Do not ignore symptoms that may be due to low or high blood glucose. If you have symptoms that do not match the Sensor glucose reading or suspect that your reading may be inaccurate, check the reading by conducting a finger stick test using a blood glucose meter. If you are experiencing symptoms that are not consistent with your glucose readings, consult your health care professional.

The FreeStyle Libre Sensor will expire within 14-days, can I still start the Sensor?

Do not use the FreeStyle Libre Sensor past the expiration date. If your Sensor expires during the 14-day wear, start a new Sensor before the Sensor expires.1
