Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehab center who recognize how difficult and challenging methadone detox can be. Methadone detox 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 ease 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 rehabilitation center which has practical experience in handling this type of detox, and where the individual can receive further treatment services to deal with all addiction issues.
