PCOS / PMOS treatment options : options to discuss, not a prescription

This guide presents the therapeutic options available in PCOS / PMOS management. It makes no personal recommendations: appropriate treatments depend on your symptoms, your profile, your goals, and your medical context. Only your doctor can guide your care.

For information only. Nothing on this page constitutes a prescription, a personal therapeutic recommendation, or an inducement to change a current treatment. Never start or stop a treatment without your doctor's advice.

No single treatment, goal-based management

PCOS is a multi-symptom syndrome: cycle irregularities, hyperandrogenism (acne, hirsutism, alopecia), insulin resistance, anovulation, psychological impact. There is no treatment that addresses all these dimensions simultaneously. Management is built around objectives — based on what matters most to you at a given point in your life.

This is one of the key recommendations of the Monash 2023 international guideline: aligning management with the patient's priorities and preferences.

A chronic condition, not a disease to be cured

There is no treatment that “cures” PCOS / PMOS. It is a hormonal and metabolic condition that is managed over time. This does not mean nothing can improve — on the contrary, symptoms often respond well to appropriate management. But beware of promises of complete resolution, particularly on social media or in non-medical wellness spaces.

For cycles and skin

Combined hormonal contraceptives (CHC)

CHCs (combined pill, vaginal ring, patch) are the most widely used treatments for regulating cycles, reducing bleeding, improving acne, and decreasing hirsutism in PCOS. They work by suppressing ovarian androgen production and increasing SHBG, thereby reducing the free fraction of testosterone.

They are not appropriate for all situations. Main contraindications include history of thromboembolic events, certain migraines with aura, smoking over age 35, and uncontrolled hypertension. The choice of progestogen can influence effects on skin and mood — discuss this with your doctor based on your history.

Progestogen-only options

Progestogen-only options (mini-pill, hormonal IUD) may be offered when oestrogens are contraindicated. They can induce cycle regulation in certain situations, but their effect on hyperandrogenism is generally less pronounced than that of CHCs.

For the metabolic dimension

Metformin

Metformin is a biguanide medication, historically used in type 2 diabetes. In PCOS, it may be offered to improve insulin sensitivity, reduce insulin levels, and thereby improve cycle regularity and reduce certain androgenic parameters. It is also used in some fertility protocols.

Its most common side effects are gastrointestinal (nausea, diarrhoea) — generally transient and reduced by starting at a low dose. Regular biological monitoring (kidney function in particular) is standard. The decision to prescribe it, the dose and duration belong to your doctor.

Inositol

Myo-inositol and D-chiro-inositol are dietary supplements studied in PCOS for their effects on insulin sensitivity and cycle regularity. The level of evidence remains moderate — existing studies are often small and short-term. These are not medications and do not substitute for medical treatment when it is indicated. Mention it to your doctor if you are considering taking them.

For fertility

PCOS is the leading cause of anovulatory infertility, but the majority of affected women succeed in conceiving with medical support. Therapeutic options are stepwise:

Letrozole: first-line medication for ovulation induction in PCOS, according to the Monash 2023 guideline. Higher pregnancy rate per cycle than clomiphene. In the landmark Legro et al. 2014 RCT (NEJM), letrozole achieved a live birth rate of 27.5% per cycle compared with 19.1% for clomiphene in women with PCOS.
Clomiphene citrate: a classic alternative, used as second-line since publication of comparative data with letrozole.
Gonadotrophins (FSH/hMG): injectable, used if letrozole is ineffective or in IVF protocols. Require close ultrasound monitoring due to risk of ovarian hyperstimulation.
IVF / ICSI: third-level management, indicated based on the couple's full fertility workup.
Laparoscopic ovarian drilling: a surgical procedure (cauterisation of several ovarian follicles) that can restore spontaneous ovulation. Indicated in specific situations; less commonly used since the advent of medical treatments.

For hyperandrogenism

When androgenic symptoms (hirsutism, androgenic acne, alopecia) are pronounced and inadequately controlled by CHCs, anti-androgen treatments may be offered as an adjunct or alternative:

Spironolactone: a diuretic with anti-androgenic properties, used off-label for this indication. Requires effective contraception (potential teratogen) and biological monitoring (potassium, kidney function).
Cyproterone acetate: an anti-androgenic progestogen, often integrated into certain combined pills or used alone in sequential regimens. Long-term hepatic monitoring is recommended.
Finasteride: a 5-alpha-reductase inhibitor, used off-label for refractory hirsutism. Contraindicated in case of pregnancy plans.

All of these medications require effective contraception during use and regular medical monitoring.

For the skin: dermatological approaches

Skin management in PCOS often involves a combined medical and dermatological approach:

Topicals: retinoids, benzoyl peroxide, azelaic acid — used locally for acne. Their efficacy is enhanced by systemic hormonal treatment.
Isotretinoin: reserved for severe or treatment-resistant acne, under strict prescription and monitoring (mandatory contraception, regular blood tests).
Laser / IPL (intense pulsed light): for excess hair growth. Well documented efficacy for lasting hair reduction, as an adjunct or alternative to medication.
Minoxidil (topical or oral): for androgenic alopecia. Long-term treatment; variable efficacy between patients; discuss with a dermatologist.

Dietary supplements

Several supplements are frequently mentioned in the context of PCOS: inositol, vitamin D (often deficient in PCOS), omega-3, N-acetylcysteine (NAC). Their level of evidence varies. None substitute for medical treatment when it is indicated, and some may interact with medications. Before starting any, mention it to your doctor.

The holistic approach

Medical treatments are more effective when embedded in comprehensive management: regular physical activity, a balanced diet adapted to the individual, quality sleep, stress management, and psychological support if needed. These elements do not replace treatments — they potentiate them.

Prepare my appointment Questions for my doctor

Frequently asked questions

Can PCOS be cured?

No, in the medical sense of the word. PCOS / PMOS is a chronic condition — it does not disappear but can be managed. Symptoms can improve significantly with appropriate management: regular cycles, reduced acne and hirsutism, improved fertility, metabolic stabilisation. After menopause, some symptoms (irregular cycles) naturally resolve, but metabolic risks remain and warrant continued monitoring.

Do I always need to take the pill with PCOS?

No. Combined hormonal contraceptives are one option among several, useful for regulating cycles and treating acne or hirsutism in patients who do not wish to conceive. They are not appropriate for all situations (vascular contraindications, pregnancy plans, intolerance). Other options exist depending on symptoms. It is a decision to make with your doctor based on your goals and profile.

How long is metformin taken for?

There is no universal duration. Metformin is prescribed for specific indications (documented insulin resistance, impaired glucose tolerance, certain cases of infertility or hirsutism), and the duration depends on the indication, clinical response, and biological monitoring. Some patients take it for years, others for a limited period. The decision belongs to your doctor.

Does inositol really work?

Studies on myo-inositol and D-chiro-inositol show modest effects on insulin sensitivity, cycle regularity, and certain hormonal parameters in some patients. The level of evidence is limited (often small, short-term studies). It is not a substitute for medical treatment. If you are considering taking it, discuss it with your doctor — particularly in case of pregnancy or current treatment.

What treatment for getting pregnant with PCOS?

Letrozole is the first-line treatment recommended for ovulation induction in PCOS, according to the Monash 2023 guideline. In the landmark Legro et al. 2014 RCT (NEJM), letrozole achieved a live birth rate of 27.5% per cycle compared with 19.1% for clomiphene in women with PCOS. The approach depends on many factors (ovulation presence and quality, partner parameters, age, duration of attempts). A complete fertility workup guides the choice. A gynaecologist or fertility specialist should be consulted once pregnancy planning is actively underway.

Can several treatments be combined?

Yes, often. PCOS is a multi-symptom syndrome and management is frequently multi-modal: a contraceptive for cycles and skin, metformin for the metabolic dimension, a topical for acne, and lifestyle support. Each combination must be evaluated and monitored by your doctor to avoid interactions and redundancies.
