fda label

valsartan + potassium

Valsartan is an angiotensin II receptor blocker that suppresses aldosterone, which slows the kidneys' excretion of potassium. The FDA-approved Diovan label warns that potassium supplements and potassium-containing salt substitutes may raise serum potassium to clinically significant levels, particularly in people with reduced kidney function, diabetes, or heart failure.
