On May 27, 2026, Dexcom, Inc. began a recall of two lots of Dexcom G7 sensors that had been designated as scrap and were stolen during the destruction process.[1] The FDA posted the recall on June 24, 2026, as a Class 2 (Class II) device recall, recall number Z-2574-2026.[1] As of the FDA record we read on October 15, 2026, its status was "Open, Classified".[2]
What the FDA record says
The recall covers the Dexcom G7 US Retail Sensor/Transmitter 1-pack, model or catalog number STP-AT-012.[1] According to the FDA record, the sensors were later sold to pharmacies and distributors by Pharmsource, LLC.[1]
The two lots had been pulled for different reasons. Lot 1725204004 was set aside for destruction because the sensors were not properly sterilized and carry an increased risk of skin infection if used.[1] Lot 1725069002 was set aside because of an increased risk of no sensor readings or of sensor inaccuracy. The record says that inaccuracy includes the potential for a missed high glucose (hyperglycemic) event or incorrect treatment decisions that can result in patient injury.[1] The record adds that the unknown storage and handling conditions during distribution may present additional risk.[1] The FDA listed the cause as "Nonconforming Material/Component".[2]
The FDA record gives no count of affected sensors. Dexcom told the FDA it has no distribution records for this product because its release was unauthorized.[1] Instead, the company said it could see sensor session starts for the affected lots through Dexcom G7 app user performance data. Those data showed session starts for lot 1725204004 in the United States, and for lot 1725069002 in the United States and 23 other places the record lists, including Canada, Japan and the United Kingdom.[1]
According to the record, Dexcom issued a press release on May 26 and 27, 2026, and sent an "URGENT: MEDICAL DEVICE CORRECTION NOTIFICATION" to customers and the public.[1]
What this means for you
Dexcom's instructions, as the FDA recorded them, are short. If you have an affected sensor, stop using it and dispose of it.[1] Contact Dexcom Technical Support at 1-844-478-1600 with questions or to ask for a no-cost replacement.[1] Keep a record of the affected serial number, because Dexcom requires it to confirm the no-cost replacement.[1]
Dexcom's notice also says that if you do not have an unaffected G7 sensor, use a blood glucose meter for treatment decisions until the replacement arrives.[1] It tells users to contact a healthcare provider about redness, swelling or pain at the insertion site, which can be symptoms of infection.[1] For any other question about your treatment or supplies, talk to your care team or pharmacist.
The notice has a separate step for independent pharmacies. Those that bought G7 sensors from Pharmsource, LLC should check their inventory, dispose of any product from the listed lots, and send related questions to [email protected].[1]
How to check your lot number
The FDA lists exactly two affected lot numbers, both under UDI-DI 00386270004109:[2]
- 1725204004
- 1725069002
Dexcom's notice says to check the lot number on the G7 sensor's outer box and compare it with those two numbers. If it matches, the sensor is affected.[1] You can also compare against the list in the FDA recall record.[1]
Dexcom's notice also points to a serial number look-up at www.dexcom.com/theft-check for checking whether a current or unused sensor is affected.[1] Dexcom says the G7 serial number is a 12-digit number. It appears after the label (21) on the side of the sensor box and on the back of the applicator.[3] In the Dexcom G7 app it is under Connections > Sensor, labeled SN, and in the receiver under Menu > Information > Sensor > Session info.[3]
We will add a dated update to this post if Dexcom or the FDA changes the scope of the recall or closes it.
