PCOS treatment options

PCOS treatment depends on the symptoms or health risks you want help with, your overall health and your pregnancy plans. A treatment that helps unwanted hair may do little for the concerns behind a blood glucose check. There is no cure, but symptoms can be treated.

PCOS is now called polyendocrine metabolic ovarian syndrome, or PMOS. Both names refer to the same condition; this article uses PCOS to match the name you may already know.

Begin with the aim of treatment

Ask what each proposed treatment is meant to help with. The Office on Women’s Health describes plans based on symptoms, future pregnancy wishes and longer-term risks such as diabetes and heart disease. WHO recommends making these decisions with your clinician, taking your values and preferences into account.

Some treatments are prescribed off-label, meaning their use for PCOS is outside the specific approval for that medicine. This can still be based on evidence. The guideline asks clinicians to explain the evidence, concerns and side effects, and NICHD notes this is common in US PCOS care.

Hormonal options for bleeding and hair growth

The combined oral contraceptive pill can help irregular cycles and excess hair growth, and may also improve acne. Discuss your health risks and possible side effects with your clinician to decide whether it is suitable. The international guideline does not identify a single pill preparation for everyone with PCOS.

Protecting the womb lining is another treatment goal when periods are infrequent. The guideline includes cycle regulation and progestogen therapy among preventive options. Progestogen-only pills may be considered for lining protection, although PCOS-specific evidence is limited; the NHS also lists the hormonal IUS for irregular periods.

Ask your prescriber what the proposed method would do for you. If pregnancy is something you want now or later, bring that into the discussion before choosing a treatment. Some PCOS treatments prevent pregnancy or can harm a developing fetus.

What metformin is used for

Metformin mainly targets metabolic features of PCOS, including how the body handles insulin and blood glucose. It may also help cycles or ovulation for some people, but usually has little effect on acne or excess facial and body hair. Your doctor can advise whether it fits the problem being treated.

Digestive side effects can occur. Metformin is also linked to low vitamin B12, particularly in people with additional risk factors. The guideline says monitoring may be considered in these cases. Ask which side effects to report and whether any checks are needed for you.

Anti-androgens and hair treatment

Anti-androgen medicines reduce the effects of androgen hormones. They may help excess hair, acne or scalp hair loss, but evidence for scalp hair treatment specifically in PCOS is limited. The NHS lists spironolactone among options for reducing hair growth.

The international guideline considers anti-androgens when other approaches have not helped enough. Effective contraception is needed whenever pregnancy is possible because these medicines can harm fetal development. Ask the prescriber to explain the contraception plan and what to do if pregnancy becomes possible.

What the evidence says about inositol

The guideline includes inositol as a supplement you may choose to consider. There may be improvements in some metabolic measures, but clinical benefits for ovulation, hair growth and weight are limited. Evidence is not strong enough to recommend a particular type or combination.

For infertility, the guideline is more cautious: inositol remains experimental because benefits and risks are too uncertain to recommend it as a fertility therapy. Supplement quality and regulation can also differ from medicines. Ask your pharmacist or doctor before adding a product to your care plan.

Medicines for higher weight

The guideline allows consideration of weight-management medicines, including GLP-1 receptor agonists such as semaglutide or liraglutide, alongside lifestyle support under general prescribing guidance. They are not automatic treatment for everyone with PCOS.

Discuss side effects and the possibility of long-term use with your prescriber, including weight regain after the medicine is stopped. Effective contraception is advised when pregnancy is possible because pregnancy safety data are lacking. Ask your prescriber how these issues apply to the particular medicine being considered.

Advice has changed recently: the MHRA strengthened warnings about acute pancreatitis with these medicines in January 2026.

Seek urgent medical help now through your GP or NHS 111 (UK), or your doctor or an urgent medical service (US or elsewhere), if you use a GLP-1 medicine and develop severe belly pain that persists, particularly if it spreads to your back, with or without feeling sick or vomiting. Ask the clinician assessing you what to do about your medicine.

Reviewing the plan with your clinician

Book a GP appointment in the UK, or see your doctor in the US or elsewhere, if symptoms still affect daily life or your treatment priorities have changed. Ask which benefit to look for, when to review progress and who to contact about side effects.

Discuss any changes to prescribed treatment with your clinician. If you are planning pregnancy or are pregnant, do not stop a prescribed medicine without talking to your doctor; arrange a medicines review.
