Dexcom Glucose Systems Receivers Voluntary Recall


On April 11, 2016, the United States Food and Drug Administration (FDA) issued a notice regarding a voluntary recall of continuous glucose monitoring systems manufactured by Dexcom. This recall was issued because the audible alarm may not activate in the receiver piece when low or high glucose levels are detected. Relying on this product for notification of low or high blood sugar could result in serious side effects, including death because the auditory alarm may not sound and users might not be notified of low or high blood sugar.

This may represent a potential health hazard or safety risk to plan members who may be using product affected by this recall.
