Spironolactone
Aldosterone antagonist (potassium-sparing diuretic) for heart failure, hypertension and edema
Quick facts about Spironolactone
Key takeaways about Spironolactone
- Blocks aldosterone to reduce fluid retention: Spironolactone counteracts the hormone aldosterone, promoting sodium and water excretion while preserving potassium levels in the body
- Proven mortality benefit in heart failure: The landmark RALES trial demonstrated a 30% reduction in mortality when spironolactone was added to standard therapy for severe heart failure
- Regular potassium monitoring is essential: The most common side effect is hyperkalemia (high potassium), which can cause dangerous heart rhythm disturbances if not detected early
- Avoid potassium supplements and potassium-rich salt substitutes: Combining spironolactone with additional potassium sources significantly increases the risk of life-threatening hyperkalemia
- Take with food for best absorption: Spironolactone should be taken with meals to improve absorption and reduce gastrointestinal side effects
What Is Spironolactone and What Is It Used For?
Spironolactone is a potassium-sparing diuretic belonging to a class of medications called aldosterone antagonists. It works by blocking the effects of the hormone aldosterone, which normally causes the body to retain sodium (salt) and water. By counteracting aldosterone, spironolactone promotes the excretion of excess fluid while helping the body retain potassium.
Spironolactone is part of the renin-angiotensin-aldosterone system (RAAS), one of the body's most important regulatory systems for maintaining fluid and electrolyte balance. The hormone aldosterone is produced in the adrenal cortex and acts on the kidneys to increase sodium reabsorption and potassium excretion. When aldosterone levels are abnormally high or when the body retains too much fluid, spironolactone can help restore a healthier balance by blocking aldosterone's effects at the mineralocorticoid receptor.
The blood pressure-lowering effect of spironolactone depends primarily on the excretion of sodium and water. Unlike many other diuretics that cause potassium loss, spironolactone is classified as "potassium-sparing" because it reduces the amount of potassium lost in the urine. This property makes it particularly valuable in patients who need diuretic therapy but are at risk of low potassium levels (hypokalemia).
Spironolactone is included on the WHO Model List of Essential Medicines, recognizing its importance in global healthcare. It is approved and widely prescribed for several conditions:
- Fluid retention (edema) from heart disease: Spironolactone helps remove excess fluid that accumulates in the tissues when the heart is unable to pump effectively
- Moderate to severe heart failure (NYHA class III-IV): The landmark RALES trial (Randomized Aldactone Evaluation Study) published in the New England Journal of Medicine in 1999 demonstrated that adding spironolactone 25 mg daily to standard therapy reduced all-cause mortality by 30% in patients with severe heart failure
- High blood pressure (hypertension): Used as an add-on therapy in combination with a reduced-salt diet and other antihypertensive medications, particularly effective in resistant hypertension
- Certain kidney diseases (nephrotic syndrome): Helps manage the fluid retention and edema that can accompany kidney disease
- Fluid accumulation in the abdomen (ascites): Commonly used to treat ascites associated with liver cirrhosis, where aldosterone levels are typically elevated
- Primary hyperaldosteronism (Conn's syndrome): Used both as a diagnostic tool and treatment for conditions where the adrenal glands produce excessive amounts of aldosterone
In addition to its traditional uses as a diuretic, spironolactone has anti-androgenic properties because it also blocks androgen receptors. This means it can reduce the effects of male sex hormones, which has led to additional clinical applications in dermatology and endocrinology, although these uses are considered off-label in many countries.
Children should only be treated with spironolactone under the supervision of a pediatric specialist. Spironolactone may be approved for treating other conditions not listed in the standard product information. Always follow your doctor's instructions and consult a healthcare professional if you have questions about your treatment.
What Should You Know Before Taking Spironolactone?
Before starting spironolactone, your doctor needs to know about your kidney function, potassium levels, and all other medications you take. Spironolactone must not be used in several specific situations, including severe kidney impairment, high potassium levels, and Addison's disease. Regular blood monitoring is essential throughout treatment.
Contraindications
Spironolactone must not be taken in the following situations:
- Allergy to spironolactone or any of the inactive ingredients in the formulation
- Severe kidney impairment or rapidly worsening kidney disease, particularly when little or no urine is being produced (anuria)
- Low sodium levels in the blood (hyponatremia), as spironolactone can worsen this condition
- Addison's disease (adrenal insufficiency), a hormonal deficiency characterized by extreme weakness, weight loss, and low blood pressure
- Hyperkalemia (elevated potassium levels in the blood) or conditions that may lead to hyperkalemia
- Concurrent use of other potassium-sparing diuretics (including eplerenon) or potassium supplements
- Dual RAAS blockade with a combination of an ACE inhibitor (angiotensin-converting enzyme inhibitor) and an ARB (angiotensin receptor blocker)
Children with moderate to severe kidney disease must not take spironolactone. The risks of dangerous potassium accumulation are too high in this population.
Severe hyperkalemia can be life-threatening and may cause cardiac arrest. Patients with significantly impaired kidney function who also take potassium supplements are at the highest risk. Symptoms of severe hyperkalemia include muscle cramps, irregular heartbeat, diarrhea, nausea, dizziness, and headache. Report any of these symptoms to your doctor immediately.
Warnings and Precautions
Talk to your doctor or pharmacist before taking spironolactone if any of the following apply to you:
- You require regular monitoring of fluid and electrolyte levels, especially if you are elderly or have existing kidney or liver impairment
- You have difficulty urinating (urinary retention or obstruction)
- You have liver disease — your doctor will exercise caution when prescribing and may use lower doses
- You have kidney disease — dose adjustments and more frequent monitoring may be necessary
- You have severe heart failure — electrolyte imbalances are more common and potentially more dangerous
- You are taking other diuretics in combination, which may increase the risk of low sodium levels (hyponatremia)
- You have any condition that may disturb the balance of electrolytes (minerals such as potassium and sodium) in your blood
For long-term use in young patients, the doctor should carefully weigh the benefits against the potential long-term side effects, particularly hormonal effects such as gynecomastia (breast enlargement in males) and menstrual irregularities in females.
Pregnancy and Breastfeeding
If you are pregnant, breastfeeding, think you may be pregnant, or are planning to have a baby, consult your doctor or pharmacist before taking spironolactone.
- Pregnancy: Spironolactone should not be used during pregnancy unless the doctor considers it absolutely necessary. Due to its anti-androgenic properties, it may theoretically affect the development of a male fetus
- Breastfeeding: Spironolactone and its metabolites pass into breast milk. Breastfeeding is not recommended during treatment. Your doctor will advise on alternative feeding methods for your baby
- Fertility: Spironolactone can affect fertility in both men and women. It may cause erectile dysfunction and reduced libido in men, and menstrual irregularities in women. These effects are generally reversible upon discontinuation
Driving and Operating Machinery
Side effects such as dizziness, headache, and confusion may occasionally occur when using spironolactone. If you experience these effects, do not drive or operate machinery. You are personally responsible for assessing whether you are fit to drive or perform tasks that require alertness.
Spironolactone tablets contain lactose. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.
How Does Spironolactone Interact with Other Drugs?
Spironolactone interacts with many commonly prescribed medications. The most dangerous interactions involve drugs that also raise potassium levels, including ACE inhibitors, ARBs, potassium supplements, and other potassium-sparing diuretics. Always tell your doctor about all medications you are taking, including over-the-counter drugs and supplements.
Drug interactions with spironolactone can range from clinically insignificant to potentially life-threatening. The most important interactions relate to the risk of hyperkalemia (elevated potassium), changes in kidney function, and alterations in the blood levels or effects of other medications. Below is a comprehensive overview of the key drug interactions organized by clinical significance.
Major Interactions
The following drug interactions are considered clinically significant and may require dose adjustments, close monitoring, or avoidance of the combination entirely:
| Drug / Drug Class | Interaction Effect | Clinical Action |
|---|---|---|
| ACE inhibitors (e.g. enalapril, ramipril, lisinopril) | Increased risk of hyperkalemia and acute kidney injury | Monitor potassium and kidney function closely; dose adjustment may be needed |
| ARBs (e.g. losartan, valsartan, candesartan) | Increased risk of hyperkalemia, hypotension, and renal impairment | Dual RAAS blockade with ACE + ARB is contraindicated; close monitoring if combined |
| Potassium supplements | Severe hyperkalemia that may lead to cardiac arrest (potentially fatal) | Avoid combination; if necessary, closely monitor potassium levels |
| Eplerenone and other potassium-sparing diuretics | Additive potassium-retaining effect; dangerous hyperkalemia | Contraindicated — do not combine |
| Lithium | Reduced lithium excretion; risk of lithium toxicity | Monitor lithium levels closely; dose adjustment may be required |
| Heparin / Low-molecular-weight heparin | Both drugs can increase potassium levels | Monitor potassium levels regularly |
| Trimethoprim / Trimethoprim-sulfamethoxazole | Both drugs reduce potassium excretion; additive hyperkalemia risk | Monitor potassium closely; avoid if possible in high-risk patients |
| Ciclosporin (immunosuppressant) | Increased risk of hyperkalemia | Frequent potassium monitoring required |
| Mitotan (cancer treatment) | Mitotan may reduce spironolactone effectiveness | Contraindicated — do not use together |
Other Important Interactions
The following interactions are clinically relevant and should be considered when prescribing spironolactone:
| Drug / Drug Class | Interaction Effect | Clinical Action |
|---|---|---|
| NSAIDs (e.g. ibuprofen, aspirin, mefenamic acid) | Reduced diuretic and blood pressure-lowering effect; increased risk of hyperkalemia and kidney impairment | Use the lowest effective NSAID dose for the shortest duration; monitor kidney function |
| Digoxin | Spironolactone may increase digoxin blood levels and interfere with digoxin assays | Monitor digoxin levels; dose adjustment may be needed |
| Anticoagulants (blood thinners) | Altered anticoagulant effect | Monitor INR / coagulation more frequently |
| Other antihypertensives (including ganglion-blocking agents) | Enhanced blood pressure-lowering effect; risk of hypotension | Dose adjustment may be necessary; monitor blood pressure |
| Corticosteroids / ACTH | May counteract the potassium-sparing effect of spironolactone | Monitor electrolytes; dose adjustment may be needed |
| Noradrenaline (norepinephrine) | Reduced vascular response to noradrenaline | Caution during anesthesia and acute hypotension treatment |
| Alcohol, barbiturates, narcotics | Increased risk of orthostatic hypotension (dizziness on standing) | Rise slowly from sitting or lying position; limit alcohol intake |
| Cholestyramine | May reduce absorption of spironolactone | Take spironolactone at least 2 hours before cholestyramine |
| Abiraterone (prostate cancer treatment) | Potential pharmacological interaction | Inform your doctor if taking abiraterone |
If you are scheduled for surgery and will receive anesthesia, inform the anesthesiologist and your surgeon that you are taking spironolactone. The drug may interact with anesthetic agents and affect the vascular response to noradrenaline, which is used to manage blood pressure during surgery.
Food Interactions
Spironolactone should be taken with food to improve absorption. However, be mindful of the following dietary considerations:
- Potassium-rich foods: Limit consumption of bananas, oranges, potatoes, tomatoes, spinach, avocados, and dried fruits, as these can contribute to hyperkalemia when combined with spironolactone
- Salt substitutes: Many salt substitutes contain potassium chloride instead of sodium chloride. Avoid these products while taking spironolactone
- Licorice: Natural licorice contains glycyrrhizin (and its metabolite carbenoxolone), which can affect electrolyte balance. Discuss consumption with your doctor
What Is the Correct Dosage of Spironolactone?
The recommended dose of spironolactone varies depending on the condition being treated, typically ranging from 25 mg to 400 mg daily for adults. The standard starting dose is 100 mg per day, taken as a single dose or divided into multiple doses. Always take spironolactone with food and follow your doctor's specific dosing instructions.
Dosage recommendations for spironolactone vary considerably depending on the clinical indication, the severity of the condition, the patient's kidney function, and their response to treatment. Your doctor will determine the most appropriate dose for your individual situation. The information below provides general dosing guidance based on approved prescribing information.
Adults
The recommended starting dose for most adults is 100 mg daily, which may be given as a single dose or divided into multiple doses throughout the day. Depending on the condition being treated, the adult dose can range from 25 mg to 400 mg per day.
| Indication | Starting Dose | Usual Range | Notes |
|---|---|---|---|
| Edema (heart disease) | 100 mg/day | 25–200 mg/day | Single or divided doses; adjust based on response |
| Heart failure (NYHA III-IV) | 25 mg/day | 25–50 mg/day | Based on RALES trial; monitor potassium closely |
| Hypertension | 50–100 mg/day | 25–100 mg/day | Add-on to other antihypertensives; may take 2–4 weeks for full effect |
| Ascites (liver cirrhosis) | 100 mg/day | 100–400 mg/day | Often combined with furosemide in a 100:40 ratio |
| Primary hyperaldosteronism (Conn's syndrome) | 100–400 mg/day | 100–400 mg/day | Used for diagnosis and preoperative treatment |
When the total daily dose exceeds 100 mg, it should be divided into multiple doses spread throughout the day to maintain more consistent drug levels and reduce the risk of side effects. Tablets should always be taken with a meal to improve absorption.
Children
In children, the recommended dose is 3 mg per kilogram of body weight per day, divided into multiple doses. For example, a child weighing 20 kg would typically receive approximately 60 mg per day, split into 2–3 doses.
To make it easier for children to take spironolactone, tablets can be crushed and dissolved in a glass of water by stirring. Children should only be treated under the supervision of a pediatric specialist, and the prescribing doctor will monitor the child's kidney function and electrolyte levels regularly.
Elderly Patients
Elderly patients should start with the lowest possible dose, which is then gradually increased until the desired therapeutic effect is achieved. This cautious approach is necessary because older adults are more susceptible to electrolyte imbalances and kidney function changes. Regular medical check-ups are strongly recommended, particularly for patients with any degree of kidney impairment.
Missed Dose
If you forget to take a dose, take it as soon as you remember — unless it is nearly time for your next scheduled dose. In that case, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a forgotten one. If you are unsure about what to do, consult your doctor or pharmacist.
For the best results, try to take your medication at the same time each day. This helps maintain consistent drug levels in your body and makes it easier to remember your doses.
Overdose
If you have taken too much spironolactone, or if a child has accidentally swallowed the medication, contact your doctor, pharmacist, hospital, or poison control center immediately. Keep the medication package so healthcare professionals can identify what was taken.
Symptoms of overdose may include:
- Nausea and vomiting
- Drowsiness and confusion (rare)
- Diarrhea
- Skin rash with flat red areas and small raised bumps
- Disturbances of fluid and salt balance, including dehydration
- Weakness, tingling, numbness, and muscle spasms (from electrolyte imbalances)
If you stop taking spironolactone, the original symptoms of your condition may return. Always consult your doctor before discontinuing this medication. Your doctor may recommend a gradual dose reduction rather than an abrupt stop, depending on your medical condition.
What Are the Side Effects of Spironolactone?
Like all medicines, spironolactone can cause side effects, although not everyone experiences them. The most common side effect is hyperkalemia (elevated potassium in the blood), which occurs in more than 1 in 10 users. Other common effects include dizziness, nausea, skin rash, muscle cramps, and breast enlargement in men. Seek immediate medical attention if you experience signs of a severe allergic reaction or irregular heartbeat.
Side effects are listed below by how frequently they occur. It is important to understand that most people taking spironolactone do not experience serious side effects, and many side effects are dose-dependent, meaning they are more likely at higher doses. Regular monitoring of blood tests helps detect potential problems early, before they become clinically significant.
Severe skin reactions including itching and blistering around the lips and body (Stevens-Johnson syndrome), peeling of the skin (toxic epidermal necrolysis), or skin rash with fever and swelling (DRESS syndrome). Also seek immediate care for yellowing of the skin and eyes (jaundice), irregular heartbeat, tingling, paralysis, or breathing difficulties, which may indicate dangerously high potassium levels. Your doctor will regularly take blood samples to monitor potassium and electrolyte levels.
Very Common
May affect more than 1 in 10 people
- Hyperkalemia (elevated potassium levels in the blood)
Common
May affect up to 1 in 10 people
- Confusion

- DRESS syndrome (drug reaction with eosinophilia and systemic symptoms)
Many side effects of spironolactone are dose-dependent and reversible upon dose reduction or discontinuation. Hormonal side effects such as gynecomastia, menstrual irregularities, and changes in libido are related to the anti-androgenic properties of the drug and are more common at higher doses and with longer durations of treatment.
If you experience any side effects, including those not listed above, report them to your doctor or pharmacist. Reporting helps healthcare systems continuously monitor the benefit-risk balance of medications.
How Should You Store Spironolactone?

Frequently Asked Questions About Spironolactone
Spironolactone is a potassium-sparing diuretic (aldosterone antagonist) used to treat fluid retention (edema) from heart disease, moderate to severe heart failure (NYHA class III-IV), high blood pressure as an add-on therapy, certain kidney diseases, fluid accumulation in the abdomen (ascites from liver cirrhosis), and conditions with excess aldosterone production such as Conn's syndrome (primary hyperaldosteronism). It works by blocking the hormone aldosterone, which helps the body excrete excess sodium and water while retaining potassium.
The most common side effect is hyperkalemia (elevated potassium in the blood), which occurs in more than 1 in 10 users. Common side effects (affecting up to 1 in 10 users) include confusion, dizziness, nausea, skin itching and rash, muscle or bone cramps, kidney dysfunction, breast enlargement in men (gynecomastia), breast tenderness, and general malaise. Regular blood tests are needed to monitor potassium levels and kidney function. Many side effects are dose-dependent and reversible upon dose adjustment.
Spironolactone can be combined with ACE inhibitors or ARBs under careful medical supervision, and this combination is actually recommended in heart failure guidelines (e.g., ESC guidelines). However, dual RAAS blockade with both an ACE inhibitor and an ARB is contraindicated when spironolactone is also used. The combination increases the risk of hyperkalemia and requires close monitoring of potassium levels and kidney function, with blood tests typically performed within the first week and then regularly thereafter. Your doctor will determine the safest combination for your specific condition.
The diuretic effect of spironolactone typically begins within 2–3 days, but the full therapeutic effect for conditions like heart failure or hypertension may take 2–4 weeks to develop. The blood pressure-lowering effect builds gradually as sodium and water balance adjusts. For heart failure, the mortality benefit demonstrated in clinical trials develops over weeks to months of continuous therapy. Your doctor may adjust the dose over several weeks to find the optimal amount for your condition.
Spironolactone should not be used during pregnancy unless the doctor considers it absolutely necessary. Due to its anti-androgenic properties, spironolactone may theoretically affect the development of a male fetus. It also passes into breast milk, so breastfeeding is not recommended while taking this medication. Women planning pregnancy should discuss alternative treatments with their doctor. Spironolactone can also affect fertility by causing menstrual irregularities in women and erectile dysfunction in men, though these effects are generally reversible after stopping the medication.
While taking spironolactone, you should be cautious with foods high in potassium to reduce the risk of hyperkalemia. These include bananas, oranges, potatoes, tomatoes, spinach, avocados, dried fruits, and coconut water. You should also avoid salt substitutes containing potassium chloride and be careful with natural licorice products. Your doctor or dietitian may provide specific dietary guidance based on your individual potassium levels. Regular blood monitoring helps determine whether dietary restrictions are needed. Spironolactone itself should always be taken with food to improve absorption.
