Morphine Milligram Equivalents (MME)

Morphine Milligram Equivalents (MME / Opioid Conversion)

Converts a single opioid regimen to total daily morphine milligram equivalents (MME/day) with CDC 2022 oral conversion factors, to gauge opioid risk against the 50 and 90 MME/day guideposts; methadone potency is non-linear — convert only with specialist guidance.
