Side Effects of Premarin

Premarin is 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.

Premarin works by replacing natural estrogens in a woman who can no longer produce enough estrogen. It works for advanced prostate cancer by antagonizing male hormones.
