The short explanation
There is no single treatment for PCOS. Treatment is aimed at a specific goal — regulating cycles and protecting the lining of the womb, reducing acne or unwanted hair, improving how the body handles blood sugar, or helping you ovulate in order to conceive — and different tablets do different ones of those. The most useful question you can ask is which goal yours is for.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- A combined hormonal contraceptive is commonly used to make bleeding regular and to help acne and unwanted hair. It does not treat the underlying condition and it does not help you conceive; while you take it, you are also using contraception.
- Metformin is aimed at how the body handles insulin and glucose. It is judged over months rather than weeks, and it is not a weight-loss drug even though weight sometimes changes on it.
- Anti-androgen medicines used for hair and skin require reliable contraception alongside them, because they can harm a developing pregnancy. That is not a footnote — it is the first thing to establish before starting one.
- Cycles that go many months without a bleed can leave the lining of the womb thickened over time, and one reason a clinician induces regular bleeding is to prevent that. Asking whether that is the reason tells you why the prescription matters.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you what your tablet is, what it is for or whether it suits you. Only the clinician who prescribed it can, and she is the person to ask.
- Nothing here is a reason to stop or change a medicine. Stopping a contraceptive that is also treating something else has consequences in both directions.
- This explanation was written by AskHer's editorial team from the guidance listed under Sources. A clinician registered in India has not signed this version off yet — that is why no clinical reviewer is named at the foot of this page, and it is why nothing here is a diagnosis.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- What is this tablet aimed at — my cycles, my skin, my blood sugar, or fertility?
- How will we know whether it is working, and by when?
- What are the common side effects, and which ones should make me contact you?
- Do I need contraception alongside this?
- What happens when I stop it — do the symptoms come back?
When to seek help

Did this answer your question?
Whatever you choose is filed against this version of the answer, never against you, and it is never shown as a count.
“Explain more simply” asks you which part was hard to follow, so the author knows what to rewrite. “My question is different” opens a private follow-up with this answer attached.
Saving, following up and reporting are all private. Nothing you do on this page is visible to other readers or to the doctor who wrote it, unless you ask a question.
