Methadone detoxification is a process which should be supervised by addiction professionals within a drug rehab program who understand how challenging and difficult methadone detox can be. Methadone detoxification is known to be far more severe in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehab facility which has practical experience in handling this type of detox, and where the person can receive additional recovery services to address all addiction issues.
