Since these meds increase both liver and kidney numbers, I was told by one Dr not to take tylenol, another Dr not to take advil but if I had to take one, take the tylenol to save on the kidney. Then unrelated, a cardiologist prescribed metoprolol for my SVT tachycardia. My daughter who suffers from migraines was already prescribed it for her migraines. My pcp confirmed this last week. It's been 6 months, I've only had one migraine. Ask your Dr about metoprolol.
