Patient Education

Estrogen and Bazedoxifene


Estrogen and bazedoxifene tablets are used to treat hot flashes (sudden feelings of warmth, especially in the face, neck, and chest) in women who are experiencing menopause (stage of life when menstrual periods become less frequent and stop and women may experience other symptoms and body changes). Estrogen and bazedoxifene tablets are also used to prevent osteoporosis (condition in which the bones become thin and weak and break easily) in women who have undergone menopause. Estrogen is in a class of medications called hormones and bazedoxifene is in a class of medications called estrogen agonist–antagonists. Estrogen works by replacing estrogen that is normally produced by the body. Bazedoxifene is used to block the action of estrogen on the lining of the uterus, decreasing the risk of overgrowth that may lead to cancer.
