Methadone detoxification is a process which should be supervised by drug addiction professionals within a drug rehab center who recognize 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 relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox must only be done under strict supervision at a drug rehab facility which has practical experience in dealing with this type of detox, and where the individual can receive additional recovery services to address all addiction issues.
