OTHER NAME(S): Estradiol-Norethindrone Acet Tablet
Estrogens, either used alone or with a progestin, have rarely caused very serious side effects. Discuss the risks and benefits of hormone treatment with your doctor. Estrogens and progestins should not be used to prevent heart disease or dementia.
In postmenopausal women, estrogen when used with a progestin can increase the risk of heart disease (such as heart attacks), stroke, serious blood clots in the lungs/legs, dementia, and cancer of the breast/ovaries.
The risk for serious side effects may depend on the dose of estrogen and the length of time it is used. Therefore, this medication should be used at the lowest effective dose and for the shortest amount of time. Discuss the use of this medication with your doctor regularly (for example, every 3 to 6 months) to see if you still need to use it. If you will be using this medication long-term, you should have regular complete physical exams (for example, once a year) as directed by your doctor. See also Notes section.Show More
This medication contains 2 female hormones: an estrogen (such as conjugated estrogen, estradiol) and a progestin (such as medroxyprogesterone, norethindrone, norgestimate). 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. The progestin in this medication helps to reduce the risk of cancer of the uterus which can be caused by using estrogen. Women who have had their uterus removed do not need the progestin and therefore should not use this combination medication.
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.
This medication 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/progestin treatment.
