What is spironolactone used for?
Spironolactone is a prescription medicine used for several conditions, mainly related to salt/fluid balance and hormones. It’s commonly prescribed as a diuretic (a “water pill”) and as an anti-androgen (it blocks the effects of certain male-type hormones).
Why do doctors prescribe it as a “water pill”?
Spironolactone helps your kidneys remove extra salt and water while keeping potassium from being lost. That’s why it is often used for:
- Swelling (edema) from conditions such as heart failure
- Fluid buildup related to liver disease (ascites)
- Some cases of high blood pressure, especially when other options aren’t enough or when potassium loss would be a concern
What hormone-related uses does spironolactone have?
Because it blocks androgen effects, spironolactone is also used for:
- Hormonal acne (particularly in people who have androgen-driven acne)
- Hirsutism (excess body/facial hair in people with higher androgen activity)
- Female-pattern hair loss in some patients (commonly off-label depending on the country and clinician)
Is it used in breast cancer treatment?
Spironolactone is sometimes used in breast cancer contexts as an anti-androgen in selected situations, but it is not a first-line standard therapy for most breast cancers. Whether it’s used depends on the specific diagnosis and treatment plan.
What should patients watch for while taking it?
A key safety issue is that spironolactone can raise potassium levels. Clinicians monitor potassium and kidney function, especially in people who:
- Have kidney disease
- Take other medications that increase potassium (or certain blood pressure drugs like ACE inhibitors/ARBs)
- Are older or dehydrated
Common side effects can include dizziness, increased urination, breast tenderness, and menstrual changes.
