I am not sure about your pathology but 25 mcg of Fentanyl is the minimum dose. It can go as high as 500 mcg, but typically not for OC patients. You may be better of with Morphine Sulphate for breakthrough pain as it is the fastest acting. Motrin is a medium strength pain killer. People here have had their Fentanyl dose rates, typically worked up (it can only be safely increased in 25 mcg increments) from 75 to 150 mcg.

I think your pain management team is short changing you. It is a basic patient right to have adequate pain management 3-4 max pain range, in other words, bearable. Use the number system to describe your pain - 10 being unbearable.
