Opioid Conversion Calculator

A cleaner clinical workflow with methadone support, formulation-specific pharmacology and regional product information.

Opioid Conversion Calculator is built for health professionals who need a clear, efficient way to compare opioid doses and review the clinical context behind a conversion.

CALCULATE AND COMPARE

• Calculate total oral morphine equivalent (OME) across multiple opioids and routes.
• Review calculated target doses after applying a chosen Target OME percentage.
• View conservative, rounded-down target and breakthrough dose suggestions.
• Move quickly between the calculation, individual results and supporting information.

REVIEW CLINICAL INFORMATION

• Read practical points alongside formulation-specific pharmacology.
• Switch between supported formulations without leaving the result.
• Follow links to the supporting references.
• View official products and strengths for supported clinical regions, independently from the app language.

TAILOR THE WORKFLOW

• Edit conversion factors and choose which opioids appear with Pro.
• Export and import settings when moving between devices.
• Use the app in English, French, German, Italian, Portuguese (Brazil) or Spanish.

PRO ACCESS

The core calculation remains available without creating an account. Pro adds professional detail and customisation. Available plans, prices and any introductory offer are shown using the information supplied by the App Store before purchase. Purchases and subscriptions can be restored in the app.

CLINICAL USE

Equianalgesic conversions are estimates and do not replace clinical judgement. Consider incomplete cross-tolerance, patient factors, formulation, route, local guidance and monitoring when interpreting a result. Review the references and terms of use before using the calculator in clinical practice.
