Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehabilitation center who understand 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 ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox should only be done under strict supervision at a drug rehab program which has practical experience in dealing with this type of detoxification, and where the individual can receive further treatment services to deal with all addiction issues.
