hi found this on this site<link> its about all i can find doing research on it. there’s more on site just copy into google to the www. to open and read. our data show that a combination of metformin and contraceptive pill may be more effective in suppressing the hyperandrogenemia of obese and non-obese pcos patients than metformin alone and may reduce insulin levels more than contraceptive pill alone. hence combined treatment may become a more effective therapeutic option for pcos. so what its saying isit would not harm the bc pills is this for weight loss? hope it helps you. good luck
will my birth control pill still be effective if i take metformin to lose weight? . my obgyn wanted me to look into birth control pills and consider my options. i do not want a birth control pill that will make me gain weight or make it difficult for me to lose weight which is why she also suggested adding metformin to a birth control plan. i'm curious if the metformin is actually effective in assisting in weight loss and if it would in some way cancel out the effectiveness of any birth control i take. i want to keep losing weight but do not want to get pregnant either.
