Don't worry about it! I've been a chronic pain patient for 15 years going to different doctors and such for second opions, but mainly I always go to the same pharmacy. and IF theres any question about the script they call thr Dr. rite then and there. its not a triplicate scropt so the Dr. will never see it again after so many weeks or so the paper script is destroyed and thats the end of it,
I've had legit scripts questions and they called rite there, so if they filled it DON'T worry, next time just ask the Dr. to make it the ES, God Bless, Tim

Ps I've known people to add a 1 in front of the 15 and got away with it.
