Description
Quick answer: This is a pack of three Dexcom G7 sensors — roughly a one-month supply for the Dexcom G7 continuous glucose monitoring (CGM) system, since each all-in-one, disposable sensor lasts up to 10.5 days (a 10-day wear period plus a 12-hour grace period). The G7 gives automatic readings every 5 minutes with no fingersticks, scanning, or calibration. You’ll need a display device (a compatible smartphone with the Dexcom G7 app, or the Dexcom G7 Receiver), sold separately. A prescription is required. For ages 2 and up.
What’s in this pack?
Three Dexcom G7 sensors. Each sensor is the wearable part of the G7 system, combining the sensor and transmitter into a single disposable unit that’s about 60% smaller than the older G6. Because each lasts up to 10.5 days, a 3-pack covers approximately one month — a convenient resupply quantity so you’re not reordering as often. Once applied, each sensor warms up in about 30 minutes and then continuously measures glucose, sending readings to your display device with customizable high and low alerts and predictive “Urgent Low Soon” warnings.

Is it compatible with my setup?
The G7 sensors require a Dexcom G7 display device — either a compatible smartphone running the Dexcom G7 app, or the Dexcom G7 Receiver. They also work with the Omnipod 5 and Tandem t:slim X2 insulin pumps. Note: the standard Dexcom G7 (10-day) is for ages 2 and up; the separate Dexcom G7 15-Day sensor is a different product cleared for adults 18 and over.
