Cautions

• High blood potassium (hyperkalemia), liver dysfunction, metabolic or respiratory acidosis, renal impairment, hypersensitivity to spironolactone.
• The risk of hyperkalemia is higher in patients with impaired renal function, proteinuria, diabetes and those concomitantly treated with angiotensin-converting-enzyme inhibitors (ACEs), angiotensin receptor blockers (ARBs), nonsteroidal anti-inflammatory drugs (NSAIDs) and moderate CYP3A inhibitors.
• Patients taking moderate CYP3A inhibitors that cannot be avoided should have their dose of eplerenone reduced.
