Any opiate can cause anxiety. Sometimes the underlying reason you are on the opiate also causes anxiety. If you have been taking it awhile and your tolerance of it has risen and you have to take more, it doesn't sedate you anyomore, it gives you energy and that is a nervous type of energy, therefore you feel anxious. Hope that helps. If you are a little more specific, I might be able to help you a little further. Hope you feel better.
