Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehabilitation facility who recognize how difficult and challenging methadone detoxification can be. Methadone detoxification is known to be far more serious in terms of symptoms and duration than even heroin detox, and users 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 detox should 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 recovery services to handle all addiction issues.
