Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehabilitation program who recognize how difficult and challenging methadone detox can be. Methadone detoxification is known to be far more severe in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to alleviate 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 center which has experience in handling this type of detoxification, and where the individual can receive additional rehabilitation services to handle all addiction issues.
