(Equivalent to morphine 5 mg IV intermittent or IM/subcutaneous)
*Duration of action is for IV intermittent, IM/SUBCUT, and PO routes; IV direct administration has shorter duration of action
**For short-term pain management if normal renal, hepatic, and CNS function and alternative opioids are contraindicated.
***Note that this table is uni-directional for morphine to fentanyl transdermal patch conversion only. Conversion does NOT apply when switching from fentanyl transdermal patch to morphine (use extreme caution).
- two TYLENOL # 3 tablets (acetaminophen-codeine 300-30 mg per tablet) is approx. equivalent to morphine 10 mg PO
- two 292 tablets (ASA-codeine 375-30 mg per tablet) is approximately equivalent to morphine 10mg PO
- In round the clock administration of opioids, the IVintermittent/IM/subcutaneous routes are essentially equianalgesic
- The oral, rectal and sublingual routes are equianalgesic (when rectal/sublingual dosage forms are available)
- Dosing frequency is usually based on the duration of action of the analgesic used; however, certain individuals may obtain control with longer dosing intervals, and some patients may need more frequent analgesic administration.
- Equianalgesic doses and intervals are based on available published data and clinical experience.
