I Have Recently Had Hip Replacement (5 Months) And Will

I have recently had hip replacement (5 months) and will need the other hip done in the near future.
I have been a steady diet of Tylenol because of the hip that is not yet taken care of. I just received a report that my liver enzymes have elevated. If this is due to the Tylenol, what would a good OTC replacement be. I cannot go to my home doctor until after the holidays. Hope you have some suggestions.
Thank you
