Based on the opioid conversion table, 17 mg of hydrocodone is
equivalent to 10 mg of
morphine. Therefore, 20 mg of Kadian is
equivalent to about 34 mg of hydrocodone. So, if you take 20 mg of Norco every 4 to 5 hours, the norco is stronger than the current dose of Kadian you are taking, as over a 12 hour period, you would have taken 40-60 mg of norco (or 23 - 35mg morphine equivalent).
