NICU IV fentaNYL to PO Morphine Calculator


Note: This provides a rough estimate for converting IV FentaNYL to PO morphine. There is significant individual response to various opioids as well as unpredictable or incomplete tolerance between opioids; clinical judgement must always be used when converting opioids.
