Device Use

The Dexcom Continuous Glucose Monitoring Systems are used to monitor the blood sugar (glucose) level of adult and pediatric patients with type 1 or type 2 diabetes.

Reason for Recall

Dexcom Inc. is recalling the Continuous Glucose Monitoring Systems because the audible alarm may not activate in the receiver piece when low or high glucose levels (hypoglycemia or hyperglycemia) are detected.

Relying on this product for notification of low or high blood sugar could result in serious adverse consequences, including death as the auditory alarm may not sound and users might not be notified of low or high blood sugar.

Who May be Affected
  • All patient groups using the Dexcom Continuous Glucose Monitoring Systems to monitor their blood glucose levels
  • Health care providers who prescribe these monitoring systems to patients in their care

On February 23, 2016, Dexcom Inc. sent an Important Customer Notification Letter with the following instructions to test the audio alert on the receiver:

  • press the center button on your receiver to access the Main Menu
  • scroll down to Profiles
  • select Profiles
  • scroll down to Try It
  • select Try It
  • scroll down to 55 Fixed Low
  • select 55 Fixed Low
  • verify that you receive vibrations first (vibratory portion of alarm), followed by beeps (audible portion of alarm).

Customers should contact Dexcom at their free hotline number: (844) 607-8398, if the audio alert does not work properly.
