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 detox can be. Methadone detox is known to be far more serious in terms of symptoms and duration than even heroin detox, and individuals frequently revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detox should only be done under close supervision at a drug rehabilitation program which has practical experience in handling this type of detox, and where the individual can receive further treatment services to deal with all addiction issues.
