Of you take 1 or 2 in the evening after a tough day the 7.5/750 should be okay, but if you need it every 4 hours, that's 6 x day.....4500mg of Tylenol is over recommended dosing. If you like your liver at all ( ), I'd ask your doc for a switch to the 7.5/325.

For someone with less pain or new to narcotics, the Tylenol is there to potentiate (make it work better) the hydrocodone. When you've been dealing with chronic pain awhile, the benefit of the Tylenol is negligable and the risk of liver damage is greater.
