Methadone detoxification is a process which should be supervised by drug addiction professionals within a drug rehabilitation program who recognize how challenging and difficult 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 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 should only be done under strict supervision at a drug rehab facility which has experience in dealing with this type of detox, and where the person can receive further treatment services to address all addiction issues.
