Frequently Asked Questions
Why does methadones conversion factor change?
Methadones potency relative to morphine increases at higher daily doses, so its conversion factor rises from 4 at 20 mg/day or less up to 12 at over 60 mg/day.
What MME level is considered high-risk?
The CDC identifies 50 MME/day as an increased-risk threshold and 90 MME/day as a level warranting particular caution, though every patient and situation differs.
