My doc told me:

to be careful when taking 2 x 500 mg Tylenol and Voltaren.....I was told
NOT to do this daily (I don't)  because it can be hard on the kidneys.

I forgot my Voltaren today....but took  (2)  500 mg
tabs from my purse  at Walmart

Will try to do  without Voltaten tonight........bottom
line.........don't mix the two on a daily basis or without asking your
doctor's advice.
