- you have high potassium levels in the blood, aluminum toxicity, heart failure or injury, or severe kidney problems
- you are taking an aldosterone blocker (eg, eplerenone), an aluminum salt (eg, aluminum hydroxide), a potassium-sparing diuretic (eg, triamterene), or sucralfate
Contact your doctor or health care provider right away if any of these apply to you.
