I am not sure why this is different as you can do this on the old scripts, but there is a big point that the total number of days should be the prescribed amount plus refills so that:
Zyrtec 1 po daily
Dispense 30 pills times two refills
Days supply 90.
That is bizarre especially since Medicaid (at least MaineCare here in Maine) requires a 90 day supply. Therefore it would be written:
Zyrtec 1 po daily
Dispense 90 times three refills (covering a year(
Days supply 360
