Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation center who understand how difficult and challenging methadone detox can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals typically revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification must only be done under close supervision at a drug rehab center which has experience in handling this type of detoxification, and where the person can receive additional recovery services to handle all addiction issues.
