Dr Currie posted this recently in another thread which I found very helpful, particularly to those of us who have to always fight for the correct dosage to ease symptoms. Although I can't get down to five pessaries a week but still need seven, I am reassured by her post and just to add my surgery has no problem prescribing Vagifem and Estriol daily.
"Vaginal estrogen is minimally absorbed, but we do not know the effects of using more than one preparation at a time, or using higher than licensed doses. As with HRT doses, if a licensed dose is not fully effective, then a different type could be considered but also the underlying problem may not be purely hormone related and review would be indicated.
The BMS consensus statement does not recommend adding preparations together--see
https://thebms.org.uk/wp-content/uploads/2024/04/09-BMS-ConsensusStatement-Urogenital-atrophy-MARCH2024-A.pdfThe dose increase for vaginal estrogen tablet as mentioned is reasonable because of the following--
Many years ago, we had a preparation Vagifem 25mcg--every night for 2 weeks then twice weekly. When it was taken off the market, we then used the lower dose Vagifem 10mcg (Vagirux is the same)--nightly for 2 weeks then twice weekly. So the maintenance dose of Vagifem 25 provided 50mcg of estradiol over a week, for which there was no concern about significant circulating absorption affecting the womb lining. Therefore, if needed, this can be achieved by using Vagifem 10 of Vagirux up to 5 times weekly. For many, twice weekly is enough and can be continued long term, for others using it 3 to 4 times weekly or maximum 5 times weekly works better.
If vulval and vaginal treatment needed, some find using the large volume estriol cream 0.01% applying half with a finger to the vulva and remainder into the vagina can be useful. However, other vulval conditions and sensitivity may need to be considered.
I hope that this is helpful."
