I'm in my 20s and my doctor is about to put me on Evista. I have severe endometriosis and she and an endometriosis specialist thought it might be a good idea since I cannot take any HRTs or birth control. I still have my uterus and ovaries. She said the medication would put me into menopause but I forgot to ask that if a condom broke would I need to get the morning after pill or would I be ok not to because of being on Evista.
You should not be taking Evista unless you are post-menopause, according to doctors.
"Evista® (raloxifene hydrochloride) is a prescription medication used to prevent and treat osteoporosis, as well as to prevent breast cancer. The drug should not be used during pregnancy or even in women who may become pregnant. It is important to remember that Evista is not approved for premenopausal women (including those who are pregnant).
Evista and Pregnancy Category X
The U.S. Food and Drug Administration (FDA) uses a category system to classify the possible risks to a fetus when a specific medicine is taken during pregnancy. Pregnancy Category X is given to medicines that show problems to the fetus in animal studies or in humans who have taken the medicine.
Evista is a selective estrogen receptor modulator (SERM), which means that it sometimes acts like estrogen and sometimes acts like an anti-estrogen. Since disruption of estrogen can cause problems during pregnancy, it would be expected that Evista would not be safe for use during this time. When Evista was given to pregnant rabbits, it increased the risk of miscarriages, defects, and brain or skull problems. Giving the drug to pregnant rats caused developmental delays and problems, as well as delayed labor and delivery. In addition, the offspring of rats that were given Evista during pregnancy had reduced fertility as adults."
