Methadone detoxification is a process which must be supervised by addiction professionals within a drug rehab facility who recognize how difficult and challenging methadone detox can be. Methadone detoxification is regarded to be far more serious 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 relieve symptoms. This is why methadone detox should only be done under strict supervision at a drug rehab facility which has experience in handling this type of detoxification, and where the individual can receive further rehabilitation services to address all addiction issues.
