Learn some tips you can use that can help keep your sensor in place for the full session.
The Dexcom G7 Continuous Glucose Monitoring (CGM) System has a sensor patch containing medical-grade, pressure-sensitive, acrylic-based adhesive designed to keep your sensor on for the full 10-day wear period. But we know that a lot can happen over 10 days and your sensor could fall off!
Whether you bump into something that causes your Dexcom G7 CGM sensor to fall off or you snag the sensor on your shirt or a towel, it’s possible that your sensor can fall off before your sensor session is up.
Below you will find some tips on how to keep Dexcom G7 CGM sensor from falling off and keep the sensor in place for the full session!
1. Sensor site preparation
Extra care and preparation when selecting your sensor site can help the adhesive work as designed.
- Site prep: Sensor site should be flat, clean, and completely dry before you insert the sensor. There should be some fat under the skin at the sensor site.
- Placement: The patch stays on best when it isn't where your skin folds.
- Avoid hair: Apply the patch to areas without much hair. If needed, shave the site with electric clippers.
- Old adhesive: Remove any adhesive residue from previous sensors. Consider using a body oil or adhesive remover for skin (such as Uni-solve, Detachol, or Tac Away).
- Switch sites: Don’t use the same sensor site twice in a row.
- Keep skin healthy: Consider moisturizing your skin between sensor sessions to avoid dry skin, but don’t use moisturizer on the sensor site the day you insert the sensor.
2. Adhesive patch care
- First 12 hours: The longer you keep it dry and sweat-free in the first 12 hours, the longer it may stick to your skin.
- Keep dry: When your sensor gets wet, gently pat it dry as soon as you can.
- Maintenance: If the sensor patch starts to peel around the edges, trim the peeled parts and put on medical tape.
- Smooth patch: Get some help applying your overpatch to ensure a smooth application without wrinkles.
