When I was an intern I had to admit a patient with FBSS who was on most available opioids. I don't remember the doses anymore but the total was around 10000 MED. It was difficult to determine exactly because he was chugging Roxanol from the bottle without measuring it. Methadone, MS Contin, Oxycontin, Dilaudid, Fentanyl patches, Roxycodone, MSIR, all at ridiculous doses. He also had a PICC line for IV Demerol, which he self-administered 8 times daily. On several muscle relaxants and anticonvulsants and at least 3 different NSAIDs.
He was on a total of 57 medications, which caused the EMR to crash on medication reconciliation.
His PCP yelled at me when I questioned this regimen. The wise pain consultant recommended "discharge ASAP." He was OK with this plan because we took away his jug of liquid morphine.
