Although I am not on HRT apart from Vagifem I have found this discussion interesting to follow. It very much depends on the individual GP. I have seen 2 female GPs over the last few years, one is happy for me to use Vagefem as much and as long as I need to but the other one, who I saw when 'my' GP was away, voiced concern about how much Oestrogen I was being given when I wanted to try Oestrogel.
(I should add that 'my' GP let me try Oestrogel with no problem but I didn't continue with it as it was not helpful). I just used that example to show how different 2 GPs in the same practice can be. One doing things by the book and another using her common sense.
