I would dispense with a note that the medication expires after 14 days, and if the patient needed it past that day, that you will have to contact the doctor for a refill. (it's not uncommon for surgeons to prescribe continuous antibiotics until the surgery date, so in these situations, if the date hadn't been finalized, the physician may have left the script open-ended for that reason. If you learn from the patient that is the deal and they need 16 days worth of antibiotics, then I would make the quantity 2 bottles, and either dispense 1 and have them come back for the refill, or if co-pay is an issue, dispense both bottles, but send the water to be added separately with the 2nd bottle.)
