Discuss the risks and benefits of hormone treatment with your doctor. Estrogens should not be used to prevent heart disease or dementia.Estrogens can increase the risk of cancer of the uterus (endometrial cancer). The bazedoxifene in this product may help decrease this risk. Tell your doctor right away if you have any unusual vaginal bleeding.In postmenopausal women, estrogens, taken with or without a progestin, increase the risk of cancer of the breast/ovaries, stroke, dementia, and serious blood clots. When used along with a progestin, estrogens also increase the risk of heart disease (such as heart attacks).The risk for serious side effects may depend on the dose of estrogen and the length of time it is used. This medication should be used at the lowest effective dose and for the shortest amount of time. Discuss the use of this medication with your doctor and check with him/her regularly (for example, every 3 to 6 months) to see if you still need to take this medication. If you will be taking this medication long-term, you should have regular complete physical exams (for example, once a year) as directed by your doctor. See also Notes section. USES: This medication is a combination product containing conjugated estrogens and bazedoxifene (an estrogen agonist/antagonist). It is used by women with a uterus to help reduce symptoms of menopause (such as hot flashes, vaginal dryness) and to prevent bone loss (osteoporosis) after menopause. Conjugated estrogens are female hormones which help to decrease menopausal symptoms caused by the body making less estrogen. Bazedoxifene is not a hormone, but works by acting like estrogen (as a selective estrogen receptor modulator or SERM) in some parts of the body. The bazedoxifene in this medication helps to preserve bone mass and reduces the risk of cancer of the uterus which can be caused by using estrogen.If you are using this medication to treat symptoms only in and around the vagina, consider using products applied directly inside the vagina instead of medications that are taken by mouth, absorbed through the skin, or injected.
