eviQ v3 Opioid Conversion: Official Tool and Safety Guide
Use the official eviQ Opioid Conversion Calculator 3201 v3 for opioid-conversion calculations and its current warnings. OncoToolkit does not reproduce the conversion algorithm or provide an external-result recorder.
Why the official tool matters
Opioid conversion is not a simple prescribing instruction. eviQ states that its conversions are guides, must be confirmed, and require clinical judgment. Patient factors, the pain syndrome, organ function, incomplete cross-tolerance, available formulations, and close reassessment all matter.
The official calculator derives oral morphine equivalent daily dose before converting to a target opioid. It also carries source-specific exclusions and warnings that should remain attached to the calculation.
Important safety boundaries
- Suspected overdose or respiratory depression requires urgent clinical assessment.
- Uncontrolled or rapidly escalating pain should not be managed by a routine calculator result alone.
- Methadone and complex fentanyl conversions require experienced specialist input.
- Renal or hepatic impairment can materially change opioid selection and dosing.
- A calculated dose does not replace review of local policy, formulary, interactions, and patient response.
