemia alerts.
• Users report that since June 12 the app’s trend graphs have frozen or disappeared, raising risks of undetected glucose excursions and potential misinformed treatment decisions.
• The AEMPS advises all Dexcom One+ iOS users to look for an in-app notification, verify they are not on version 1.2 and download the latest release from the Apple App Store.
• Dexcom One+ iOS is part of a continuous glucose monitoring system approved for users over age two, including pregnant women, and intended to replace capillary blood glucose tests.
• Patients who did not receive the company’s notification are instructed to contact Dexcom, Inc. directly for assistance in restoring accurate glucose monitoring.
