First step: Under 'Converting from' select the first opiate you want converted. Under 'Converting to' select the opiate you want to convert to.

Second step: (optional) You can select additional opiates to convert in addition to what was selected under 'Converting from' on the first screen. This option is perfect for patients on multiple opiates and you would like to convert the patient to a single opiate.

Third step: You may modify the equianalgesic conversion factors if necessary.

Methadone dosing options:  (1) Hybrid method (2) Morley and Makin method


Methadone conversion algorithm - User-adjusted Hybrid method:  With this method, you will be able to modify the conversion ratios used to convert from other opiates to methadone. Several dosage ranges (e.g. 0-99 mg, 100-299mg, ...) and the corresponding ratio used to convert from morphine equivalents (mg)  to methadone are listed. If you disagree with the default settings, simply select a different ratio using the drop-down menu. Simply select the ratio that you feel is the most appropriate.

Morley and Makin Method1:  This method recommends giving methadone that is equal to one-tenth of the calculated morphine equivalents (mg), every 3 hours as needed (maximum of 8 doses/day). On the sixth day, the average total daily dose is calculated from the number of doses needed on days 4 and 5.  This information is used to formulate the maintenance dose.  After this time, a short-acting opiate may still be required for breakthrough pain. Five or Six days of titration are usually adequate for most patients.  IMPORTANT: The initial titration dosage is limited to 30mg when the calculated morphine equivalents is greater than 300mg.

Dose ratios ranged from 2.5:1 to 14.3:1 (median, 7.75:1)"
