Why MME matters
MME turns different opioids into one comparable potency measure so you can assess total opioid exposure. Learn which inputs change the outcome next.
Step 1: Enter meds and doses
List each opioid, its strength, daily amount and formulation, and confirm units to avoid errors. Next, see how those values become morphine equivalents.
Step 2: Apply conversion factors
The calculator multiplies each drug amount by its opioid-specific factor to estimate an equivalent morphine dose; watch for special cases and limits. Then find out how to combine them.
Step 3: Total and interpret
Add each medication’s estimated MME to get a total figure. Treat it as an approximation and check labels and ranges before clinical use—read about accuracy next.
