Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehabilitation facility who understand how challenging and difficult methadone detoxification can be. Methadone detoxification is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and users often revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detox must only be done under strict supervision at a drug rehabilitation center which has experience in dealing with this type of detoxification, and where the person can receive further rehabilitation services to handle all addiction issues.
