Methadone detoxification is a course of action which must be overseen by substance abuse professionals within a drug rehab program who understand how challenging and difficult methadone detox can be. Methadone detoxification is known to be far more serious in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox must only be done under close supervision at a drug rehab facility which has practical experience in dealing with this type of detoxification, and where the person can receive further rehabilitation services to address all addiction issues.
