What are conjugated estrogens (Cenestin, Enjuvia, Premarin)?
Estrogen is a female sex hormone produced by the ovaries. Estrogen is necessary for many processes in the body.
Conjugated estrogens are 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. Conjugated estrogens are sometimes used as part of cancer treatment in women and men.
Conjugated estrogens may also be used for other purposes not listed in this medication guide.

Do not use this medication if you have any of the following conditions: a history of heart attack, stroke, or blood clot (especially in your lung or your lower body), liver disease, abnormal vaginal bleeding, or a hormone-related cancer such as breast or uterine cancer.
Long-term treatment with conjugated estrogens may increase your risk of breast cancer, heart attack, or stroke. Talk with your doctor about your individual risks before using conjugated estrogens long term, especially if you smoke or are overweight. Your doctor should check your progress on a regular basis (every 3 to 6 months) to determine whether you should continue this treatment.
Have regular physical exams and self-examine your breasts for lumps on a monthly basis while using conjugated estrogens.
Conjugated estrogens should not be used to prevent heart disease or dementia, because this medication may actually increase your risk of developing these conditions.
