Methadone detoxification is a process which must be supervised by drug addiction professionals within a drug rehab facility who realize how difficult and challenging methadone detox can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals typically revert back to methadone to relieve 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 rehabilitation facility which has experience in handling this type of detox, and where the individual can receive additional rehabilitation services to handle all addiction issues.
