What to Expect from Spironolactone Treatment for Hirsutism

Spironolactone reduces some androgen effects on hair follicles. Hirsutism can have different causes, so your clinician may ask about periods, medicines, rapid changes in hair growth, acne, scalp hair thinning, and other signs before choosing treatment.

The medicine does not remove hairs already present. Over time, new growth may become slower or less coarse, while shaving, threading, waxing, electrolysis, or laser-based care may still be used when suitable. Possible effects include more urination, dizziness, breast tenderness, menstrual changes, and fatigue.

Take each dose as directed and attend reviews so your clinician can assess hair growth, blood pressure, and any needed laboratory monitoring. Mention kidney or adrenal conditions, low blood pressure, supplements, and medicines that affect potassium or fluid balance. Do not add potassium products without advice.

Keep a simple record of cycle changes and treatment effects. Ask which hair-removal method fits your skin and hair type, and avoid harsh approaches on irritated skin. If hair growth becomes sudden or progresses quickly, arrange assessment rather than relying only on cosmetic removal.

Contact your prescriber for severe dizziness, faintness, marked weakness, palpitations, persistent vomiting, or bleeding changes that are difficult to manage. Seek urgent care for collapse, chest pain, severe breathing difficulty, or swelling of the face or throat. Report possible pregnancy promptly so the prescription can be reviewed.

Ask what may be causing the excess hair, how long a fair treatment trial should be, whether tests or contraception are needed, and which removal methods can be combined. Clarify monitoring, missed doses, side effects, and what change in hair growth should prompt an earlier appointment.
