There are not many Drs. left that prescribe premerin and prempro anymore. One of the main reasons many ladies and Drs. have stopped using premrin and prempro is because its made from pregnant horses urine. There are so many other natural/vegtable HRTs now that Drs. can prescribe that they can stop producing premrin and prempro from horses.
I was looking up those specific HRTs last week on the net and also found websites on how the horses are treated that they get the HRTS from. Thousands of foals are born every year and are sent to the slaughter houses for dog food. The mares are kept in small stalls their whole lives and are unable to move around. Its very sad.
Since the reports came out last year about HRTs alot of women have gone off them completely. Women are using soy as a substitute. Some are using natural progesterone. Some are going cold turkey and not using anything. I'm not one of those women. My symtoms are too great for me to go without estrogen. I take estriodial without any progesterone.
I believe that prempro is estrogen with progestin. You can get a natural estogen - estriol creme with progesterone at a compound pharmacy with a RX from your Dr. It is something to talk to your Dr. about.
Hope I didn't give you more information than you wanted to know.....
