Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug treatment facility 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 users often revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox should only be done under close supervision at a drug rehabilitation center which has experience in handling this type of detoxification, and where the individual can receive additional rehabilitation services to handle all addiction issues.
