I just thought it might be useful to someone out there to hear my experience with Provera. I'd been on Utrogestan, 100mg vaginally for 10 days every month alongside Evorel 100 patches, for at least a year. But always struggled to get thru the full 10 days - I think 8 was the most I ever managed, I found the insomnia and gradually worsening depression too much to cope with. Needless to say my GP was initially sceptical about me trying anything else, but I insisted I wanted to try Provera as I'd heard good things about it. After doing a bit of research she agreed, and I'm now on Day 11 of oral Provera (10mg) with no sleep disturbance, no additional depression or any other side effects. Aiming for 14 days but we'll see. Just goes to show that body-identical isn't always best - Provera is synthentic, but a gynaecologist told me it was the gentlest of the progestins she'd recommend (by which she meant the most 'female'). Many women seem to have terrible struggles with Utrogestan but stick with it because it's body identical so it must be best....not necessarily so. Mind you, I haven't been thru the withdrawal bit yet, but synthetic progestins have a longer half-life than Utrogestan so that should make withdrawal easier, as it takes longer to leave the body. Am I right Hurdity, or have I completely misunderstood the science?
