Equianalgesic conversions used in this calculator are based on the American Pain Society guidelines and critical review papers regarding equianalgesic dosing. 4, 5, 6, 7 When possible, chronic-dosing studies have been used, including bidirectional and dose-dependent conversions.
The calculator provides conversions from one opioid to another and/or from one route of administration to another, to be used as a guide only. It is not tailored to any specific pain syndrome or for utilisation by specific healthcare professionals.
Morphine Milligram Equivalents (MME) Calculator. Calculates total daily morphine milligram equivalents. IMPORTANT. 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.
