Estrogen is a female sex hormone produced by the ovaries. Estrogen is necessary for many processes in the body.

Enjuvia is a mixture of estrogen hormones used to treat symptoms of menopause such as hot flashes, and vaginal dryness, burning, and irritation. Other uses include prevention of osteoporosis in postmenopausal women, and replacement of estrogen in women with ovarian failure or other conditions that cause a lack of natural estrogen in the body. Enjuvia is sometimes used as part of cancer treatment in women and men.

Enjuvia should not be used to prevent heart disease or dementia, because this medication may actually increase your risk of developing these conditions.

Enjuvia may also be used for other purposes not listed in this medication guide.

This medication can cause birth defects in an unborn baby. Do not use Enjuvia if you are pregnant.

Long-term treatment with Enjuvia may increase your risk of breast cancer, heart attack, or stroke.
