Adverse Reaction:
WARNINGS-
Deaths have been reported during initiation of methadone treatment for Opiod
dependence. In some cases drug interactions with other drugs both lieit and
ilieit have been suspected. However in other cases deaths appear to have
occured because of respiratory or cardiac effects of methadone and too-rapid
titration without appreciation of accumulation of methadone over time.
It is critical to understand the pharmocokinetics of methadone and to excercise
vigilance during initiation and dose titration. Patients must also be strongly
cautioned against self-medication with CNS depressants during initiation of
methadone treatment.
Respiratory depression is chief hazard asociated with methadone administration.
Methadones peak respiratory depressant effects typically occur later and persist
longer than than its peak analgesic effects ,particularly in the early dosing period.
These characteristics can contribute to the case of iatrogenic overdose,particularly
during the treatment initiation and dose titration

Oral administration is preferred . However, if patient is unable to ingest oral
methadone the parentral form may be used.
Initially 15 to 20mg will often supress withdrawal symptoms. Provide additional
methadone if withdrwal symptoms are not supressed or if symptoms reappear.
When patients are physically dependent on high doses. 40mg/day in single or
divided doses is usually adequate an stabilizing dose.
Continue stabilization for 2 to 3 days, then gradually decrease the dose on a daily
basis or at 2 day intervals.
Provide a sufficient amount to keep withdrawal symptoms at a tolerable level.
In hospitalized patients a daily reduction of 20% of total daily dose may be tolerated
Maintenance treatment- Individualize dosage. Initial dosage should control abstinence
symptoms following narcotic withdrawal, but should not cause sedation , respiratory
depression or other effects of acute intoxification.
If patients have been heavy heroin users up to admission day, they may be given
20mg methadone 4 to 8 hours after heroin is stopped or 40mg in a single dose.
If they enter treatment with little or no narcotic tolerance, initial dosage may be
halved. When in doubt use smaller dose. If abstinence symptoms are depressing,
give additional 10mg doses as needed.
Adjust dosage as tolerated and required, upto 120mg/day
