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