Hi Everyone , I've been on Elleste Duet 2mg tablets for 6 months , they are out of stock everywhere . The substitute prescription my doctor has sent to my chemist is for Femoston-conti 1mg/5mg . The Elleste say they contain 16 2mg estradiol tablets and 12 2mg estradiol & 1mg norethisterone tablets . While the Femoston-conti contain 1mg estradiol and 5mgs dydrogesterone each . Im worried they are not comparable with less oestrogen and way more progesterone in the alternative I've been given . i will query this with my doctor on monday but wondered if anyone else had been given a substitute for Elleste Duet with a better comparable hormone ratio :(
