I've used fentanyl patches in the past for chronic pain, but was not opioid-tolerant enough for them to be appropriate until now, several years later. Regarding the question, based both on experience and info I've found on the web, it takes fentanyl patches about 12 hours to begin working, and about 24-28 hours for peak pain relief to start. And, as I'm sure you know, they should last for (and one should only use one every) 2 - 3 days.

No, but Norco is such a weak opiate compared to Fentanyl patches that you'd likely never feel the effects if you did take any.
At least 2 days.
