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