Transfer of Prescription Information | Arizona State Board of Pharmacy

They changed the practice rules quite a bit ago, and it requires the script verified. My aunt was cited for calling in the prescription rather than getting a number set up right as they were changing the policy and started pressuring the political side for change in the AAC. A bunch of pharmacists from her generation still won't transfer new scripts, because they've been hit with complaints anyway, so the local practice is usually to refuse the transfer and ask the pharmacist to call the prescriber's agent.
I ran into this for the first time trying to get a script from a CVS. I guess CVS doesn't assign a number until it's been verified at least once which was weird so I had the pharmacist push it through and then just reverse it and it had a number and she could transfer it. It was a pretty weird situation that I had me at a loss at first.
