The use of potassium-sparing diuretics is contraindicated in patients with anuria, acute or progressive renal insufficiency, or diabetic nephropathy. Potassium-sparing diuretics can cause hyperkalemia, which may result in life-threatening cardiac arrhythmias.

Examples of medications that may lead to elevated potassium levels include: 1  nonsteroidal antiinflammatory drugs, 2  ACE inhibitors,
