Comparing Popular CGM Patches: Freestyle Libre vs. Dexcom

When it comes to CGM patches, choosing the right one can make all the difference in managing your diabetes effectively. Two of the most popular and widely used CGM systems are Freestyle Libre and Dexcom. Both offer continuous glucose monitoring, but there are distinct differences in terms of features, convenience, accuracy, and costs. In this blog, we’ll compare Freestyle Libre CGM patches and Dexcom CGM patches to help you make an informed decision about which one best suits your lifestyle and diabetes management needs.


What Are CGM Patches and How Do They Work?

Before diving into the comparison, let's quickly review what CGM patches are and how they work. A CGM patch is a small adhesive sensor that continuously monitors blood glucose levels in real-time, providing crucial data for diabetes management. These patches contain sensors that measure glucose levels in the interstitial fluid just under the skin and send the data to a receiver or smartphone.

Both Freestyle Libre CGM patches and Dexcom CGM patches offer this functionality, but with some key differences in their features and user experience.


Freestyle Libre vs. Dexcom: Key Differences

1. Accuracy of Readings

When it comes to managing diabetes, accuracy is crucial. Both Freestyle Libre and Dexcom systems provide reliable readings, but there are slight differences in their accuracy.

  • Freestyle Libre: The Freestyle Libre CGM patch measures glucose levels every minute and provides a reading every 15 minutes. It’s known for offering relatively accurate results, especially for day-to-day management.
  • Dexcom: The Dexcom CGM patch generally offers more precise readings with its 5-minute data refresh rate, and it's considered by many to be the gold standard in CGM technology. It’s especially beneficial for people who need constant glucose monitoring due to its continuous, real-time updates.

2. Sensor Wear Time

Another crucial factor in choosing a CGM patch is how long it can be worn before needing replacement. Both systems offer a wear time that is longer than traditional finger-pricking but differ slightly.

  • Freestyle Libre: The Freestyle Libre CGM patches are designed to be worn for up to 14 days, providing a two-week window before replacement is necessary.
  • Dexcom: The Dexcom CGM patches offer a 10-day wear period for the Dexcom G6 model and 7-day wear for the Dexcom G5. Although slightly shorter, many users appreciate the Dexcom system's higher level of precision during this period.

3. User Experience and Convenience

Both Freestyle Libre and Dexcom offer user-friendly systems, but they differ in terms of device compatibility and the method of obtaining glucose readings.

  • Freestyle Libre: The Freestyle Libre CGM patch requires users to scan the sensor with a handheld reader or smartphone to obtain glucose readings. This is a simple, non-intrusive method, but it may not be as convenient for users who need continuous, real-time access to their data.
  • Dexcom: The Dexcom G6 CGM patch continuously sends glucose readings to a smartphone or receiver without the need for scanning, offering more convenience. The ability to view your data in real-time can be a game-changer for those with more active lifestyles or individuals who require consistent monitoring.

4. Cost and Insurance Coverage

Cost is often one of the biggest considerations when choosing a CGM patch. Both Freestyle Libre and Dexcom offer a range of prices, which can vary depending on insurance coverage and location.

  • Freestyle Libre: Generally, Freestyle Libre CGM patches are more affordable, especially in markets like Australia. They offer a more budget-friendly option for those who need regular glucose monitoring but want to keep costs down.
  • Dexcom: While the Dexcom CGM patches tend to be more expensive, many users find the additional cost worthwhile due to the higher level of precision, continuous monitoring, and alerts that the system provides. However, insurance coverage can help mitigate costs for both brands.

Winner: Freestyle Libre (For more affordable options)


5. Features and Alerts

An essential feature for people using CGM patches is the ability to receive alerts for high or low blood sugar levels, which can help prevent dangerous situations.

  • Freestyle Libre: The Freestyle Libre CGM patch offers alerts only when scanning, but it does not have real-time alerts for highs and lows.
  • Dexcom: One of the standout features of Dexcom CGM patches is the built-in alarms that notify you of potential high or low glucose levels in real time, ensuring you stay ahead of any potential issues.
