I take xarelto 15 mg a day. i also take two tylynol every morning for low back pain. is this too much tylynol to be taking every day? i am in good health?

Presuming your Tylenol tablets are 500mg or less, that is not too high a dose to be taking daily. But of course, it is always a good idea to discuss every medication that you are taking with your primary care doctor, no matter how insignificant they seem.

As long as you keep you intake of Tylenol to less than 3-4 gm/day, and avoid alcohol, you should be okay.
