Opioid Conversion Giude

Medication conversions are not an exact science. The usual method of converting one opioid to another is to:

  1. Convert current opioid to oral morphine equivalents, i.e., the total daily dose of oral morphine.
  2. Then change to the other opioid using the conversion guide below.

If you have any concerns please phone for advice.
