If you have been diagnosed with PCOS (Polycystic Ovary Syndrome), you are not alone. About 1 in 5 Indian women of reproductive age has PCOS, according to studies published in Indian medical journals. You may also hear it called PCOD (Polycystic Ovarian Disease) — both names refer to the same condition. Your doctor may have prescribed medicines that seem confusing at first. This guide explains the most common PCOS medicines used in India, why they are prescribed, and what you should watch out for.
What Is PCOS? A Simple Explanation
PCOS is a hormonal condition where your body makes too many androgens (male-type hormones that women also have in small amounts). This hormonal imbalance can cause irregular periods, acne, excess hair growth on the face and body, weight gain, and difficulty getting pregnant.
Inside your ovaries, many small fluid-filled sacs (cysts) may form. Your eggs may not mature or release properly each month. PCOS also affects how your body uses insulin — the hormone that controls blood sugar. Many women with PCOS have insulin resistance, meaning their body needs more insulin to do the same job. This is why PCOS is closely linked to diabetes risk.
Common PCOS Medicines Prescribed in India
1. Metformin — Why a Diabetes Medicine for PCOS?
Metformin is one of the most commonly prescribed medicines for PCOS in India. You might wonder — "I don't have diabetes, so why am I taking a diabetes medicine?" The answer lies in insulin resistance.
Many women with PCOS have insulin resistance even if their blood sugar levels look normal. Their body is producing extra insulin to keep blood sugar in check. This extra insulin tells the ovaries to make more androgens, which worsens PCOS symptoms. Metformin helps your body use insulin more efficiently, which lowers insulin levels, which in turn reduces androgen production.
Metformin can help with:
- Making periods more regular
- Reducing androgen levels (which helps with acne and excess hair)
- Helping with weight management
- Improving ovulation (important if you are trying to conceive)
- Always take Metformin with food — never on an empty stomach
- Start with a low dose and increase slowly (your doctor should do this)
- Ask your doctor about Metformin SR/XR (extended release) — this version is much gentler on the stomach
- Give it 2-3 weeks — stomach side effects usually improve with time
2. Birth Control Pills (Oral Contraceptive Pills)
If you are not trying to get pregnant, your doctor may prescribe birth control pills. This can feel confusing — "Why contraceptive pills when my problem is PCOS?" These pills contain two hormones (estrogen and progestin) that help in several ways:
- They regulate your periods and make them predictable
- They reduce androgen levels, which improves acne and excess hair growth
- They protect the lining of your uterus — irregular periods can cause the uterine lining to build up too much, which increases the risk of problems later
Common brands prescribed in India include pills containing ethinyl estradiol with drospirenone or cyproterone acetate. Your doctor will choose the one that suits your specific symptoms.
3. Spironolactone — For Excess Hair and Acne
Spironolactone is actually a medicine originally used for blood pressure and fluid retention. But it also blocks the effect of androgens on your skin and hair follicles. Doctors prescribe it for PCOS when acne and excess facial/body hair (hirsutism) are major concerns.
Important things to know about Spironolactone:
- It takes 3-6 months to see results for hair and acne — be patient
- You must not get pregnant while taking it — it can affect a developing baby. It is usually prescribed along with birth control pills
- You may urinate more often, especially in the first few days
- Your doctor may check your potassium levels periodically
Why Doctors Prescribe Different Combinations
PCOS affects every woman differently. Some women mainly struggle with irregular periods. Others have severe acne and facial hair. Some are trying to get pregnant. Some have insulin resistance and weight gain as their biggest concern. Your doctor will choose a combination of medicines based on your specific symptoms and goals:
- Irregular periods + insulin resistance: Metformin + birth control pills
- Severe acne and hirsutism: Birth control pills + Spironolactone
- Trying to conceive: Metformin + ovulation-inducing medicines (like Letrozole or Clomiphene)
- Weight gain + insulin resistance: Metformin + lifestyle changes
If your treatment does not seem to be working after 3-6 months, talk to your doctor. They may need to adjust the combination or doses.
Side Effects to Watch For
All medicines can have side effects. Here are the important ones to be aware of:
- Metformin: Stomach upset, nausea, diarrhoea (usually improves). Rarely, vitamin B12 deficiency with long-term use — ask your doctor about checking B12 levels yearly
- Birth control pills: Nausea, breast tenderness, mood changes, headaches. Rare but serious: blood clots (tell your doctor immediately if you have sudden leg pain or chest pain)
- Spironolactone: Frequent urination, dizziness, irregular periods (when not taken with birth control pills), high potassium levels
Lifestyle Changes That Help Alongside Medicines
Medicines work much better when combined with lifestyle changes. Research from ICMR and international guidelines consistently shows that even a 5-10% weight loss can significantly improve PCOS symptoms.
- Regular exercise: 30 minutes of brisk walking, cycling, or swimming most days of the week. Exercise improves insulin sensitivity directly
- Reduce refined carbs and sugar: Choose whole grains (brown rice, whole wheat roti) over white rice and maida. Cut down on sweets, sugary drinks, and packaged snacks
- Eat more protein and fibre: Dal, eggs, paneer, vegetables, and salads help you feel full and keep blood sugar stable
- Sleep well: Poor sleep worsens insulin resistance. Aim for 7-8 hours
- Manage stress: Chronic stress raises cortisol, which worsens hormonal imbalance
PCOS and Diabetes Risk — Get HbA1c Checked Yearly
Women with PCOS are 2-4 times more likely to develop Type 2 diabetes compared to women without PCOS. This risk is even higher if you are overweight, have a family history of diabetes, or are over 30. The PCOS Society of India and the Endocrine Society recommend that all women with PCOS get their blood sugar checked regularly.
Ask your doctor for an HbA1c test (also called glycated haemoglobin) at least once a year. This test shows your average blood sugar over the past 3 months and can detect pre-diabetes early — before fasting sugar levels become abnormal.
When to See Your Doctor Again
Do not just take your medicines and wait for your next scheduled appointment. See your doctor sooner if:
- Your periods have not become more regular after 3-6 months of treatment
- You are having side effects that are hard to tolerate
- You are planning to get pregnant — your medicines will need to change
- You notice sudden weight gain, increased thirst, or frequent urination (signs of blood sugar problems)
- You feel very low, anxious, or depressed — PCOS can affect mental health, and your doctor can help
