Contraindications[edit]
Spironolactone is considered Pregnancy Category C by the FDA and should not be taken by pregnant women due to the high risk of birth defects and feminization of male fetuses. Likewise, it has been found to be present in the breast milk of lactating mothers and, while the effects of spironolactone or its metabolites have not been extensively studied in breast-feeding infants, it is generally recommended that women also not take the drug while nursing.[14][39]
It should also be used with caution in patients with some neurological disorders, anuria, acute kidney injury, or significant impairment of renal excretory function with risk of hyperkalemia.[39]
