It might be that he increased your fentanyl too much at once. The jump from 100 mcg to 200 mcg, without slowly increasing the dose is not ordinarily done. I have been on as much as 300 mcg of fentanyl at one time and when we went up that much, we went in 25 and 50 mcg increases to get there.
I just wanted to say ditto to that. 100mcg is a huge
jump and would probably give any normal person a headache, so there's no telling what it would do to you if you have a pr
opensity toward headaches/migraines to begin with! My doctor is very conservative when he moves my fentanyl doses around and only moves me 12.5mcg at a time, which really irks the pharmacist for some reason that I don't entirely understand.
