Methadone detoxification is a process which must be overseen by addiction professionals within a drug rehab program who realize how difficult and challenging methadone detox can be. Methadone detoxification is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals often 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 must only be done under strict supervision at a drug rehabilitation facility which has practical experience in dealing with this type of detoxification, and where the person can receive further rehabilitation services to address all addiction issues.
