endometrial hyperplasia, prophylaxis
"I take this med because I use vivelle estrogen patch and need progesterone every 3 months to prevent uterine lining buildup.

I take 200 intravaginally, every other day for 12 days - 6 doses total - every 3 months.  

At first dose, I was slammed with drowsiness, lower back pain, hot flashes at night, restless sleep and weakness in legs. I had cramps, but did not get a period. By the last dose, the side effects were better. but still it was no picnic.

It's a small price to pay however for being able to take vivelle dot and get estrogen, and as far as I understand, the easiest way to take progesterone as I don't want a uterine implant."
