Previous poster is being a bit over dramatic, but it's on you for the pharmacy to be compliant and above board. If the store gets docked for something on a state board inspection, it's on you. Just be diligent, keep close accounts on your controls, make sure your techs follow correct procedure on counseling, etc and you will be ok.
The most common things to look out for are board inspections (are your control scripts properly marked, valid and on hand for an inspector to see, employee and store licensing up to date, etc). Misfills and/or lack of following proper counseling procedures are the most likely things that can trip you up.
Look up state board fines in your state to get an idea of what commonly gets a pic in trouble. Most common in my state are techs not getting the pharmacist to offer counseling on a new rx. Drill it in your techs and other pharmacists to follow your state's regulations on that.
I had a bad misfill at my store when I was off on vacation, and it was largely due to the floater RPh not offering counseling on a new med. I had emails showing I had reminded this particular RPh and others to follow protocol, as well as a write up on a clerk for not informing the RPh if a script was new.
The board cleared the store and myself and issued a warning to the floater RPh. Don't be a jerk about it, but you have to protect yourself and have things in writing that show you're doing your job to properly dispense meds.
Being a PIC can be rewarding and offer a layer of job security, but don't take it lightly. You aren't there to simply fill meds like a staff RPh would.
