Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehab facility who understand how difficult and challenging methadone detoxification can be. Methadone detoxification is known to be far more serious in terms of symptoms and duration than even heroin detox, and users often 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 must only be done under close supervision at a drug treatment program which has experience in dealing with this type of detox, and where the individual can receive further recovery services to deal with all addiction issues.
