Hi.. i am being dignosed having pcod and having abnormal menstruation. My ob prescribed only duphaston for every after 21 days of the cycle, twice a day for 5 days. But the sonologist suggested that I should take glucphage 500mg because my pco is very clear on the ultrasound. Im just confuse because glucophage 500mg is for patient with type 2 diabetis. What will I do? Do I need to stop the duphaston and start taking glucophage instead? Thank you.
