My D.O. just prescribed Medroxyprogesterone at my request; I had been on this before for PCOS, but I don't think it was prescribed to me in the correct way as I remember. The prescription is written to take 1 tablet(10mg) by mouth once daily. I don't think I am to take this every day for 30 days, so could you tell me what the correct dosage is for this problem and when do I begin taking it? Seems to me that I took it after I had a period for a period of 5 -10 days, I just can't remember. Thank you.
