Methadone detoxification is a process which must be supervised by addiction professionals within a drug rehabilitation 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 users often revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification must only be done under strict supervision at a drug rehab program which has practical experience in dealing with this type of detox, and where the individual can receive further treatment services to address all addiction issues.
