As a woman approaches menopause, the production of estrogen and progesterone fluctuates and then decreases significantly. Symptoms such as hot flashes often result from the changing hormone levels. After a woman's last menstrual period, when her ovaries make much less estrogen and progesterone, some symptoms of menopause might disappear, but others may continue.

To help relieve these symptoms, some women use hormones. This is called menopausal hormone therapy (MHT). This approach used to be called hormone replacement therapy or HRT. MHT describes several different hormone combinations available in a variety of forms and doses.

How is hormone therapy administered?

According to the American Medical Association, hormone therapy can be administered in a variety of methods, including the following:

  • Estrogen pills
    Estrogen pills can either be taken every day or for 25 days each month. Women who have had a hysterectomy can take estrogen alone, while those who have not may take a combination pill (estrogen and progestin).
  • Estrogen/progestin pills
    There are two methods—the continuous method and the cyclic method—for taking estrogen and progestin. In the continuous method, a pill that contains both estrogen and progestin is taken daily. Occasionally, irregular bleeding may occur.

    The cyclic method involves taking estrogen and progestin separately—with estrogen taken either every day or daily for 25 days of the month and progestin taken for 10 to 14 days of the month. This may cause monthly "withdrawal" bleeding.
  • Estrogen and estrogen/progestin skin patches
    Using this method, a patch is applied to the skin of the abdomen or buttocks for 3 or 7 days. The patch is then discarded and a new one is applied. The patch can be left on at all times, even while swimming or bathing, and either the estrogen, or estrogen/progestin combination is delivered through the skin into the bloodstream. Progestin can be taken in a pill form with the patch. The patches may cause monthly bleeding.
  • Estrogen cream
    Estrogen cream is inserted into the vagina or used locally around the vulva to help with vaginal dryness and urinary problems.
  • Raloxifene
    Raloxifene is an estrogen-like drug (sometimes called "designer estrogen") that is part of a new class of drugs called selective estrogen receptor modulators (SERMs).For women who are appropriate candidates, this type of therapy can often be customized to provide the most benefits with the least side effects. It is important for women to talk with their health care providers about any discomfort or menstrual symptoms experienced with hormone treatment, as treatment approaches and dosages can be adjusted.
