I have been using fentanyl subliminal (?) Tablet 400mcg for approximately 1 year when I was switched to the Subsys fentanyl 1600 mcg spray. I was on this spray for 1 year. I was abruptly taken off of this medicine (cold turkey). My only saving grace was some 200 mg Nucynta tablets that I had used for break through pain ( Friday through Tuesday) I used these tablets until the doctor could see me last Tuesday @ 2:45PM. I have been given 60 MG morphine sulfate and 8 MG hydromorphone. I am starting to hurt through my chest and legs and hands. I am starting to have some sweats. My question is: are these pains part of cold turkey from the Subsys or new symptoms of the new meds I have been given? Lastly, how long does the fentanyl last in my system?
