What conditions is spironolactone used to treat?
Spironolactone is used for several common medical purposes, most notably because it blocks aldosterone (a hormone that increases salt and water retention).
Doctors commonly prescribe it for:
- Heart failure: to help reduce fluid buildup and ease the workload on the heart.
- Edema (fluid retention) from conditions like liver disease: to reduce swelling caused by excess fluid.
- High blood pressure (hypertension), especially in people where aldosterone-related fluid retention is part of the problem.
How is spironolactone used for hormone-related conditions?
Spironolactone is also used for its anti-androgen effects (it can reduce the impact of male-type hormones). Common uses include:
- Acne (often in people with hormonal acne)
- Excess facial or body hair (hirsutism) in people with hormone imbalance
- Polycystic ovary syndrome (PCOS)-related symptoms such as acne or hirsutism
Can spironolactone be used as a diuretic (“water pill”)?
Yes. Spironolactone acts as a diuretic, helping the body get rid of extra fluid. It is often chosen when clinicians want a potassium-sparing diuretic rather than one that causes the body to lose potassium.
Are there key safety concerns with spironolactone?
A major patient concern is that it can raise potassium levels (hyperkalemia), which can be dangerous. Clinicians typically monitor potassium and kidney function, especially in people who:
- Have kidney disease
- Take other medicines that increase potassium
What should people ask their doctor when starting it?
People often want to know:
- Why it was chosen for them (heart, blood pressure, edema, or hormone-related symptoms)
- What lab monitoring is needed (potassium and kidney tests)
- Which other medications to avoid or adjust (especially those affecting potassium)
