Thanks, I thought it was the higher norethisterone also! Yes the flushes and burning feeling stopped nearly immediately after removing the patch. Can you recommend other hrt options? My GP has limited knowledge of hrt and my appt with meno clinic is not until another two months. I tried Femoston conti 1/5 for one week but the period pain side effect was so unbearable I had to stop. My gp’s first choice was the Estalis conti patch. Thanks!
