People who experience menopausal symptoms, postmenopausal osteoporosis, or certain cancer symptoms may benefit from using Premarin® (conjugated estrogens). Premarin is a mixture of natural equine (horse) estrogens. It helps to relieve menopausal symptoms by replacing the estrogen that the ovaries no longer produce. Most people tolerate Premarin well; and even when side effects occur, they are usually minor and are easily treated by you or your healthcare provider. Some side effects of Premarin include vaginal bleeding, joint pain, and headaches.
