Hi Faf
from me too.
Well it is an old conundrum this utrogestan lark - but the truth is it will vary from woman to woman and where you are in menopause too.
I think a few weeks ago we discovered that the patient information leaflet is incorrect and someone contacted the manufacturers. The mistake may have been made when Besins took over from Ferring, former UK distributor.
The Summary of Product Characteristics is correct:
https://www.medicines.org.uk/emc/medicine/19895This is what it says:
Posology
In women receiving estrogen replacement therapy there is an increased risk of endometrial cancer which can be countered by progesterone administration. The recommended dose is 200 mg daily at bedtime, for twelve days in the last half of each therapeutic cycle (beginning on day 15 of the cycle and ending on day 26). Withdrawal bleeding may occur in the following week. Alternatively 100 mg can be given at bedtime from day 1 to day 25 of each therapeutic cycle, withdrawal bleeding being less with this treatment schedule.Your doctor is correct.
The translation of the french leaflet also says to use 200 mg vaginally if used this way (ie when side effects from oral use) but many women take less because of the "uterus first pass effect" ie goes straight to the uterus where it is needed, and research papers show that a lower dose can be effective in preventing endometrial hyperplasia.
Vaginal use is thought to have fewer side effects, but my view is that the vagina needs to be well plumped up and not atrophied, to minimise absorption in the rest of the body - but I have no evidence for this!
Personally, if you are starting with vaginal use I would take the full dose, to ensure it is effective and then maybe tweak the dose after a few months and see how your body reacts and how your bleeds are.
Sorry this is in haste as working tonight!
