Unfortunately there aren't many alternatives available licensed for use with HRT.
If you look here there is only MPA (medroxyprogesterone acetate) available as Provera and Climanor.
www.menopausematters.co.uk/to_progestogens.php It is less androgenic than the norethisterone types.
However norethisterone can also be used - but not recommended if you are progesterone intolerant - but good for heavy bleeding. A knowledgeable GP, and presumably all gynaes would prescribe this.
In terms of progesterone - when I first started HRT in 2007 and for the next 4 years I used Cyclogest which is a progesterone (ie the real stuff like utrogestan) waxy pessary which can also be used a suppository. This isn't licensed for HRT though, but my GP was keen on it. I eventually found the dose too high ( 2 x 200 mg).
There is also Crinone vaginal gel but not sure even if this is still available and I never hear of it being used - even by women reporting about their private gynaes on here.
Both of these (I think - but might be wrong) were available before Utrogestan which seem to be the favoured product now.
