Step 1, Calculate current total dose oral Morphine over 24 hours. 2 x 90 mg = 180 mg. Step 2, Convert to equivalent dose of Parenteral morphine by dividing total 24 hour oral dose by 3 Morphine injections for break through pain can be safely given every 15 minutes (peak effect of IV Morphine is about 5 minutes).
180 mg divided by 3 = 60 mg Step 3 Calculate hourly dose of Parenteral morphine by dividing the total 24 hour dose by 24.

CONTEXT: The lack of knowledge of the accurate conversion ratio (CR) between intravenous (IV) and oral hydromorphone and opioid rotation ratio (ORR) between IV hydromorphone and oral morphine equivalent daily dose (MEDD) may lead to poorly controlled pain or overdosing in cancer inpatients.

The lack of knowledge of the accurate conversion ratio (CR) between intravenous (IV) and oral hydromorphone and opioid rotation ratio (ORR) between IV hydromorphone and oral morphine equivalent daily dose (MEDD) may lead to poorly controlled pain or overdosing in cancer inpatients.
Patient characteristics, symptoms, and opioid doses were determined in patients successfully discharged on oral opioids without readmission within one week.
Note: This calculator is to be used as a guideline when converting opioid agonists in patients receiving short-term therapy. When calculating a 24 hour continuous IV infusion requirements based on requirements of small boluses, the IM and IV total dose are assumed to be equivalent since Morphine (oral) - 30 mg.
