Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehabilitation program who understand 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 relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification must only be done under strict supervision at a drug rehabilitation program which has experience in dealing with this type of detoxification, and where the individual can receive additional treatment services to address all addiction issues.
