I've been prescribed Norco 10/325 for the last five years, and I've build a tolerance to it. I've always taken it as prescribed, responsibly. But my question is: Is Norco 10/325 equal in strength to Percocet 7.5/325? I have an appt., coming up with my pain management doctor, because if it is equal in strength, it will be the same thing as the norco. Please help me discern between the two, as the norco does not take away the pain like it use to, it takes just a little away, but still left with pain.
