If you already use the Dexcom G6 continuous glucose monitor (CGM), you may already know that Dexcom will stop producing G6 sensors after July 1, 2026. The company is encouraging all users to switch to the <\/span>Dexcom G7<\/span><\/a>\u00a0 model to prepare for the transition. It can be helpful to understand the differences between Dexcom G6 and G7 before switching. This way, users can feel confident and prepared for any adjustments they need to make to their glucose monitoring routine. Here’s what to know about the Dexcom G6 and G7, and how to talk to your healthcare provider about switching.<\/span><\/p>\n

Dexcom G6 vs. G7: Key differences<\/span><\/h2>\n

“CGMs are recommended for patients who need real-time glucose trends, including those with type 1 diabetes, insulin-treated type 2 diabetes, frequent hypoglycemia, or hypoglycemia unawareness,\u201d explains <\/span>Eve Elizabeth Pennie<\/span><\/a>, MD, physician and epidemiologist at Drugwatch. \u201cThey help track patterns, guide treatment decisions, and improve overall glycemic control,\u201d she says.\u00a0<\/span><\/p>\n

The G6 and G7 are both CGMs made by Dexcom. The G7 has updated hardware, sensors, and software compared to the G6. Dexcom also offers a\u00a0 G7 15 Day version, which has a <\/span>15-day wear time<\/span><\/a> compared to the standard G7\u2019s 10-day lifespan. Read on for more on these key differences.<\/span><\/p>\n

Warm-up time<\/span><\/h3>\n

One of the biggest differences between the G6 and G7 is the <\/span>warm-up time<\/span><\/a>, which is the time between inserting a sensor and getting a reading. The G6 model requires two hours to warm up, while the G7 can produce a reading in as little as 30 minutes. A shorter warm-up time means less time without glucose data between sensor changes, which can matter for those who need to monitor their glucose closely. For G6 users, that wait can feel like \u201c2 hours of staring at nothing,\u201d says <\/span>Kiara DeWitt<\/span><\/a>, registered nurse (RN) and CEO at InjectCo in Dallas, Texas.<\/span><\/p>\n

Accuracy and performance<\/span><\/h3>\n

The accuracy of a CGM is measured in mean absolute relative difference, or MARD. A lower MARD means that the sensor’s readings are closer to laboratory blood glucose numbers. Location of the sensor, as well as the device generation, can make a difference. In one Dexcom study comparing the G5, G6, and G7 systems, G7 sensors placed on the upper arm had a <\/span>lower MARD than older models<\/span><\/a>. The upper arm-placed G7 had a MARD of 8.2%, compared to 9.1% for abdomen-placed G7, 9.9% for abdomen-placed G6, and 9.0% for abdomen-placed G5.\u00a0<\/span><\/p>\n

App and alerts<\/span><\/p>\n

\u201cCGMs connect to smartphone apps that display real-time readings, trend arrows, and alerts for high or low glucose. Apps can also share data with caregivers or clinicians, so patients should understand how to interpret trends rather than focusing on single values,\u201d Dr. Pennie says.<\/span><\/p>\n

The Dexcom G7 has a new mobile app that’s separate from the G6 app and isn’t backwards compatible. Both apps work with <\/span>Dexcom Clarity<\/span><\/a>, which analyzes your glucose readings to generate trends and reports to help you and your healthcare provider manage your blood glucose levels.\u00a0<\/span><\/p>\n

The newer Dexcom G7 model also has more advanced predictive alert features compared to the G6, including the option to delay the first high alert, and 24-hour backfilling for missed sensor readings due to connection lapses.\u00a0<\/span><\/p>\n

The alerts and settings may take some getting used to, according to DeWitt. \u201cWhen you switch models, you will need to relearn the sounds of alerts and trend arrows. Each model has their own calibration nuances as well. Allow 5-7 days for your body to adjust to a new CGM,\u201d she says.<\/span><\/p>\n

Wear time and grace period<\/span><\/h3>\n

CGM sensors need to be replaced periodically to keep readings accurate. The time a sensor can be worn before it needs to be replaced is called the wear time, and most sensors have a grace period that lets you continue getting readings for a short time after the sensor technically expires.\u00a0<\/span><\/p>\n

Both the G6 and G7 have a 10-day wear time, but Dexcom also offers the G7 15-Day, which extends wear time to 15 days. The Dexcom G7 has a 12-hour grace period, while the G6 does not have one.\u00a0<\/span><\/p>\n

Size<\/span><\/h3>\n

One of the most noticeable differences between the Dexcom G6 and G7 models might be <\/span>the size<\/span><\/a>. According to the manufacturer, the G7 is 60% smaller than the G6, about the size of three stacked quarters. The G7 also combines the sensor and transmitter into a single unit, while the G6 uses separate sensor and transmitter components.\u00a0<\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n

Benefits of switching to Dexcom G7<\/span><\/h2>\n

Compared to the G6, the Dexcom G7 is smaller, has a faster warm-up time, and has the option for a longer wear period with the G7 15 Day. The smaller size makes the G7 more discreet under clothing and more comfortable for users to wear. In addition, the Dexcom G7 is FDA-approved for use during pregnancy, while the G6 is not.<\/span><\/p>\n

The G6 has separate sensor and transmitter components that need to be connected for the device to work, but the G7 combines the two, which can make it easier for users to insert new sensors.<\/span><\/p>\n

Finally, those who appreciate more control over their CGM alerts may prefer the G7’s app. It can create day\/night alert profiles, delay the first high alert (helpful for after-meal glucose spikes), and switch to vibrate-only mode for up to six hours.<\/span><\/p>\n

These upgrades are part of a broader advancement in CGM technology. “CGM technology is actually advancing rapidly,” DeWitt says. “The options we have today may seem primitive in two to three years when the next generation models are released.”<\/span>\u00a0<\/span><\/p>\n

Potential drawbacks of switching from Dexcom G6 to G7<\/span><\/h2>\n

There are a few practical points to consider before switching from the Dexcom G6 to the G7. If you use an automated insulin delivery (AID) system, the G6 and G7 are compatible with different pumps, so switching sensors may affect which pump you can use. It’s best to check<\/span> Dexcom’s pump partnerships<\/span><\/a> and contact your healthcare provider or<\/span> Dexcom Support<\/span><\/a> before making the switch.\u00a0<\/span><\/p>\n

The <\/span>G6<\/span><\/a> and G7 apps are also compatible with different mobile devices, so it’s worth<\/span> checking whether your phone supports the G7 app<\/span><\/a> before making the switch.\u00a0<\/span><\/p>\n

Though coverage is generally the same for both Dexcom G6 and G7 models, it might not always be automatic. Some insurance plans may require documentation or purchase from an authorized provider, which can add some time to the process. In the case of<\/span> Medicare coverage<\/span><\/a>, patients will have to get the device from a Medicare-authorized distributor.\u00a0<\/span><\/p>\n

How to switch from Dexcom G6 to G7<\/span><\/h2>\n

Switching from the Dexcom G6 to the G7 can include the following steps:<\/span><\/p>\n

    \n
  1. Check device and pump compatibility:<\/b> If you use an AID system or connected pump, confirm G7 compatibility with Dexcom before making any changes.<\/span><\/li>\n
  2. Talk to your healthcare provider:<\/b> Your provider can help you determine whether the G7 or G7 15 Day is the best fit based on your lifestyle, age, and condition.<\/span><\/li>\n
  3. Get a new prescription:<\/b> The G7 requires a new pharmacy prescription for anyone switching from G6 to G7.<\/span><\/li>\n
  4. Confirm your insurance coverage:<\/b> Contact your insurance provider to verify coverage before placing your order, in case you need prior authorization or other documentation for approval. If you don\u2019t have insurance coverage, you can use a SingleCare coupon to reduce the cost of a G7 sensor.\u00a0<\/span><\/li>\n
  5. Order your G7 supplies:<\/b> Reach out to your pharmacy or distributor to order your Dexcom G7 sensor and accessories.<\/span><\/li>\n
  6. Update or upgrade your G6 receiver (if eligible):<\/b> If you have a G6 receiver, you might be able to <\/span>upgrade it to a G7-compatible receiver<\/span><\/a> from the Dexcom Clarity website.<\/span><\/li>\n
  7. Download and install the Dexcom G7 app.<\/b><\/li>\n
  8. Apply your first G7 sensor<\/b> and follow the G7 app\u2019s instructions to pair with your smartphone and configure your alert preferences.\u00a0<\/span><\/li>\n<\/ol>\n

    How much does Dexcom G7 cost?<\/span><\/h2>\n

    The <\/span>average cost for a three-pack of G7 sensors<\/span><\/a> (three sensors with a 10-day wear time, a 30-day supply) is <\/span>$579 without insurance<\/span><\/a>. In comparison, the average cost for a three-pack of G6 sensors is <\/span>$560 without insurance<\/span><\/a>, though you\u2019ll also need to factor in $366 every 90 days for the additional transmitter component. With a SingleCare coupon, a month\u2019s supply of G7 sensors can cost $332, and G6 sensors can cost $325.<\/span><\/p>\n

    Dexcom also offers a Patient Assistance Program for those with limited income and no insurance coverage. Talk to your healthcare provider to discuss which savings options apply to you.\u00a0<\/span><\/p>\n\n\n\n\n\n\n\n\n

    Bottom line<\/span><\/h2>\n

    After <\/span>July 1, 2026<\/span><\/a>, Dexcom will no longer produce new G6 sensors, so switching to the G7 model will be necessary for most patients who want to continue monitoring their blood glucose. It\u2019s best to start the conversation about switching with your healthcare provider as soon as you can, so you have time to confirm details like pump compatibility, update your prescription, and sort out insurance coverage without disrupting your monitoring.<\/span><\/p>\n

    If you don\u2019t have insurance coverage, a SingleCare coupon can help you save up to 43% on the cost of a G7 sensor. Enter your ZIP code on the Dexcom G7 coupon page to see prices at pharmacies near you.\u00a0<\/span><\/p>\n

    Expert takeaway<\/span><\/h2>\n

    \u201cIn my experience, CGMs like the Dexcom G7 are powerful tools that help protect patients from the short-term hazards and long-term complications of diabetes,\u201d relates Chad Shaffer, MD, a member of the SingleCare Medical Board, \u201cand continuing to deploy the most up-to-date software and hardware is worth considering, even if it takes some getting used to.\u201d<\/span><\/p>\n

    Frequently asked questions<\/span><\/h2>\n

    Do I need to switch from Dexcom G6 to G7?<\/span><\/h3>\n

    Yes. After July 1, 2026, Dexcom will no longer produce G6 sensors. While you can keep using any G6 sensors you still have until your supply runs out or expires, you’ll need to switch to the G7 to continue monitoring afterward.\u00a0<\/span><\/p>\n

    Do I need a new prescription for Dexcom G7?<\/span><\/h3>\n

    Yes, you will need a new prescription for Dexcom G7 even if you already have a current G6 prescription.\u00a0<\/span><\/p>\n

    What if I\u2019m switching from Dexcom G6 to G7 with Omnipod 5?<\/span><\/h3>\n

    Omnipod 5 is <\/span>compatible with both Dexcom G6 and G7<\/span><\/a> models. But only the newer Omnipod 5 Pods work with the G7. You won’t need a new prescription, but you may need to wait for your next Pod order to receive G7-compatible Pods. Check with Dexcom Support before switching.\u00a0<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
