I have had a 25mcg Fentanyl patch on since 10.30am. It is 11.22 pm now. If I was going to have any reactions from it would they have happened by now? My doctor just put me on these and how long do they take to kick in?
Have you been on Fentanyl prior? Usually they will start you out on 12.5 mcg than work you up from there. 25 mcg is not that strong of a dose, but it takes at least 24 hours to get into your system. However, fentanyl is a very powerful and dangerous drug. Advice is to follow the instructions and give it time to work. Don't experiment.
