Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehab facility who recognize how difficult and challenging methadone detoxification can be. Methadone detoxification is known to be far more serious 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 rehab facility which has practical experience in handling this type of detox, and where the individual can receive further rehabilitation services to address all addiction issues.
