Product Name: Dexcom G4 Platinum Continuous Glucose Monitoring System

PMA Applicant: Dexcom Inc.

Address: 6340 Sequence Drive

Approval Letter: http://www.accessdata.fda.gov/cdrh_docs/pdf12/p120005a.pdf

What is it? The Dexcom G4 PLATINUM Continuous Glucose Monitoring (CGM) System continuously measures and displays glucose values. In addition to reporting glucose values every five minutes, the system reports trending information in real-time for up to seven days.

How does it work? The G4 PLATINUM CGM System includes three components: a sensor, transmitter and receiver. The glucose sensor is a small wire that is inserted under the skin of the abdomen and measures glucose values in the fluid between the body’s cells (interstitial fluid). The glucose values are sent through the transmitter to the hand-held receiver, where they are displayed for the user.

When is it used? The Dexcom G4 PLATINUM CGM System is a glucose monitoring device used to detect trends and tracking patterns in persons (age 18 and older) with diabetes. The system is intended for single patient use and requires a prescription.

The Dexcom G4 PLATINUM CGM System aids in the detection of episodes of high blood glucose (hyperglycemia) and low blood glucose (hypoglycemia), to help with both short-term and long-term therapy adjustments, which may minimize these highs and lows in blood glucose. Interpretation of the Dexcom G4 PLATINUM CGM System results should be based on the trends and patterns seen with several consecutive readings over time.

The Dexcom G4 PLATINUM CGM System does not replace the information obtained from a standard home blood glucose meter but rather, it is used to complement the information obtained from the blood glucose meter.

What will it accomplish? People with diabetes can use the tracking and trending glucose information to help understand patterns in their glucose levels, and be alerted when glucose values are approaching potentially dangerously high (hyperglycemic) and/or dangerously low (hypoglycemic) levels. When used along with a blood glucose meter to obtain a more accurate reading of actual blood glucose levels, the Dexcom G4 PLATINUM CGM can also help people with diabetes make long-term adjustments to their treatment plan to keep blood glucose levels in a safe range.

When should it not be used?
The Dexcom G4 PLATINUM CGM System sensor, transmitter, and receiver should be removed before Magnetic Resonance Imaging (MRI), Computed Tomography (CT) scan, or diathermy treatment. The Dexcom G4 PLATINUM CGM System has not been tested during MRI or CT scans or with diathermy treatment. The magnetic fields and heat could damage the device so that it might not display sensor glucose readings or provide alerts, and a low or high glucose value may be missed.

Taking medications with acetaminophen (such as Tylenol) while wearing the sensor may falsely raise your sensor glucose readings. The level of inaccuracy depends on the amount of acetaminophen active in your body and may be different for each person.
