That's what mine said too. I have taken Benadryl twice since surgery but luckily haven't needed anything else.

I will be proactive and see if I can get a list of anything besides Tylenol that is acceptable if needed. My 2 years of coverage (donor related) at Mayo is over and my regular Dr. prefers I consult a Nephrologist but that seems like an exaggerated response, especially since I am in good health, with no kidney problems.
