Hi Sunnydays!
I am still here but only occassionally remember to look at posts so I'm really pleased I found yours so quickly!
There isn't any evidence that taking utrogestan vaginally has any harmful effects to the skin or vaginal walls, but the reason it isn't licensed here for that route is that there isn't enough research to show that it works for it to meet the standards of drug licencing. It's also curious to me that the recommended dose doesn't change if you have a smaller dose of oestrogen (as other progestins reduce with smaller oestrogen dosage) and having discussed this with my specialist doctor she said this was for the same reason: there isn't evidence yet of what a safe reduced dose would be. There's also no evidence yet on whether peri-menopausal women (like me) have enough of their own hormones for a lower dose to be safe. So, this means that she's relatively relaxed about me being flexible with route and dose, as long as i go back for annual scans.
At the moment things seem to be working really well for me, but it has taken some adjusting. I tried the 200mg cycle that I mentioned here, trying the vaginal and oral routes, and tried extending the cycle too. However, I found the fatigue side effects to be absolutely overwhelming in every variant and had to stop. I wondered if the problem was a culmulative build up with daily use, and after discussion with the specialist, I decided to try taking 100mg every other day. This is a conti regime, but it is obviously only just over half the recommended dose (I don't take a three day break). However, even here I found myself getting increasingly exhausted. My Dr was confused about this as it is such an extreme reaction, and I seemed to be tolerating it less well rather than getting used to it as I went on. She suggested I got tested for everything else just in case the fatigue wasn't drug related: I did this for a belt and braces approach though it was clear to me the fatigue coincided with utrogestan and stopped a few days after I stopped taking it. The obvious answer to me is that I am metabolising the drug slowly and it is producing culmulative effects even with a day off in between. My GP and the specialist both thought this was possible as women do metabolise drugs differently, and this could also be that i have some of my own hormones knocking about producing a progesterone overload. So: the upshot is that I am still taking it, and have been given permission to play around with the dosage as I go. At the moment I am having no issues at all taking it every two days for two doses, then at three days for one dose, then at two days for two doses, and so on. I've also reduced my oestrogen dose a little to 0.75mg (again, in discussion with the doctors) as I thought it might reduce the risks a little further, and am having no issues there either.
I haven't had any bleeds in four months which suggests that it is doing its job, though of course the extent of side effects and bleeds aren't a reliable indication of whether it is actually protecting the endometrium, and I'll only get a better sense of this when I go back for my scan in November. And the positive side is I feel absolutely fantastic: sex drive back, energy and all that - i feel like myself again, only with better skin!
I'm not in a relationship just now so I haven't had to negotiate the partner/drugs issue I initially wrote about, but as I've found a way to manage utrogestan orally I hope this won't be an issue. I'll keep you all posted though...
Does this help? How are you getting on?
All best wishes
