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 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 relieve symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehab program which has experience in handling this type of detox, and where the individual can receive additional treatment services to handle all addiction issues.
