Morphine Milligram Equivalents (MME) Calculator
There is no completely safe opioid dose, and this calculator does not substitute for clinical judgment. Use caution when prescribing opioids at any dosage, and prescribe the lowest effective dose.
Conversions are based on the CDC Guideline for Prescribing Opioids for Chronic Pain — United States, 2016.
Note: This is for converting oral opioids only, and should not be used for IV to oral conversions.
For combination drugs (e.g. Percocet = acetaminophen + oxyCODONE), enter only the dose of the opioid component (e.g. if 5 mg/325 mg, enter "5"). Do not use in pediatric patients, due to unpredictable rates of absorption and risk of overdose.
As a partial opioid agonist, buprenorphine is not expected to be associated with overdose risk in the same dose-dependent manner as doses for full agonist opioids and is therefore omitted from the calculator.
