Methodology · worked example, guidelines & full notes
CDC 2022 states its dosage guidance should not be applied as a rigid threshold.
When to use
Enter each opioid's total daily oral dose; the tool sums the morphine-equivalent total using the CDC 2022 factors.
How it works
Daily MME = Σ (drug daily dose × conversion factor). Factors: morphine 1, oxycodone 1.5, hydrocodone 1, hydromorphone 5, oxymorphone 3, codeine 0.15, tramadol 0.2, tapentadol 0.4.
Key points
- CDC 2022 states its dosage guidance should not be applied as a rigid threshold.
- MME is a risk-assessment metric, not an opioid-rotation tool; CDC states the factors are not for converting between opioids.
- Methadone (nonlinear), buprenorphine (partial agonist), and transdermal fentanyl are excluded and require dedicated conversion methods.
