Does spironolactone work for acne?
Established. Slow to start, reliable to maintain. The 2023 SAFA trial, a pragmatic double-blind randomised trial of 410 women in England and Wales published in the BMJ, found spironolactone improved acne-related quality of life and participant-reported improvement compared with placebo at 12 and 24 weeks.
- Verdict
- Established Long clinical track record. Results depend on selection and technique more than on the device.
- Evidence base
- 3 PubMed-indexed studies cited below, including randomised trials, guidelines.
- Suits
- Adult women with persistent or hormonally patterned acne — jawline, chin, premenstrual flares — who want to avoid repeated antibiotics and can wait three to six months for the effect.
- Not for
- Men; pregnancy or planned pregnancy without reliable contraception; kidney disease or high potassium; people on medicines that raise potassium without medical review.
- In Singapore
- Spironolactone is prescription-only in Singapore and used off-label for acne, prescribed after assessment.

What it is
Spironolactone is an old blood-pressure and fluid medicine that also blocks androgen receptors in the skin. At low to moderate doses it reduces oil production and the hormonally driven acne common along the jaw and chin in adult women. It is prescription-only and is not used in men for acne.
How it works
By blocking androgen effects on the sebaceous gland, it lowers sebum and the inflammatory acne that follows. Improvement builds over three to six months and the medicine is continued as maintenance. It is often combined with topical treatment, and sometimes with a combined oral contraceptive.
What the evidence says
The 2023 SAFA trial, a pragmatic double-blind randomised trial of 410 women in England and Wales published in the BMJ, found spironolactone improved acne-related quality of life and participant-reported improvement compared with placebo at 12 and 24 weeks. A 2024 randomised trial in adult women found spironolactone at least as effective as doxycycline. The 2024 AAD guideline recommends it for women with acne. Routine potassium monitoring is not needed in healthy young women.

What the studies show
- RCT
In 410 women with persistent acne, spironolactone improved acne-specific quality of life and self-assessed improvement versus placebo, with benefit more evident at 24 weeks.

- RCT
Spironolactone was at least as effective as doxycycline for moderate acne in adult women.

Who it suits
Suits
Adult women with persistent or hormonally patterned acne — jawline, chin, premenstrual flares — who want to avoid repeated antibiotics and can wait three to six months for the effect.
Not for
Men; pregnancy or planned pregnancy without reliable contraception; kidney disease or high potassium; people on medicines that raise potassium without medical review.
Alternatives
The two reviewed treatments most often weighed against Spironolactone for adult female acne, on the same standard.
| Spironolactone for adult female acne | Isotretinoin for acne | Oral antibiotics for acne | |
|---|---|---|---|
| Verdict | Established | Established | Established |
| What it is | Spironolactone is an old blood-pressure and fluid medicine that also blocks androgen receptors in the skin. | Isotretinoin is an oral retinoid, a vitamin A derivative, prescribed for severe or scarring acne and for moderate acne that has not responded to other treatment. | Tetracycline-class antibiotics — doxycycline, minocycline, lymecycline and the newer narrow-spectrum sarecycline — taken by mouth for moderate to severe inflammatory acne. |
| Evidence base | 3 PubMed-indexed studies cited below, including randomised trials, guidelines. | 4 PubMed-indexed studies cited below, including systematic reviews, meta-analyses, randomised trials. | 4 PubMed-indexed studies cited below, including meta-analyses, randomised trials, guidelines. |
| Suits | Adult women with persistent or hormonally patterned acne — jawline, chin, premenstrual flares — who want to avoid repeated antibiotics and can wait three to six months for the effect. | Severe, nodular or scarring acne; moderate acne that has failed topicals and oral antibiotics; adults with persistent acne who accept monitoring and, for women, strict contraception. | Moderate to severe inflammatory acne — red papules and pustules on the face, chest or back — as a time-limited course alongside a topical retinoid or benzoyl peroxide, prescribed and reviewed by a doctor. |
| In one line | Slow to start, reliable to maintain. | The side effects are real and mostly manageable; the pregnancy rule is absolute. | Three months with a retinoid alongside is the job; if acne returns each time it stops, the next conversation is isotretinoin or, for women, spironolactone. |
Risks
Menstrual irregularity, breast tenderness, increased urination, dizziness from lower blood pressure; raised potassium in people with kidney disease or interacting drugs; must not be taken in pregnancy.
In Singapore
Spironolactone is prescription-only in Singapore and used off-label for acne, prescribed after assessment. It may not be advertised to the public; this review names it generically for information.
