If you have experience switching from vicodin to this patch I would love to hear what dose vicodin you were on when you switched. The information sheet for Duragesic doesn't make sense to me . . .the table states that 150 mg hydrocodone per day is the minimum you should be tolerating to make the switch. That seems so high, especially as a minimum. Vicodin 5/500 at 2 tablets four times a day would only equal 40 mg. hydrocodone per day. . . Thanks for your input. I have the opposite problem as most of you -- my doctor is prescription happy and I have to be sure she's not going overboard before I take her recommendations.
