Hi 2cats
I'm surprised that they have only prescribed one, and wonder what the basis is for this? The reason I ask is that there is no comparable oral combi HRT which has levonorgestrel in it (the progestogen in Norgeston), so how they can calculate the safe dose without this? There is (or rather was, as far as I can make out) a cyclical oral HRT called Cyclo-progynova which had norgestrel as the progestogen, but that is different in structure to levonorgestrel so not comparable.
In other cases the dose for HRT compared with mini pill might be double or even 3 x as is the case for norethisterone as a mini pill, marketed as Noriday. Noriday is 350 mcg norethisterone but for HRT the dose for peri is 1 mg ( 1000 mcg) ie 3 tablets. For low dose oral oestrogen (1mg) the norethisterone dose is given as 0.5 mg ( ie 500 mcg) so even then one mini pill of Noriday may not be enough.
Personally I would not want to use this as there is no information about it and it is not on the list of progestogens recommended by British Menopause Society even off-licence. If the nurse has research information to back up that prescription and is prepared to monitor you for this use, then perhpas you could give it a go, but I would suggest that one is definitely not enough and at least 2 as sheila suggests. Perhaps go for an alternative?
