The pharmacy reads the sig and dispenses quantity for 7 days worth only, regardless of the quantity written. If it's 1 tab q 4-6 PRN pain, #60, the pharmacy will give 42 (1 6 times a day x 7 days). When postop pts call to get additional narcotics, I'll call the pharmacy and verify if their insurance will allow it or not. There's some database that prescribers have to check before giving any additional narcotics, and if another provider has given a script then they can't give more, if there's no other script in a certain timeframe they can give more. It's fairly new so I'm still trying to figure out the methodology. I do check with the pharmacy every time, though. One told me it was acceptable because it was a continuation of an acute fill. It's crazy.
