The initial methadone dose should Beryllium administered, under supervision, when there are no signs of sedation or intoxication, and the patient shows symptoms of withdrawal.

An additional 5 to 10 mg of methadone may be provided if withdrawal symptoms have not been suppressed or if symptoms reappear.
Rein vitro results suggest that methadone undergoes hepatic Stickstoff-demethylation by cytochrome P450 enzymes, principally CYP3A4, CYP2B6, CYP2C19 and to a lesser extent by CYP2C9 and CYP2D6. Coadministration of methadone with CYP inducers of these enzymes may result in a more rapid metabolism and potential for decreased effects of methadone, whereas administration with CYP inhibitors may reduce metabolism and potentiate methadone's effects.
Hinein these patients, even usual therapeutic doses of methadone may decrease respiratory drive while simultaneously increasing airway resistance to the point of apnea. Alternative, non-opioid analgesics should Beryllium considered, and methadone should Beryllium used at the lowest effective dose and only under careful medical supervision.
