What to Know about X-Rays
• The Sensor should be removed prior to exposing it to an X-ray
machine. The effect of X-rays on the performance of Bigfoot Unity
has not been evaluated. The exposure may damage the Sensor
and may impact proper function of the device to detect trends and
track patterns in glucose values during the wear period.
When to Remove the Sensor
• If the Sensor is becoming loose or if the Sensor tip is coming out
of your skin, you may get no readings or unreliable readings, which
may not match how you feel. Check to make sure your Sensor has
not come loose. If it has come loose, remove it, apply a new one,
and contact Bigfoot Customer Care at (551) 244-3668.
• If you believe your glucose readings are not correct or are
inconsistent with how you feel, perform a blood glucose test on
your finger to confirm your glucose. If the problem continues,
remove the current Sensor, apply a new one, and contact Bigfoot
Customer Care at (551) 244-3668.
3.8 Interfering Substances
Taking ascorbic acid (vitamin C) supplements while wearing the Sensor
may falsely raise Sensor glucose readings. Taking more than 500 mg
of ascorbic acid per day may affect the Sensor readings which could
cause you to miss a severe low glucose event. Ascorbic acid can be
found in supplements including multivitamins. Some supplements,
including cold remedies such as Airborne
®
and Emergen-C
®
, may
contain high doses of 1000 mg of ascorbic acid and should not
be taken while using the Sensor. See your health care provider to
understand how long ascorbic acid is active in your body.
