Aldactone (Spironolactone)
Complete patient guide for uses, dosage, side effects, and safety information
Quick Facts
What Is Aldactone Used For?
Aldactone is a medication that contains spironolactone, which helps manage various health conditions by balancing certain hormones and fluids in the body.
Primary Uses
Aldactone is primarily used to treat essential hypertension, fluid retention (oedematous disorders), primary aldosteronism, malignant hypertension, low potassium levels, and hirsutism in women.
How It Works
Aldactone works by counteracting the effects of aldosterone, a hormone that causes the body to retain sodium and water while losing potassium. This helps lower blood pressure and reduce fluid retention.
Good to know: Aldactone is not considered addictive.
