Your doctor is wrong and the advice is out of date, don't stop your daily treatment and give her/him some facts.
A quote from Dr Currie last year stated "The 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 haven't been confronted in a while about my daily Vagifem dose, plus Estriol cream but when I have been I always say I am not on systemic HRT and a box of Vagifem is equivalent to one systemic HRT tablet a year. I also mention if I leave out a dose by the following afternoon my symptoms will start to return. I have stopped many a confrontation by giving the facts of a very harmless but effective treatment.
