From the Guidelines

Spironolactone is a recommended treatment for hormonal acne and female pattern hair loss, particularly in women of reproductive age, due to its ability to block androgen receptors and reduce sebum production, with a typical dosing range of 50-200mg daily. The use of spironolactone for acne treatment is supported by moderate certainty evidence from several studies, including a recent study published in 2024 1. This study found that spironolactone was effective in improving acne symptoms and quality of life in patients with acne, with a greater proportion of patients achieving treatment success compared to placebo.

Some key points to consider when using spironolactone for acne treatment include:

  • Typical dosing range: 50-200mg daily, with most patients starting at 50-100mg daily and adjusting based on response
  • Treatment duration: often long-term, with improvements typically seen after 3-6 months of consistent use
  • Common side effects: increased urination, menstrual irregularities, breast tenderness, and potential hyperkalemia
  • Monitoring: regular monitoring of potassium levels is recommended, especially in patients with kidney disease or those taking other potassium-sparing medications
  • Contraindications: spironolactone should not be used in pregnancy, and concurrent use of a combined oral contraceptive (COC) is often indicated to minimize the risk of menstrual irregularities and pregnancy.

Overall, spironolactone is a valuable treatment option for hormonal acne and female pattern hair loss, and its use should be considered in patients who are suitable candidates, particularly in light of the recent evidence supporting its efficacy and safety 1.

From the Research

Dermatological Uses of Spironolactone

  • Spironolactone is a synthetic aldosterone receptor antagonist with antiandrogenic properties, making it suitable for treating dermatological conditions caused by excess androgen production 2, 3.
  • The drug is used to treat various conditions, including:
    • Acne: Spironolactone is an effective alternative treatment for acne in women, particularly for hormonal acne 3, 4.
    • Hidradenitis suppurativa: Spironolactone has been shown to be useful in treating this condition 2, 5.
    • Female pattern hair loss: Spironolactone is used as a primary medical treatment for female pattern hair loss 3, 5.
    • Hirsutism: Spironolactone is used to treat hirsutism, with low-dose therapy showing excellent clinical response in some patients 6.

Mechanism of Action and Side Effects

  • Spironolactone exerts its antiandrogenic effects by reducing testosterone production and inhibiting its action on target tissues 3.
  • Common side effects of spironolactone include menstrual irregularities, such as polymenorrhea, and other hormonal changes 6.
  • The drug should not be used in pregnancy due to its teratogenic effects and is not recommended for men due to the risk of feminization 3.

Treatment Recommendations and Dosage

  • The dosage of spironolactone varies depending on the condition being treated and the individual patient's response 5.
  • Continuous treatment is required to sustain the effect of spironolactone, and patients should be monitored for potential adverse effects 3, 5.
