Short summary: Dexcom says two lots of Dexcom G7 sensors that had been marked as scrap and intended for destruction were stolen during the destruction process and later sold through unauthorized channels. The two lot numbers to check are 1725204004 and 1725069002.
Safety note: This is not a warning about every Dexcom G7 sensor. It applies to the specific lot numbers listed in Dexcom and regulator notices. If you have a sensor from one of these lots, follow the official instructions, use an alternative glucose monitoring method if needed, and contact Dexcom support or your diabetes care team if you are unsure what to do.
Key takeaways
- Check Dexcom G7 sensor lot numbers 1725204004 and 1725069002.
- Dexcom says the affected sensors were stolen after being marked for destruction and were sold through unauthorized channels.
- Dexcom says people with affected sensors should not use them and should contact Dexcom for a replacement.
- If your glucose symptoms do not match a CGM reading, use a backup blood glucose meter according to your usual care plan.
What happened?
On May 26, 2026, Dexcom announced that certain Dexcom G7 sensors had been designated as scrap and intended for destruction, but were stolen during the destruction process and sold through unauthorized channels. Dexcom said many of the stolen sensors sold in the United States were traced to Pharmsource, LLC, which Dexcom says is not an authorized Dexcom distributor.
Dexcom said it began notifying people who may have received affected sensors. Regulators and diabetes organizations in Australia also published recall or market-action notices for the same two lot numbers.
The two lot numbers to check
Check the lot number on your Dexcom G7 sensor packaging. The affected lot numbers named in the notices are:
| Lot number | What the notices say |
|---|---|
| 1725204004 | Dexcom described a sterilization-related concern for this lot, which may increase the risk of skin infection. |
| 1725069002 | Dexcom described an elevated internal testing failure rate for this lot, which may increase the risk that a sensor does not provide readings. |
The Australian Therapeutic Goods Administration also warned that affected products may carry risks including skin infection, inaccurate or lost readings, and missed detection of low or high glucose. The TGA notice says only the specified lot numbers are affected.
What users should do now
- Check the lot number. Look at the sensor package and compare it with the two lot numbers above.
- Do not use an affected sensor. Dexcom and regulator notices advise affected users to stop using sensors from these lots.
- Use a backup method if needed. If you cannot use your sensor, use another unaffected sensor or a blood glucose meter according to your usual diabetes plan.
- Contact Dexcom for replacement guidance. Dexcom says affected users should contact Dexcom support for replacement help.
- Be cautious with unexpected readings. If symptoms do not match the CGM number, confirm with a blood glucose meter if that is part of your care plan.
What if you already used one?
Dexcom said it had not received reports of serious adverse events linked to the affected stolen lots at the time of its announcement. That does not mean there is no risk. If you used a sensor from one of these lots and noticed skin irritation, signs of infection, missing readings, or readings that did not match how you felt, contact your healthcare professional or Dexcom support.
Seek urgent medical help if you have symptoms of severe high or low glucose, symptoms of diabetic ketoacidosis, rapidly worsening illness, or signs of a serious skin infection. This article cannot tell you how to adjust insulin or other diabetes medicines.
What this does not mean
This recall information should not be read as a blanket warning about all Dexcom G7 sensors. The notices reviewed for this article identify two specific lot numbers. People using other Dexcom G7 sensors should continue following their usual diabetes plan unless Dexcom, a regulator, or their healthcare professional gives different advice.
Evidence and source summary
Dexcom reported the theft and unauthorized resale, named the two affected lot numbers, and said affected users should not use sensors from those lots. The TGA, NDSS, and Diabetes Australia notices support the same lot-number check and add regulator-facing safety language about possible infection, inaccurate or lost readings, and missed detection of hypoglycemia or hyperglycemia. MedTech Dive independently reported the same core facts and identified the unauthorized-distribution concern.
Practical takeaway
If you use Dexcom G7, check whether your sensor packaging shows lot number 1725204004 or 1725069002. If it does, follow Dexcom or regulator instructions, avoid using the affected sensor, and use an alternative glucose monitoring method if needed. Do not make medication changes based on this news article alone.
