How does spironolactone therapy work?

Androgens can stimulate oil glands and influence hair follicles. Spironolactone reduces part of that signal and also has a water-balancing action. A clinician may consider it for adult acne, hormonal acne, hirsutism, or female pattern hair loss when the overall history fits. It is a prescription medicine, and response is gradual rather than immediate. Possible effects include breast tenderness, menstrual changes, dizziness, increased urination, and changes in blood potassium. The medicine is not suitable for everyone.

Tell the prescriber about kidney or adrenal problems, low blood pressure, pregnancy plans, breastfeeding, and every medicine or supplement you take. Some people need blood tests before or during treatment, especially when other medicines affect kidney function or potassium. Take it exactly as prescribed and do not change the dose because acne fluctuates. Keep follow-up visits so blood pressure, symptoms, periods, and treatment response can be reviewed. Hormone testing may be useful when symptoms suggest an underlying hormonal disorder.

Contact the prescriber for faintness, persistent vomiting, troublesome menstrual bleeding, or new breast symptoms. Seek urgent help for severe weakness, confusion, an irregular heartbeat, facial swelling, or breathing difficulty. Tell the clinician promptly if pregnancy occurs or is possible so the treatment plan can be reviewed.

Why is spironolactone appropriate for my pattern of acne or hair change? Do I need blood pressure checks or blood tests? Which medicines, supplements, and contraceptive options should I avoid or discuss?
