Detailed definition
Spironolactone is a competitive aldosterone receptor antagonist (potassium-sparing diuretic) and androgen receptor antagonist. Its antiandrogenic activity is exploited off-label for female pattern hair loss, hirsutism, and persistent adult acne. Typical dermatology doses are 50–200 mg daily, often added to topical minoxidil for hair loss. Side effects include hyperkalemia (monitor potassium, especially in older women or those on ACE inhibitors), menstrual irregularity, breast tenderness, and rarely hyponatremia. Pregnancy is a contraindication due to feminization risk in male fetuses. Combined with HRT, spironolactone can address overlapping androgen-related complaints; the combination is generally well-tolerated.
Why it matters in menopause
For women whose midlife complaints include thinning hair plus chin or upper-lip hair plus acne, spironolactone addresses the cluster more comprehensively than minoxidil alone. ClearedRx may coordinate with dermatology when these complaints are prominent.
