What is bazedoxifene and conjugated estrogens?

Bazedoxifene blocks estrogen from reaching certain cells in the uterine lining, to protect against overgrowth of uterine tissue.

Estrogen is a female sex hormone produced by the ovaries. Conjugated estrogens are a mixture of estrogen hormones.

Bazedoxifene and conjugated estrogens is a combination medicine used short-term in women after menopause to treat moderate to severe hot flashes, and to prevent osteoporosis. This medicine is used in women who have NOT had a hysterectomy (uterus removed).

Conjugated estrogens should not be used to prevent heart disease, strokes, or dementia, because this medicine may actually increase your risk of developing these conditions.
