Is There A Difference In Different Generic Pills For The

Is there a difference in different generic pills for the same pill, ( oxycodone/acetamin 7.5 325mg TB) because Ive only been on them thru a Dr. for almost 2 mos. but the last refill at a different pharmacy because it was Thanksgiving day, don't seem to work as well as my first script from my main pharmacy. I'm sure you know I'm taking the generic for Percocet. Bothe pills looked totally different and I do know that not all generics have the same fillers and are not tested as well. Is any one generic company better than another? The ones I have now are by Actavis Id also like to know if I'm better off going back to Hydrocodone acet APAP 10/325(?)for Norco. I had a slip/fall and broke bone in leg and 3 bones in lower arm. The nerves that numbed my leg will be treated this weekend carterizing them,Radio something .Thanks, Trish I have no money, I didn't know it cost from the beginning.I just thought you wanted to halp people. Please nevermind
