Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab facility who understand how difficult and challenging methadone detoxification can be. Methadone detoxification is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and users frequently revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification must only be done under strict supervision at a drug rehab program which has experience in dealing with this type of detoxification, and where the individual can receive additional recovery services to deal with all addiction issues.
