I'm glad you decided to join in and ask about this problem. I sure can see why you are worried. One thing to take into consideration....it's your body and you are entitled to only take as much medication as you see fit. For some people that's none and for others they take all the doctor will prescribe..and some even more.
From what I have read you can go a lot higher on Duragesic that where you are but don't hold me to that. Even so that's a lot of pain medication. Something else to consider...are you quite tolerant of the medication? Duragesic is only supposed to be used on people who have previously been on narcotic medication, it's not the first drug to try. I hope your doc considered this. There are warnings all over the interned sites with that warning on them.
I would talk to the doctor about your concerns. It sure would concern me also. Plus, if you can make do with less then I would just use less. In my opinion your doctor prescribed the highest dose you can take if you want but I wouldn't think you have to take it all. The only problem is that with patches you can't cut them and I don't think you can keep them on longer than 3 days because the medication will be depleted. Hopefully your doc will work with you on this.
Bottom line...it's your body! Keep in touch...
