    Premarin (Conjugated Estrogens) Dosage and Side Effects

    This medication is a female hormone. It is used by women to help reduce symptoms of menopause (such as hot flashes, vaginal dryness). These symptoms are caused by the body making less estrogen. If you are using this medication to treat symptoms only in and around the vagina, products applied directly inside the vagina should be considered before medications that are taken by mouth, absorbed through the skin, or injected. Certain estrogen products may also be used by women after menopause to prevent bone loss (osteoporosis). However, there are other medications (such as raloxifene, bisphosphonates including alendronate) that are also effective in preventing bone loss and may be safer. These medications should be considered for use before estrogen treatment. Certain estrogen products may also be used by men and women to treat cancers (certain types of prostate cancer, breast cancer that has spread to other parts of the body) and by women who are not able to produce enough estrogen (for example, due to hypogonadism, primary ovarian failure). Talk to your physician about the benefit of using Premarin (Conjugated Estrogens), as well as discuss the risk associated with it. Your doctor will determine which treatment is best for the symptoms you are experiencing.
