Hi there donnacrichton
There are four main patches that can be prescribed at 50 mcg ( listed under HRT preparations) - Estraderm, Estradot, Femseven and Evorel. Of these Estraderm is the largest - at 4 x the size of Estradot, with Femseven and Evorel being about 3 x the size. Estraderm and Femseven contain the same total amount of estradiol, with Evorel twice as much and Estradot half as much. However they are all designed to deliver the same amount of estradiol through the skin ie 50 mcg per 24 hours. Whether they do or not will depend to some extent on your own skin! However if you apply it to the same part of your body hopefully all will be OK. There are differences in the composition of the adhesive:
Estradot:Adhesive matrix:
− acrylic adhesive,
− silicone adhesive,
− oleyl alcohol,
− dipropylene glycol,
− povidone (E1201).
EstradermAcrylate
Methacrylate
isopropyl palmitate
polyethylene terephthalate
ethylenevinylacetate copolymer,
Not being a chemist I am none the wiser
- but hopefully as Tempest says - this one is suitable - it is very big though!
Tempest - you can post anywhere - as we all can!!
