Equianalgesic dose ratios are only approximations and do not account for genetic factors, incomplete cross-tolerance, and pharmacokinetics.

This opioid dose calculator was developed by the Washington State Agency Medical Directors' Group to be used in conjunction with the Interagency Guideline on Opioid Dosing for Chronic Non-cancer Pain. For more info, please refer to the guideline at: AMDG - Opioid Dosing
