Methadone detoxification is a course of action which must be supervised by addiction professionals within a drug rehab program who recognize how challenging and difficult methadone detoxification can be. Methadone detox is known to be far more serious in terms of symptoms and duration than even heroin detox, and users frequently 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 program which has experience in dealing with this type of detox, and where the individual can receive further treatment services to address all addiction issues.
