CLIMARA PRO (estradiol)

Estrogen Receptor Agonists
Women's Health Approved 2003-11-21

Climara Pro is a combination hormone therapy used for women with a uterus to manage moderate to severe hot flashes and night sweats associated with menopause. It also helps patients at significant risk for postmenopausal osteoporosis by helping to prevent bone loss. This medication is typically prescribed when hormonal support is needed to address the physical symptoms of menopause or to protect bone health in high-risk individuals.

How CLIMARA PRO Works

The medication works by binding to nuclear receptors in various tissues to replace estradiol, the primary estrogen that naturally declines after menopause. This process helps lower elevated levels of pituitary hormones, while the included progestin works to counteract the proliferative effects that estrogen has on the lining of the uterus.
