Fentanyl

Good night ladies and Gents!
I have a question. I have a pt that needs to place two Fentanyl patches on at the same time the dose of one patch is 12.5mg the lowest dose. So Dr is ok with pt using 2 patches. My question is can i put both patches on the same side? or do i need to put one on 1 side and the other on the other side?
Because you have to rotate the site (Q3 days in my facility) I place them on the same extremity/ side and so that is it easier to rotate

Yup if I we have to put two patches on in our facility, we stick them together on one arm or together on the upper back. Easier to find them later if they are together.

I would put both on the same side. Easier to remember where they are to rotate them. So if on Monday you apply both to the right upper back, then on day 3 you can put them somewhere else like left upper back.
