At the pharmacy filling prescriptions for Hubby, they come printed with an array of security features. The paper resists erasures and reproductions with two kinds of thermographic ink. They have codes on them. The one I am looking at has test areas. It was also not filled because the medical professional who wrote it forgot to program the number of pills so it defaulted to zero. I can't think she meant us to go back for a corrected one. My prescription gets called in when I need it, but the system Hubby is on is not set up for that.
