Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehab program who understand 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 individuals frequently revert back to methadone to ease 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 treatment program which has practical experience in dealing with this type of detoxification, and where the person can receive additional treatment services to handle all addiction issues.
