This may be old news but I was pleasantly surprised when I went to get my prescription at walgreens filled. My doc had added progesterone, at my request, to my med list and she prescribed medroxyprogesterone. I called her and asked about switching to prometrium and she was fine with that but said "It's gonna be 10X what medroxyprogesterone costs which is why I didn't suggest it". She was right, the brand drug was going to cost $85 for the small size in a months supply, the medroxy was $9. The generic with my discount card is $45, about half as much as the band name one. I'm not sure how long generics have been available in the US but it's good news that the safer/less side effect prone med is now more reasonably priced..
