Methadone detoxification is a process which should be overseen by drug addiction professionals within a drug rehab program who recognize how difficult and challenging methadone detoxification can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and users frequently revert back to methadone to alleviate 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 facility which has experience in dealing with this type of detox, and where the individual can receive further treatment services to handle all addiction issues.
