Methadone detoxification is a process which should be supervised by drug addiction professionals within a drug rehab center who understand how difficult and challenging methadone detox 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 relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification must only be done under close supervision at a drug treatment facility which has practical experience in handling this type of detoxification, and where the person can receive further treatment services to address all addiction issues.
