Are there times when patients will still need to use a meter to make treatment decisions?

You are here

Yes, patients will still need to use a meter to calibrate the Dexcom G5 Mobile every 12 hours. Additionally, there are important exceptions to using the System to make treatment decisions. Please advise your patients that they must use a meter to make treatment decisions in the following situations:

  • Their Dexcom G5 Mobile Receiver or compatible smart device* is not showing both a glucose reading and a directional arrow. Both of these pieces of information must be displayed.
  • Their symptoms or expectations don’t match the CGM reading– if they are experiencing symptoms of hypoglycemia or hyperglycemia, they should use a meter before making a treatment decision.
  • They have taken acetaminophen

The revised instructions allow for CGM-based treatment decisions, but they do not require it. Patients who prefer to use CGM as a complement to SMBG may continue to do so. For some users, it might take a little time to become comfortable with CGM-based treatment decisions. Others may choose to use it at some times (e.g., night) and not at others (e.g., immediately after a new sensor is inserted).
