Methadone detoxification is a course of action which must be supervised by addiction professionals within a drug rehab program who understand how challenging and difficult 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 typically revert back to methadone to relieve 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 practical experience in dealing with this type of detox, and where the individual can receive further treatment services to address all addiction issues.
