Johns Hopkins Opioid Equivalency Table (Download)

Opioids are an important tool in the management of acute and chronic (cancer and non-cancer) pain. Pain and palliative care practitioners are frequently called upon to switch a patient from one opioid regimen to a different regimen either to gain better pain control, to minimize opioid-related adverse effects, to overcome opioid tolerance, or due to a change in patient status. To this end, equianalgesic tables like the Johns Hopkins have been published to guide practitioners in making these calculations. Download Here
