What is Aldactone?

Aldactone (spironolactone) is a potassium-sparing diuretic used for fluid retention in

  • Heart failure,
  • Liver cirrhosis,
  • Kidney disease.

It balances potassium levels and lowers blood pressure by blocking aldosterone receptors in the kidneys, increasing sodium and water excretion while retaining potassium.


What is the use of Aldactone?

Aldactone is used to treat various conditions including:

  • High blood pressure (Hypertension)
  • Heart failure
  • Low potassium levels in the blood (Hypokalemia)
  • Fluid retention (Edema) is associated with conditions such as congestive heart failure, liver cirrhosis, and nephrotic syndrome (kidney diseases).

It is also prescribed to diagnose disorders characterised by excess aldosterone, a hormone produced by the adrenal glands that regulates salt and water balance.

Frequently Asked Questions

What is Aldactone used for?

Lowering high blood pressure helps prevent strokes, kidney complications, and heart attacks. It is also used to treat swelling (edema) caused by some conditions by removing excess fluid and improving symptoms such as breathing issues (heart failure, liver disease).

What does Aldactone do to hormones?

Aldactone works by limiting hormonal changes that can trigger breakouts. Androgen hormones, including testosterone, are usually considered male hormones. Androgens, however, are also found in the female body, but at lower levels. Some women develop more androgen hormones than necessary.

How does Aldactone work?

Aldactone works against the effects of a hormone called aldosterone. Too much aldosterone allows the kidneys to maintain elevated levels of sodium (a mineral) and water, while too much potassium is eliminated from the body.

Is Aldactone bad for kidneys?

Aldactone can worsen kidney function in patients with low to no salt in their bodies or in those taking other blood pressure medicines (e.g., ARB, ACE inhibitor). If you have questions about this, talk to your doctor.

Is Aldactone a steroid?

It is a steroid that blocks and has some estrogen-like effects on the effects of the hormones aldosterone and testosterone. Aldactone belongs to a class of drugs known as diuretics that are potassium-sparing.
