Painkiller Calculator

The Morphine Equivalent Calculator calculates the dosage of common opioids as equivalent to 1mg of Morphine, known as their Morphine Milligram Equivalent (MME). If you wanted to keep a patient under 100 MMEs per day, the Morphine Equivalent Calculator could show:

• 5 doses per day of 100mg/5mL solution of Morphine (IV/IM/SD), or

• 4 doses per day of Oxycodone 15mg (PO), or

• 1 patch per 3-day period of Fentanyl 25mcg/hr (TD)

The Morphine Equivalent Calculator also shows you the total MME for any given combination of common opioids and dosages.
