Methadone tapering is the slowest of any opioid due to its long half-life and complex pharmacology. Rushing a methadone taper causes unnecessary suffering and high relapse rates.

When to consider tapering

Stable recovery for at least 2 years on maintenance. Strong support system. Stable life circumstances. No active co-occurring conditions. This should be your decision, supported by your clinical team.

How tapering works

Reduce by 5-10% every 1-2 weeks above 40mg. Slow to 2-5% reductions below 40mg. Below 20mg, reductions of 1-2mg every 2-4 weeks. The entire process may take 6-24 months. Pause or slow the taper if withdrawal symptoms become significant.

Why methadone tapers are so slow

Methadone's long half-life means dose reductions take days to fully manifest. The body needs time to adjust at each level. Rushing causes severe withdrawal and high relapse rates. Slow and steady is the only safe approach.

Post-taper support

Increase meeting attendance and therapy frequency. Consider naltrexone after complete opioid clearance. Have a relapse plan. Monitor closely for the first 6 months off methadone.

Frequently asked questions

How long does it take to taper off methadone?
6-24 months for a comfortable taper. Shorter tapers have much higher relapse rates.
Is methadone harder to quit than heroin?
Methadone withdrawal is more prolonged due to its long half-life, but gradual tapering makes it manageable.
Can I switch from methadone to Suboxone?
Yes, but requires careful management. The transition involves a period of dose reduction, waiting, and Suboxone induction to avoid precipitated withdrawal.
