Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehabilitation facility who realize how challenging and difficult methadone detoxification can be. Methadone detoxification is regarded 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 alleviate symptoms. This is why methadone detox should only be done under strict supervision at a drug rehabilitation program which has practical experience in dealing with this type of detoxification, and where the person can receive additional rehabilitation services to handle all addiction issues.
