Two separate 2025 FDA notices involve Dexcom continuous glucose monitors. One is about certain handheld receivers whose speakers may fail. The other is about older versions of the Dexcom G7 and ONE+ apps. They involve different parts, different products and different fixes. Here is how to tell which one, if either, applies to you.
Two notices, two parts
A Dexcom system has a sensor worn on the body. Readings from the sensor can appear on a handheld receiver, on a phone or watch app, or on both. The two notices cover different parts:
- The receiver recall covers certain Dexcom G6, G7, ONE and ONE+ receivers. The problem is the speaker.
- The app correction covers older versions of the Dexcom G7 and ONE+ apps. The problem is a missing alert.
The FDA identified each one as the most serious type of recall. Neither notice lists Dexcom sensors as affected products.
The receiver recall
A receiver is a small handheld device that shows glucose readings and can sound alerts. The FDA says certain Dexcom G6, G7, ONE and ONE+ receivers have a speaker problem. The receiver may not make a sound when it should warn about high or low glucose. The Dexcom ONE and ONE+ receivers are sold only outside the U.S.
A person who counts on that sound could miss a warning. The FDA says a missed alert could lead to serious harm, such as seizures, loss of consciousness or death.
The FDA notice, last updated July 17, 2025, says there had been at least 56 reported injuries and no reported deaths. These are reports, not findings that the receiver caused each injury.
This recall is a removal. Dexcom sent affected customers an updated notice on June 9, 2025. The FDA gives these steps:
- Visit dexcom.com/checkreceiver to see if your receiver is affected.
- If it is, call Dexcom Technical Support at 1-844-478-1600 to ask for a free replacement.
- Whether or not your receiver is affected, test its speaker every time you charge it.
- If the speaker does not beep during the test, contact Dexcom right away.
- Make sure everyone who relies on the receiver for alerts knows about the problem.
The app correction
The FDA says these app versions are affected:
- Dexcom G7 app for Android, iOS and watchOS, version 2.8.0 or earlier
- Dexcom ONE+ app for Android and iOS, version 1.4.0 or earlier
The problem shows up when the transmitter on the sensor fails. The app should show a “Sensor Failed” alert. Instead, the affected versions may end the session and stop showing glucose readings without warning. A person might not notice that readings have stopped.
The FDA notice, last updated September 15, 2025, says there were no reported injuries or deaths.
This is a correction, not a removal. Dexcom told customers about it on July 24, 2025. The app update was required, and the older versions stopped working after August 20, 2025. If you use one of these apps, check your app store to make sure it is up to date. Dexcom Technical Support is at 1-844-478-1600.
A third, separate notice
The FDA’s recall list also includes a separate correction for one version of the Dexcom G6 app for Android, version 1.15.0. The FDA says that version could shut down without warning. The FDA’s notice says all affected devices have been updated and that the version stopped working after October 6, 2025.
Which one applies to you?
- If you use a Dexcom receiver, check the receiver recall.
- If you use a Dexcom app, check which app and version you have.
- If you use both, check each one on its own. One notice does not tell you about the other.
If you are unsure, contact Dexcom or your health care provider. Do not stop using your CGM or change how you treat diabetes without talking to your provider.
What about lawsuits?
As of September 27, 2026, we have not found a public settlement or jury verdict involving these Dexcom notices in the federal court records we reviewed. A recall alone does not prove that a device caused an injury. Whether someone has a claim depends on the facts, the records and the law that applies. No result can be promised.
