Comments: -ISMP suggests when prescribing this drug for pain, consider all patients as opioid naive; consider limiting the starting dose to oral doses not exceeding 20 mg per day (10 mg for the elderly or infirmed) and limit dose adjustments to once a week to allow steady state levels to develop. -Prescribe oral liquid doses in mg to avoid confusion. -Dose conversion should be done carefully and with close monitoring due to large patient variability in regards to opioid analgesic response. -This drug is not indicated as an as-needed analgesic. -Upon cessation of therapy, gradually taper dose in physically dependent patient. The maintenance dose is typically between 60-120 mg. However, metabolism rates vary greatly between individuals, up to a factor of 100,[48][49] ranging from as few as 4 hours to as many as 130 hours,[50] or even 190 hours.[51] This variability is apparently due to genetic variability in the production of the associated cytochrome enzymes CYP3A4, CYP2B6 and CYP2D6. Closely monitor patients for changes in cardiac rhythm during initiation and titration.
Additional studies demonstrated that methadone treatment of male rats for 21 to 32 days prior to mating with methadone-naïve females did not produce any adverse effects, suggesting that prolonged methadone treatment of the male rat resulted in tolerance to the developmental toxicities noted in the progeny.

The medication is administered in liquid or tablet form on a daily basis.
Forced diuresis, peritoneal dialysis, hemodialysis, or charcoal hemoperfusion have not been established as beneficial for increasing the elimination of methadone or its metabolites.
