Methadone detoxification is a course of action which must be supervised by drug addiction professionals within a drug rehabilitation facility who understand how difficult and challenging methadone detox can be. Methadone detoxification is known to be far more serious in terms of symptoms and duration than even heroin detox, and individuals typically revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification 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 recovery services to deal with all addiction issues.
