Question: how long do you take metformin for pcos?
Answer: A start dose of 500 mg daily during the main meal of the day for 1–2 weeks can lessen the side effects and allow tolerance to develop. A weekly or biweekly increase by 500 mg a day can then be pursued as required until a maximum dose of 2500–2550 mg/day is reached depending on the clinical benefit and side effects.
