I'm having the exact same thing on being given Estradot instead of Evorel. Evorel controlled the VA brilliantly - half an Evorel 50 and I was fine. Day 3 on Estradot and cannot stay off the loo, even with 2 50"s on.
I asked for Evorel on repeat prescription and they put 'Estradiol patches'. Well they don't effing work. I put on 2 50 patches and I may as well have stuck on bits of sellotape. Going back to pharmacy tomorrow, hopefully they'll exchange it.
Thank Goodness I've still got some get left. Could hardly believe I searched on here and found someone who the exact same thing ha happened to. This forum is so helpful.
