Opioid MME Calculator (CDC 2022)
Build up a row per prescribed opioid - drug, mg per dose, doses per day - and Sophie Well totals the daily morphine milligram equivalent using the CDC 2022 conversion factors (MMWR Recomm Rep. 2022;71(3):1-95).

Example
- Opioid
- morphine
- mg per dose
- 30
- Doses per day
- 6
Result: Morphine 30 mg x 6 doses/day = 180 total MME (CDC thresholds 50 and 90).
The tool opens with these values already filled in. Replace them with your own.
What you enter
- Opioid
- mg per dose
- Doses per day
What this is
Per-drug breakdown is shown so the math is auditable; the CDC 50 / 90 MME thresholds are flagged when crossed.
When to use it
Use this when reviewing a chronic-pain regimen, a hospital discharge prescription, or a referral for tapering. The 50 / 90 MME thresholds are framing values, not hard cutoffs; the 2022 CDC update explicitly warns against using them as absolute prescribing limits.
