Methadone detoxification is a process which should be supervised by addiction professionals within a drug rehab facility who understand how difficult and challenging methadone detoxification can be. Methadone detoxification is known to be far more severe in terms of symptoms and duration than even heroin detox, and users 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 must only be done under strict supervision at a drug rehabilitation facility which has experience in dealing with this type of detoxification, and where the individual can receive additional recovery services to handle all addiction issues.
