I actually have more trouble with
Ibuprofen than I do with
Tylenol. I had asked my Doctor about it
and he told me that Ibuprofen was just as harmful in large doses.
With you having an occasional drink and you taking the prescribed medication, I would not worry about your intake of Tylenol or Ibuprofen. It can be a concern if you take these drugs on a regular basis or long term. Most Doctor will not prescribe the medication with those additives.
