Understanding Your Results
Opioid conversions are based on morphine milligram equivalent (MME) factors. Because cross-tolerance is incomplete, a dose reduction of 25–50% is recommended when switching opioids to avoid overdose.
| Drug | MME Factor |
|---|---|
| Morphine | 1 |
| Oxycodone | 1.5 |
| Hydrocodone | 1 |
| Hydromorphone (oral) | 4 |
| Oxymorphone (oral) | 3 |
| Codeine | 0.15 |
| Tramadol | 0.2 |
| Fentanyl patch (mcg/hr) | 2.4 |
| Buprenorphine (mcg/hr TD) | 30 |
| Methadone | Variable |
