Aldactone

Generic name: Spironolactone

Usage of Aldactone

Aldactone is a potassium-sparing diuretic (water pill) that prevents your body from absorbing too much salt and keeps your potassium levels from getting too low.

Aldactone is used to treat heart failure, high blood pressure (hypertension), or hypokalemia (low potassium levels in the blood).

Aldactone also treats fluid retention (edema) in people with congestive heart failure, cirrhosis of the liver, or a kidney disorder called nephrotic syndrome.

Aldactone is also used to diagnose or treat a condition in which you have too much aldosterone in your body. Aldosterone is a hormone produced by your adrenal glands to help regulate the salt and water balance in your body.

Aldactone side effects

Get emergency medical help if you have signs of an allergic reaction to Aldactone: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Call your doctor at once if you have:

  • a light-headed feeling, like you might pass out;
  • little or no urination;
  • high potassium level - nausea, weakness, tingly feeling, chest pain, irregular heartbeats, loss of movement; o
  • signs of other electrolyte imbalances - increased thirst or urination, confusion, vomiting, muscle pain, slurred speech, severe weakness, numbness, loss of coordination, feeling unsteady.

    • Common Aldactone side effects may include:

  • breast swelling or tenderness.

    • This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

    Before taking Aldactone

    You should not use Aldactone if you are allergic to spironolactone, or if you have:

  • Addison's disease (an adrenal gland disorder);
  • high levels of potassium in your blood (hyperkalemia);
  • if you are unable to urinate; or
  • if you are also taking eplerenone.

    • To make sure Aldactone is safe for you, tell your doctor if you have:

  • an electrolyte imbalance (such as low levels of calcium, magnesium, or sodium in your blood);
  • kidney disease;
  • liver disease; or
  • heart disease.

    • Tell your doctor if you are pregnant or plan to become pregnant. Having congestive heart failure, cirrhosis, or uncontrolled high blood pressure during pregnancy may lead to medical problems in the mother or the baby. Your doctor should decide whether you take Aldactone if you are pregnant.

    It may not be safe to breastfeed while using this medicine. Ask your doctor about any risk.

    How to use Aldactone

    Usual Adult Dose of Aldactone for Edema:

    25 to 200 mg orally per day in single or divided doses

    Duration of therapy: When given as the sole diuretic, continue the initial dose for at least 5 days, after which the initial dose may be adjusted to an optimal maintenance dose.

    Comments:

    -A second diuretic that acts more proximally at the renal tubule may be added if adequate diuresis has not been achieved after 5 days. The dose of this drug should remain unchanged if a second diuretic is added.

    Uses:

    -Treatment of edematous conditions in patients with congestive heart failure who are only partially responsive to or intolerant of other therapeutic measures or who are taking digitalis when other therapies are considered inappropriate.

    -Treatment of edematous conditions in patients with liver cirrhosis accompanied by edema and/or ascites.

    -Treatment of edematous conditions in patients with nephrotic syndrome when treatment of the underlying disease, restriction of fluid and sodium intake, and the use of other diuretics do not provide an adequate response.

    Usual Adult Dose of Aldactone for Hypertension:

    Initial dose: 50 to 100 mg orally per day in single or divided doses

    Duration of therapy: Treatment should be continued for at least 2 weeks to achieve a maximum response. Subsequently, the dose may be adjusted according to patient response.

    Usual Adult Dose for Congestive Heart Failure:

    Initial dose: 25 mg orally once a day assuming serum potassium is less than or equal to 5 mEq/L and serum creatinine is less than or equal to 2.5 mg/dL

    Maintenance dose:

    -Patients tolerant of initial dose: May increase to 50 mg orally once a day as clinically indicated

    -Patients intolerant of initial dose: May decrease to 25 mg orally every other day

    Use: To increase survival and reduce the need for hospitalization of severe heart failure patients (New York Heart Association [NYHA] class III to IV) when used in addition to standard therapy.

    Usual Adult Dose for Primary Hyperaldosteronism:

    Diagnostic dose:

    -Long test: 400 mg orally per day for 3 to 4 weeks

    -Short test: 400 mg orally per day for 4 days

    Maintenance dose: 100 to 400 mg orally per day until surgery; may be used long-term at the lowest effective dose in patients deemed unsuitable for surgery.

    Comments:

    -For the long test, correction of hypokalemia and hypertension provides presumptive evidence of primary hyperaldosteronism.

    -For the short test, increased serum potassium with this drug and a decrease upon discontinuation provide presumptive evidence of primary hyperaldosteronism.

    Uses:

    -Initial diagnostic measure to provide presumptive evidence of primary hyperaldosteronism while patients are on normal diets.

    -Short-term preoperative treatment of patients with primary hyperaldosteronism.

    -Long-term maintenance therapy for patients deemed unsuitable for surgery or those with idiopathic hyperaldosteronism.

    Usual Adult Dose for Hypokalemia:

    25 to 100 mg orally per day

    Uses:

    -Treatment of patients with hypokalemia when other measures are considered inappropriate or inadequate.

    -Prophylaxis of hypokalemia in patients taking digitalis when other measures are considered inadequate or inappropriate.

    Warnings

    You should use Aldactone with caution if you have kidney problems, high levels of potassium in your blood, Addison's disease, if you are unable to urinate, or if you are also taking eplerenone.

    Aldactone has caused tumors in animals but it is not known whether this could occur in people. Do not use this medicine for any condition that has not been checked by your doctor.

    What other drugs will affect Aldactone

    Using Aldactone with other drugs that make you dizzy can worsen this effect. Ask your doctor before using opioid medication, a sleeping pill, a muscle relaxer, or medicine for anxiety, depression, or seizures.

    Tell your doctor about all your other medicines, especially:

  • colchicine;
  • digoxin;
  • lithium;
  • loperamide;
  • trimethoprim;
  • heart or blood pressure medicine (especially another diuretic);
  • medicine to prevent a blood clot; or
  • NSAIDs (nonsteroidal anti-inflammatory drugs) - aspirin, ibuprofen (Advil, Motrin), naproxen (Aleve), celecoxib, diclofenac, indomethacin, meloxicam, and others.
