There's a prescriber at a local hospital that discharged all his post surgery patients with norco 10 take 1-2 q 4-6hrs, opioid naive or not. I always called and always got told to eff off when I asked to amend the directions to at least add max 6 tablets daily. I always handed it back and explained why, telling the person if they fill it to please know typical max recommended dose is 6 per day.
Had a wife that got very upset about not filling it for her 80 year old husband who came back a week later to tell me he stopped breathing and had to be treated and resuscitated on her living room floor. Luckily he survived. That prescriber still uses the same old sig, but doesn't argue about amending the max dosage anymore. He got smart with me once, and I mentioned his prior patient almost dying on his living room floor...he doesn't argue with me anymore.
It's easy to get wrapped up in the retail mindset of make the customer happy and avoid prescriber conflict, but at the end of the day, you have to remember your job is also to prevent harm to the patient, customer service be damned.
