Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab facility who recognize how difficult and challenging methadone detox can be. Methadone detoxification is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and individuals frequently revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detoxification must only be done under close supervision at a drug rehabilitation program which has practical experience in dealing with this type of detox, and where the person can receive additional treatment services to deal with all addiction issues.
