7.2 Safety Statements
Contraindication
Don’t:
Take medications containing acetaminophen while wearing the
sensor.
Why: Taking medications with acetaminophen (such as Tylenol or
Excedrin Extra Strength) while wearing the sensor may falsely raise your
sensor glucose readings. The level of sensor inaccuracy:
1. Depends on amount of acetaminophen active in your body.
2. May be different for each person.
Consequences: Without correct readings you might miss a severe low or
high glucose event.
Warning
Don’t:
Use the system sensor glucose readings for treatment decisions.
Do: When making treatment decisions, such as the amount of insulin you
need, only use your BG value from your BG meter..
Why: Since they measure your glucose from different body fluids, sensor
glucose readings can be different from your meter’s BG values.
Consequences: If sensor glucose readings are used in determining
treatments, it could result in you missing a severe low or high glucose
event.
