1. May 27, 2026Open, Classified

   Certain lots of Dexcom G7 sensors originally designated as scrap and intended for destruction were stolen during the destruction process. The sensors were later sold to pharmacies and distributors by Pharmsource, LLC. Lot 1725204004 were designated for destruction because the G7 sensors were not properly sterilized and have an increased risk of skin infection if used. Lot 1725069002 were designated for destruction due to an increased risk of having no sensor readings available or experiencing sensor inaccuracy that includes the potential for missed detection of a hyperglycemic event or incorrect treatment decisions that can result in patient injury, including medical intervention to prevent permanent injury or impairment. Additionally, due to the unknown storage and handling and storage conditions these sensors may have undergone during the distribution, these sensors may present additional risk.
