Black Box Warnings
Spironolactone has been shown to be a tumorigen in chronic toxicity studies in rats; use only for specified indications
Contraindications
Hypersensitivity
Addison disease or other conditions associated with hyperkalemia
Coadministration with eplerenone
Cautions
Gynecomastia reported and usually reversible
Hyponatremia, hypomagnesemia, hypocalcemia, hypochloremic alkalosis, and hyperglycemia may occur
Asymptomatic hyperuricemia can occur and rarely gout may occur; monitor serum electrolytes, uric acid, and blood glucose periodically In cirrhosis, avoid electrolyte and acid/base imbalances that might lead to hepatic encephalopathy
Hyperkalemia may occur; monitor serum potassium within 1 week of initiation or titration of spironolactone and regularly thereafter; if hyperkalemia occurs, reduce dose or discontinue treatment and treat hyperkalemia
Excessive diuresis may cause symptomatic dehydration, hypotension and worsening renal function, particularly in salt-depleted patients or those taking angiotensin converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs)
Drug interactions overview
- Coadministration of PO suspension and lithium reduces the renal clearance of lithium, inducing a high risk of lithium toxicity
- Reported that of coadministration of PO suspension and an NSAID can reduce the diuretic, natriuretic, and antihypertensive effect of loop, potassium-sparing, and thiazide diuretics
- NSAID administration can reduce diuretic, natriuretic, and antihypertensive effect of diuretics; when spironolactone and NSAIDs are used concomitantly, monitor closely to determine if the desired effect of the diuretic is obtained
- Acetylsalicylic acid may reduce the efficacy of spironolactone; coadministration with acetylsalicylic acid may need to be titrated to higher maintenance dose and monitor closely to determine if the desired effect is obtained
- Coadministration of spironolactone with potassium supplementation, salt substitutes containing potassium, a diet rich in potassium, or drugs that can increase potassium (eg, ACE inhibitors, ARBs, NSAIDs, heparin and low molecular weight heparin) may lead to severe hyperkalemia
- Risk of worsening of renal function can also occur with concomitant use of nephrotoxic drugs (eg, aminoglycosides, cisplatin, NSAIDs); monitor volume status and renal function periodically
- Spironolactone and its metabolites interfere with radioimmunoassays for digoxin and increase the apparent exposure to digoxin; use an assay that does not interact with spironolactone
- Hyperkalemic metabolic acidosis reported in patients given spironolactone concurrently with cholestyramine
- Spironolactone and its metabolites increase the apparent exposure to digoxin; in patients taking concomitant digoxin, measure serum digoxin concentrations before initiating spironolactone using an assay that does not interact with spironolactone; reduce digoxin concentrations by decreasing dose by approximately 15-30% or by modifying dosing frequency and continue monitoring
- Spironolactone is an irreversible inhibitor for CYP2C8 and CYP3A4/5 in vitro; may increase exposure of other coadministered drugs that are metabolized by CYP2C8 and CYP3A4/5; dosage adjustments of drugs metabolized by CYP2C8 (eg, repaglinide) and CYP3A4/5 (eg, midazolam, sirolimus, and tacrolimus) may be necessary if they are given concurrently with spironolactone
Pregnancy & Lactation
Pregnancy
Based on mechanism of action and findings in animal studies, spironolactone may affect sex differentiation of the male during embryogenesis; rat embryofetal studies report feminization of male fetuses and endocrine dysfunction in females exposed to spironolactone in utero
Limited available data did not demonstrate an association of major malformations or other adverse pregnancy outcomes with spironolactone; risks may occur to the mother and fetus associated with heart failure, cirrhosis, and poorly controlled hypertension during pregnancy
Potential risk to the male fetus due to antiandrogenic properties of spironolactone; avoid spironolactone in pregnant women or advise a pregnant woman of the potential risk to a male fetus
Disease-associated maternal and embryo/fetal risks
- Pregnant women with CHF are at increased risk for preterm birth; stroke volume and heart rate increase during pregnancy, increasing cardiac output, especially during the first trimester; closely monitor pregnant patients with CHF
- Pregnant women with symptomatic cirrhosis generally have poor outcomes (eg, hepatic failure, variceal hemorrhage, preterm delivery, fetal growth restriction, and maternal death); pregnant women with cirrhosis of the liver should be monitored and managed accordingly
- Hypertension in pregnancy increases the maternal risk for preeclampsia, gestational diabetes, premature delivery, and delivery complications (eg, need for cesarean delivery, postpartum hemorrhage); hypertension increases the fetal risk for intrauterine growth restriction and death
Lactation
Not present in breastmilk; however, limited data from a lactating woman at 17 days postpartum reports the presence of the active metabolite, canrenone, in human breast milk in low amounts that are expected to be clinically inconsequential; in this case, there were no adverse effects reported for the breastfed infant after short term exposure to spironolactone; however, long term effects on a breastfed infant are unknown; there are no data on spironolactone effects on milk production
Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for the drug, and any potential adverse effects on the breastfed infant from the drug or from the underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Aldosterone antagonist with diuretic and antihypertensive effects; competitive binding of receptors at aldosterone-dependent Na-K exchange site in distal tubules results in increased excretion of Na+, Cl-, and water and retention of K+ and H+
Increases testosterone clearance and estradiol production; blocks conversion of potent androgens to weaker ones in peripheral tissues

Onset: 2-4 hr (tablet)
Duration: 2-3 days (tablet)
Peak serum time: 2.6-4.3 hr (tablet); 0.5-1.5 hr (PO suspension); 2.5-5 hr (PO suspension, active metabolite)
A high fat and high calorie meal (57% of the ~1000 kcal of the meal were from fat) increased the bioavailability of spironolactone (as measured by AUC) by ~90%
Distribution
Protein bound: 90%
