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