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