Hi warwick
I really don't know why your nurse has suggested taking this type of HRT - it is tablet HRT and also contains norethisterone as you said, which can cause side effects. It is quite a low dose of oestrogen ( 1 mg) and much lower than the other preparations you've had. Also as Taz says, at your age you don't want to be going back onto a tablet at all if you want to continue with HRT. Can't you see a doctor who will be more knowledgeable?
I am sure you have tried Utrogestan? If not why not change to a 50 mcg patch ( ie the same dose as Femseven) and take separate progesterone rather than change to a tablet which is going to cause more upset to the system?
Alternatively if you got on well with the Femseven then why not have a Mirena fitted which contains the same progestogen, but less of it gets into the system, and then carry on with a 50 mcg patch?
