Today I was prescribed Fentanyl patches, 50mcg. I have a tolerance for opiates. I can usually handle 3.5 tab 10's every 4 hours or 2 perc 10's every 4 hours. I have also used Roxy 30's in the past. For some reason they didn't work as well as the lortab. I would have to take a whole one and then a quarter of another one, just for it to work. I have never used Fent before, and I'm just curious if the dose is too much or not considering I have a tolerance. How long does it take to kick in? Is it the same type of feeling you get from just regular pain pills?
