Like other CGM systems, people with diabetes can use the Dexcom G7® CGM System to enhance their glucose testing regimen. While this system cannot fully replace finger prick testing, it can greatly reduce patients’ reliance on this testing method.

Like other CGM systems, the Dexcom G7® CGM System allows people with diabetes to easily view their glucose levels. While using this system, you’ll receive updates on your glucose every five minutes without having to deal with finger prick tests.*

What sets the Dexcom G7® CGM System apart from other systems (including Dexcom’s previous CGMs) is the new features it brings to the table. This system is more accurate than any other CGM sold in America,† and it warms up twice as fast as other CGM systems.†† Along with that, you’ll be able to use the Dexcom G7® CGM System with an all-new app.¶

Failure to use the Dexcom G7® Continuous Glucose Monitoring System (G7®) and its components according to the instructions for use provided with your device and available at and to properly consider all indications, contraindications, warnings, precautions, and cautions in those instructions for use may result in you missing a severe hypoglycemia (low blood glucose) or hyperglycemia (high blood glucose) occurrence and/or making a treatment decision that may result in injury. If your glucose alerts and readings from the G7® do not match symptoms, use a blood glucose meter to make diabetes treatment decisions. Seek medical advice and attention when appropriate, including for any medical emergency.
