Last month, my physician prescribed Prometrium in addition to the Vivelle Dot. I had my ovaries removed almost a year ago and had been on just Premarin but was feeling horrible. With the Prometrium and patch, I felt much better while on them. The cycle for 12 days came to an end, and five days later, I hit rock bottom. Why cyclic in surgical induced menopause? Also, my insurance co. is now denying Prometrium and wants medroxyprogesterone used instead. Any answers?
