I am currently using the vivelle dot 0.025 but my insurance company will no longer cover it due to my age (71). My Dr. wants to put me on the minivelle. I have been on the vivelle patch for at least 15 years, and want to continue since it is working wonderfully for me, but have read MANY negative reviews about minivelle. And also read there were no clinical trials with the minivelle. Please help me out. Many thanks.
