Taking Norethindrone and Metformin at the same time, not for pregnancy
Hi there, I hope someone can please help me 🙂
I am 41 years old and have PCOS, uterine fibroids, and menorrhagia (never-ending period – I had it every day for about 3 months straight before I was prescribed the medication), so my gynecologist prescribed 15 mg/daily Norethindrone (Ajestin). I have been taking this for a couple of months now with no problems (except for forgetting one day, and then having to deal with several days of bleeding).
Also, I am pre-diabetic. Last week, my GP prescribed a starting dose of Metformin (500 mg twice a day) to help regulate my blood sugar. She was aware of my Norethindrone prescription, though she didn’t ask me for details of why it was prescribed.
However, in the notes that came with the Metformin, it says that “Metformin may make menstrual cycles more regular and increase fertility.” How is this going to react with Norethindrone? My GYN said that Norethindrone makes my body believe it’s in a different part of my cycle so that it won’t bleed. But will the Metformin make me bleed again? I’m really nervous about this, so I haven’t begun taking it yet. (I am not interested in getting pregnant)
