How can I avoid irritated or sensitive skin caused by the Dexcom G6 sensor adhesive?

If you have irritated or sensitive skin please work with your healthcare professional (HCP).
This is a summary of two clinical articles published by clinicians independent from Dexcom based on their knowledge and experience.*† Dexcom has not tested these approaches nor do we endorse these specific approaches. For detailed step-by-step instructions on how to use the Dexcom G6 Continuous Glucose Monitoring (CGM) System, please refer to the user guide.
Do you have skin irritation at the sensor site of your diabetes monitor or sensitive skin? These considerations, skin barriers, and professional tips may help. Remember what works best for one person may not work best for everyone. You may need to try several different products or methods when using a CGM and you have sensitive skin for you and your HCP to figure out what works best.
General consideration*
  • Clean skin with oil-free, antimicrobial soap and dry thoroughly1,2
  • Gentle exfoliation recommended for oily skin2
  • Trim hair with dry razor if needed3
  • Do not use any lotion or oil containing moisturizer where you insert the sensor
  • Do not insert CGM sensor immediately after a shower/bath or in a steamy bathroom—minimize humidity with hairdryer or application in a dry environment2
  • Solid or spray antiperspirant (unscented) may help with skin prone to sweating. Create an empty oval on the skin with the antiperspirant, wait 10–15 min. Insert CGM sensor on clean skin in centre of oval.1,2
Barrier Films*
  • Barrier films may help prevent mild skin irritation or rash from adhesives4
  • Create an oval on the skin with the barrier film and insert CGM sensor on clean skin in centre of oval
  • Let barrier film dry completely before placing CGM sensor1,4
  • May apply one layer or a second after first layer has drieda

  • When used as a barrier, patches/bandages must be placed underneath the sensor adhesive patch2,5,6
  • Place on skin before sensor adhesive
  • Cut an oval in the patch/bandage and insert CGM sensor on clean skin in the center of the oval

Failure to use the Dexcom G6 Continuous Glucose Monitoring System (G6) and its components according to the instructions for use provided with your device and available at dexcom.com/safety-information 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 G6 do not match symptoms or expectations or you’re taking over the recommended maximum dosage amount of 1000mg of acetaminophen every 6 hours, use a blood glucose meter to make diabetes treatment decisions. Seek medical advice and attention when appropriate, including for any medical emergency.
