Metformin (Glucophage) for Polycystic Ovary Syndrome
How It Works
Why It Is Used
Metformin is a diabetes medicine sometimes used for lowering insulin and blood sugar levels in women with polycystic ovary syndrome (PCOS). This helps regulate menstrual cycles, start ovulation, and lower the risk of miscarriage in women with PCOS. Long-term use also lowers diabetes and heart disease risk related to high insulin levels.1
How Well It Works
Metformin lowers insulin, androgen, and cholesterol levels. It also improves metabolism in women who are insulin-resistant.

What To Think About
Blood levels of vitamin B12 can decrease in women who take this medicine, but the lower level usually does not cause health problems. Doctors do recommend that women who take metformin also take a daily multiple-vitamin supplement.
You may need to stop taking metformin temporarily before major surgery or other medical procedures, such as X-rays that use contrast dyes. Talk to your doctor about this before your surgery or procedure.
The effect of metformin may be increased if you also take cimetidine (Tagamet). Before you take metformin, talk with your doctor about any other medicines you are taking.
Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
Advice for women
If you are pregnant, breast-feeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
