Has anyone else experienced this? I have been using 150 Evorel patches for eight months now. I have been using a high dose because I was clearly having trouble absorbing them from the beginning. My estrogen levels have dropped from 236 to 150 to 90 over the months. My baseline before hrt was 50. My symptoms have now all returned, plus some new ones. Groan. Don’t know what to try now as I don’t know if I might have the same problem with all transdermal methods. Keen to know if anyone had a similar experience and what they tried next.
