I used to be on oxycodone 10/325 8 times per day. I have a new Dr. and he switched me to 15mg IMM rel tabs oxycodone twice a day. I just started yesterday by taking half at a time. I didn't really notice any relief. Which med is more potent? The 15 mg has no acetaminophen in and the others have 325 mgs of acetaminophen. I'm confused!
