While effort has been made to ensure that calculations are accurate and that conversion factors are in accordance with current accepted medical practices, use of this application is entirely at your own risk. This application should only be used by trained medical professionals and all results should be double checked by hand. Use of the app requires acceptance of the terms of use that are included with the application.

Please send support requests and feedback using the link in the About tab of the app, though as a free academic tool we only have limited resources to address new feature requests.

Opioid equipotency data is taken from CAPC conversion values except where noted (see the reference tab in the app.) CAPC values are as published in the Center to Advance Palliative Care Prescribing Opioids: A Reference Guide curriculum, which are adapted from McPherson ML. Demystifying Opioid Conversion Calculations: A Guide for Effective Dosing, 2nd ed. American Society of Health-System Pharmacists, Bethesda, Maryland, 2018. EPEC values are as published in EPEC-O Participants Handbook, 2005.

What’s New

Version 3.0.2

Use traditional conversion (1:2) for fentanyl based on clinical experience and increased safety (regardless of incomplete cross tolerance) when transitioning to oral opioids from transdermal fentanyl. 

Also, includes all updates in the 3.0 version:
Changed opioid equipotency calculations to use CAPC conversion tables (which are adapted from McPherson's Demystifying Opioid Conversion Calculations...).
Simplify methadone conversion tables and remove outdated "Rule of 15" usage. Added new guidance comments for methadone initiation.
Updated reference tab documentation.

Pretty good opioid calculator

When I upgraded my iPhone to iOS 8, I lost the ability to use my original opioid calculator app, the opioid. This is a fairly suitable replacement, and it works well with good stability on my iPhone 5S running iOS 8. The only suggestion I would have is that it is cumbersome to enter in numerical quantities for milligrams received using "rollers" instead of a keypad.

Great app!!

I use it everyday working in pain management! The only improvements you could make is add Nucynta and a two a day dose for Fentanyl Patch!!

Needs IV option for fentanyl

Otherwise excellent app! Recommended throughout anesthesia and palliative departments
