FreeStyle Libre 3 Plus
FreeStyle Libre 3 Plus offers up to 15 days of wear per sensor. Check compatibility with your phone and app or FreeStyle Libre 3 reader before buying. Compare the single sensor with the Libre 3 Plus two-pack when budgeting for ongoing use.
FreeStyle Libre 2 Plus
FreeStyle Libre 2 Plus also offers up to 15 days of wear. Abbott confirms compatibility with the FreeStyle Libre 2 reader. Compare the exact display device and features you plan to use in our Libre 2 Plus vs. Libre 3 Plus guide.
FreeStyle Libre 2 and Libre 3
The standard Libre 2 and Libre 3 are distinct from the Plus models. Abbott is discontinuing these standard models; discuss a transition with your care team and check current availability. Our Libre 2 vs. Libre 2 Plus comparison explains why two sensors can represent different supply durations.
Dexcom G7
The Dexcom G7 10-day sensor offers up to 10 days of wear, followed by a 12-hour grace period. It is different from the Dexcom G7 15 Day model. Check the full model name, display-device compatibility, and product instructions before ordering. See our Dexcom G7 vs. Libre comparison for more detail.
How to compare ongoing cash costs
Compare the same model, quantity, and purchase option. A lower price per box does not always mean a lower cost for the same number of days.
- 15-day sensors: two sensors provide up to 30 days of wear.
- Dexcom G7 10-day sensors: three provide up to 30 days, excluding the grace periods from this estimate.
- Pack pricing: check whether a multipack costs less than purchasing the same number of single sensors.
- Additional costs: account for any required reader or receiver, accessories, taxes, and shipping. A calendar month can contain more than 30 days.
Paragon offers cash-pay purchasing without insurance billing. Current prices and availability appear on the product pages. For dated price examples and supply calculations, visit our CGM cost without insurance guide, Libre cash-price guide, or Dexcom G7 cash-price guide.
What to check before choosing a CGM
- Your care plan: ask your healthcare professional which model and monitoring features fit your needs.
- Phone or dedicated display: verify the exact phone, operating system, app, reader, or receiver with the manufacturer. Similar product names do not guarantee compatibility.
- Alerts and daily use: review the model's instructions for alerts, setup, and how you view readings.
- Pump use: if relevant, confirm the exact sensor and pump combination with the manufacturers and your care team.
- Repeat purchases: plan around sensor duration, pack size, and availability.
