Methadone detoxification is a process which should be supervised by drug addiction professionals within a drug rehab facility who realize how challenging and difficult 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 typically revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detoxification should only be done under strict supervision at a drug rehabilitation facility which has experience in dealing with this type of detox, and where the person can receive additional recovery services to address all addiction issues.
