Dexcom G7 Stolen Sensor Safety Notice
Stolen Dexcom G7 Sensors Are Out There. Here's the One Thing to Check.
Most people reading this are completely fine. But there are two specific G7 lot numbers worth thirty seconds of your time — so let's go through it together.
Two G7 lot numbers are affected
If you have unused Dexcom G7 sensors, look at the lot number printed on the box and packaging. If it matches either number below, do not use those sensors.
Not properly sterilized — increased risk of skin infection.
Elevated failure rate — may give no glucose readings at all.
- Stop using any sensor from those two lots.
- Call Dexcom in the US at 1-844-478-1600 to get free replacements.
- Check the official page for step-by-step instructions on finding your lot number: dexcom.com/theft-check
Outside the US? This issue is US-focused, but Dexcom is adding region-specific resources — check the theft-check page for your country's instructions.
Open the Dexcom Theft-Check page →Here's what actually happened, who it affects, and how to think about it without losing your mind.
What happened
This is not a manufacturing defect, and it's not a routine recall. It's theft.
When Dexcom makes sensors, some don't pass their quality checks. Those get flagged as "scrap" and sent to an outside vendor to be destroyed and recycled. That's normal — every manufacturer does some version of this. The problem is that someone stole certain lots of those scrapped G7 sensors during the destruction process and sold them through a company called Pharmsource, LLC, which is not an authorized Dexcom distributor.
So these are sensors that Dexcom had already decided were not good enough to sell, then someone diverted them and put them back into the supply chain anyway. Dexcom caught it through its own quality and accounting reviews, traced the sales back to the source, and is now notifying people directly and working with the FDA and other authorities.
Who is — and isn't — affected
This is the part that should bring your blood pressure back down. The vast majority of G7 users are not impacted at all.
You're almost certainly fine if you get your sensors the normal way — through a major pharmacy retailer (think the big chains), through your insurance, or through a medical distributor that buys from Dexcom's authorized distributors. Educational samples are not affected either.
You'll want to look more carefully if your sensors came through a smaller independent pharmacy or a DME (durable medical equipment) supplier, since Pharmsource sold to some of those. If that's you, check your lot numbers against the two above. Dexcom also publishes its list of authorized US distributors at dexcom.com/dexcom-suppliers.
The reassuring note from Dexcom: as of their announcement, they had not received reports of any severe adverse events tied to the stolen product. But the two risks are real — a sensor that wasn't sterilized properly is an infection concern, and a sensor with a high failure rate can quietly leave you with no data when you're counting on it. Neither is something to gamble on when a replacement is free.
What to do, in order
Don't overthink this. Walk through it once and you're done:
1. Find your lot numbers
Pull out any unused G7 sensors and look at the lot number on the outer box and the individual packaging. You're checking for 1725204004 and 1725069002.
2. If you don't have either lot
You're done. Carry on. Nothing about your sensors changed because of this news.
3. If you do have an affected lot
Set those sensors aside, don't insert them, and call Dexcom at 1-844-478-1600 for free replacements. Use the official dexcom.com/theft-check page to confirm and get the exact steps. If you've already worn one and you have any sign of skin irritation or infection at the site — redness, swelling, warmth, pus — loop in your doctor, not just Dexcom.
How I'd think about this
A few of you saw the word "stolen" next to "sensor" and your stomach dropped. I get it. When you live with a device attached to your body that's helping you make insulin decisions all day, anything that threatens trust in that device feels personal. So let me say the calm thing plainly:
This is a narrow, traceable problem with a free fix. Two lot numbers. A phone call. Done. The thing that protects you here isn't panic — it's the thirty seconds it takes to read a number off a box. Competence beats fear every time, even when the fear is about supply chains instead of blood sugar.
If there's a lasting takeaway, it's a quiet one: where you get your supplies matters. Authorized channels exist for a reason, and "I found it cheaper somewhere unofficial" is exactly the gap that let this happen. That's not a reason to be anxious — it's just a reason to know your sources.
And give Dexcom this much: they found it themselves, traced it, and went public instead of hoping no one noticed. That's the version of accountability you actually want from a company making something you stick to your body.
Quick recap: Two G7 lots — 1725204004 (sterilization) and 1725069002 (failure rate) — were stolen as scrap and sold through an unauthorized vendor. Check your boxes. If you have either lot, stop using them and call Dexcom at 1-844-478-1600 for free replacements. Everyone else: nothing to do.
