Methadone detoxification is a course of action which should be supervised by substance abuse professionals within a drug rehab center who understand how difficult and challenging methadone detoxification can be. Methadone detoxification is regarded to be far more severe 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 detox should only be done under close supervision at a drug rehab program which has experience in dealing with this type of detox, and where the person can receive further treatment services to handle all addiction issues.
