Q: How much Metformin is necessary to treat polycystic ovarian syndrome (PCOS) during pregnancy? How much should I take to treat diabetes? What should my dosage be?

A: Metformin is used to help regulate blood sugar and restore your body's ability to use insulin properly. The exact dose must be suggested by your doctor. Recommended dosages for metformin in patients with polcystic ovarian syndrome (PCOS) are usually 500 mg three times daily or 850 mg twice daily. The maximum recommended dose of metformin (usually in diabetic patients) is 2550 mg per day (3 x 850 mg pills).
