Common Uses of Aldactone (Spironolactone)
Aldactone (spironolactone) is a potassium‑sparing diuretic and selective aldosterone antagonist widely used to reduce fluid overload and lower blood pressure. Clinicians prescribe it as add‑on therapy for hypertension, for symptoms and survival benefits in certain patients with heart failure, and to relieve edema related to cirrhosis or nephrotic syndrome. By blocking aldosterone at the distal nephron, Aldactone promotes sodium and water excretion while conserving potassium, helping decrease swelling, breathlessness, and ascites. It is also a cornerstone for diagnosing and treating primary hyperaldosteronism, both short‑term (pre‑surgical) and long‑term when surgery is not possible.
Aldactone’s antiandrogenic activity provides benefits beyond cardiometabolic care. Dermatology clinicians use spironolactone off‑label to treat hormonal acne, especially jawline and cystic flares, reduce hirsutism, and address androgen‑driven symptoms in polycystic ovary syndrome in appropriate candidates. It is sometimes incorporated as an antiandrogen in gender‑affirming care under specialist supervision. Because response and tolerability vary, dosing is individualized and paired with periodic bloodwork. Patients often notice gradual improvement in oiliness, breakouts, and unwanted hair growth over several months, a timeline consistent with hair and pilosebaceous cycles. Contraception is advised because spironolactone may affect a developing male fetus in early pregnancy.
Dosage and Direction: How to Take Aldactone Safely
Spironolactone dosing is tailored to the condition being treated, kidney function, concomitant drugs, and potassium levels. For hypertension, typical oral doses range from 25–100 mg daily, given once or in divided doses. In chronic heart failure with reduced ejection fraction, many patients start at 12.5–25 mg daily and titrate to 25–50 mg as tolerated while monitoring potassium and creatinine. Edema due to cirrhosis or nephrotic syndrome may require 25–200 mg daily, adjusted gradually to the minimum effective dose. Primary hyperaldosteronism often calls for higher doses (100–400 mg/day) during evaluation or when surgery is not feasible, under close specialist supervision. Pediatric and geriatric dosing require individualized adjustments.
To support steady absorption, take Aldactone at the same time each day, preferably with food. Because it increases urination, morning or early‑afternoon dosing helps reduce nighttime bathroom trips. Do not change your dose, stop, or start related meds like ACE inhibitors, ARBs, or potassium supplements without clinician guidance. Routine monitoring is essential: adults need baseline electrolytes and kidney function, a repeat check within 3–7 days after initiation or dose increases, again at 1 month, and then periodically. Follow sodium and fluid recommendations from your care team, and maintain a moderate‑potassium diet unless otherwise directed.
Precautions for Aldactone: What to Know Before and During Treatment
Spironolactone can raise serum potassium, especially in people with chronic kidney disease, diabetes, older age, or those taking ACE inhibitors, ARBs, aliskiren, trimethoprim, or potassium supplements. Hyperkalemia can be silent or present with weakness, paresthesias, or abnormal heart rhythms; lab monitoring is the best protection. Dehydration, low blood pressure, and kidney injury may occur if diuresis is too brisk, during vomiting/diarrhea, or when combined with NSAIDs; your prescriber may adjust the dose or temporarily hold therapy during acute illness. Avoid high‑potassium salt substitutes and be cautious with very high‑potassium diets unless specifically instructed.
Hormonal effects can occur with Aldactone, including breast tenderness or enlargement (gynecomastia), menstrual irregularities, spotting, decreased libido, and erectile dysfunction. Dizziness, fatigue, and headache are possible; stand up slowly to reduce orthostatic symptoms. Spironolactone may affect a developing male fetus; avoid use in pregnancy and discuss reliable contraception. Limited amounts of active metabolites may appear in breast milk—share lactation plans with your clinician to weigh risks and benefits. Use sun protection if you notice photosensitivity. If you are undergoing testing for renin/aldosterone disorders, your specialist may pause Aldactone beforehand to avoid confounding results. Limit alcohol intake, which can worsen dizziness and lower blood pressure unexpectedly during therapy.
Contraindications: Who Should Not Take Aldactone
Do not use Aldactone if you have known hypersensitivity to spironolactone or any component of the formulation, anuria, acute renal failure, or baseline hyperkalemia. Clinically significant renal impairment (for example, eGFR below approximately 30 mL/min/1.73 m²) greatly increases the risk of life‑threatening hyperkalemia and is generally a contraindication outside specialist care. Aldactone is contraindicated in Addison’s disease and other conditions associated with high potassium. Concomitant use with another aldosterone antagonist such as eplerenone is typically avoided. Pregnancy is not an absolute contraindication in every context, but potential antiandrogenic effects on a male fetus mean spironolactone should generally be avoided unless a specialist determines that benefits clearly outweigh risks. Do not use with potassium supplements in untreated hyperkalemia or severe dehydration.
Possible Side Effects of Aldactone
Many people tolerate Aldactone well, but side effects can occur. Commonly reported effects include increased urination, dizziness or lightheadedness, fatigue, headache, gastrointestinal upset (nausea, diarrhea, stomach cramps), and breast tenderness or enlargement. Menstrual changes and spotting, decreased libido, erectile dysfunction, and acne improvement or, rarely, a transient flare may be seen as hormones rebalance. Some people notice muscle cramps or mild skin rash. Because spironolactone is potassium‑sparing, elevated potassium is the most clinically important risk; symptoms can include weakness, tingling, palpitations, or, rarely, dangerous heart rhythm disturbances—seek medical care urgently if these occur. Hypotension can manifest as faintness when standing; staying hydrated and rising slowly can help. Less commonly, hyponatremia may cause confusion, seizures, or severe fatigue in vulnerable patients.
Serious adverse reactions are uncommon but possible: profound hyperkalemia, severe allergic reactions, Stevens‑Johnson syndrome, agranulocytosis or other blood dyscrasias, liver enzyme elevations, or sudden kidney function decline. Report yellowing of the eyes, dark urine, easy bruising, fever, persistent sore throat, or a widespread blistering rash immediately. Dose‑related gynecomastia can occur, particularly at higher doses or prolonged use. Rarely, women report voice deepening. If side effects are troublesome, clinicians can adjust the dose, change timing, or consider alternatives; never stop abruptly in heart failure without medical advice or specialist heart care.
Aldactone Drug Interactions to Watch
Aldactone’s potassium‑sparing effect makes interactions that raise potassium particularly important. Combining spironolactone with ACE inhibitors, ARBs, aliskiren, drospirenone‑containing oral contraceptives, potassium supplements, potassium salt substitutes, or high‑dose trimethoprim (alone or in TMP‑SMX) can precipitate dangerous hyperkalemia. Calcineurin inhibitors (cyclosporine, tacrolimus) and heparin products can also increase potassium. Nonsteroidal anti‑inflammatory drugs may blunt diuretic effect, reduce kidney perfusion, and raise potassium when used chronically—avoid routine NSAID use unless instructed. Dual therapy with eplerenone or high‑dose amiloride/triampterene is generally avoided due to additive risk. Spironolactone may increase digoxin levels and reduce renal clearance of lithium, heightening toxicity risk—monitor closely or avoid. When combined with other diuretics, blood pressure can drop more than expected. Alcohol or sedatives can intensify dizziness and orthostatic symptoms.
Spironolactone can interfere with diagnostic testing for renin and aldosterone; specialists may instruct a washout period before testing. Some lab assays for digoxin are also susceptible to interference. Always give your clinician and pharmacist an up‑to‑date list of all prescriptions, over‑the‑counter drugs, supplements, and herbal products. After any medication change that could affect potassium or kidney function, arrange follow‑up labs within the recommended window and watch for symptoms such as new weakness, palpitations, or marked reductions in urination or swelling.
Missed Dose: What to Do with Aldactone
If you miss a dose of Aldactone, take it as soon as you remember unless it is close to your next scheduled dose. If it is almost time, skip the missed dose and resume your regular schedule. Do not double up. To avoid nighttime urination, avoid taking a catch‑up dose late in the evening. Set reminders to improve adherence daily.
Overdose: When Aldactone Requires Emergency Help
Overdose may cause profound drowsiness, confusion, nausea, vomiting, dizziness, low blood pressure, dehydration, abnormal heart rhythms, and dangerous hyperkalemia. This is a medical emergency. Call emergency services or poison control immediately and do not attempt to self‑treat. Bring a list of medications. Management focuses on supportive care, monitoring, and rapid correction of electrolytes and volume status under hospital supervision only.
Storage: How to Store Aldactone Properly
Store Aldactone tablets at room temperature, ideally 20–25°C (68–77°F), protected from moisture, heat, and light. Keep the bottle tightly closed and use the original container with desiccant when provided. Do not store in bathrooms or vehicles. Keep out of reach of children and pets. Safely discard expired or unused medication per local guidance or pharmacy take‑back program instructions when available.
