Menest

Menest is a prescription estrogen hormone replacement medication. It is approved for treating menopausal symptoms, reducing the symptoms of certain cancers, and treating hormonal deficiency in younger women whose ovaries do not produce enough estrogen. Menest comes in tablet form and is available in several strengths, ranging from 0.3 to 2.5 mg. Potential side effects of the drug include nausea, abdominal pain, and vaginal bleeding.

 

What Is Menest?

Menest® (esterified estrogens) is a prescription hormone replacement medication. Although it is most often used as a hormone replacement for menopausal women, it is approved for several different uses. Approved uses of Menest include:
 
  • Treating menopausal symptoms, such as hot flashes and vaginal dryness
  • Replacing hormones in younger women whose ovaries do not produce enough estrogen (or who have had their ovaries removed)
  • Reducing the symptoms of certain cancers (in both men and women) that have spread throughout the body.

How Does Menest Work?

Menest contains a mixture of different estrogens. These estrogens are derived from plant sources. Menest helps to relieve menopausal symptoms by replacing the estrogen that the ovaries no longer produce. Because estrogen helps to keep the bones strong, the decrease in estrogen during menopause causes a significant weakening of the bones, often resulting in osteoporosis. By providing estrogen, Menest can help prevent these menopause-related bone changes.
 
Very high doses of Menest can work to relieve the symptoms of certain cancers, including breast and prostate cancer. For prostate cancer, high doses of the estrogens in Menest work by suppressing testosterone and other male hormones that "feed" prostate cancer. It is not entirely clear how high doses of Menest work for breast cancer, as estrogen usually stimulates breast cancer cell growth. Menest will not cure these types of cancers and should only be used to relieve symptoms when other treatments have failed to treat the cancer adequately.
