Bert,
I keep the tamper proof paper in my office or in the exam rooms out of sight, but I suppose if a patient wanted tamper proof paper they could order easier on line than lifting it from my office or exam rooms. Plus they wouldn't get much. I only keep a few sheets cut in half in each exam room at any one time. The big stockpile is in my office.
I am not aware of patients around here stealing tamper proof paper.
How do you keep it secure?
I do not use prescription pads much anymore, but never keep prescription pads in the exam room.
I only keep regular white paper in the printer at all times and feed the tamper proof paper one at a time into the printer only when printing a scheduled drug.
Only one printer per exam room, one in my office, and one for my nurse--a total of 4 printers.
