Hormone Replacement Therapy for Menopause
In the past, hormone replacement therapy (HRT) was widely recommended for the treatment of menopause and menopausal symptoms as well as in the prevention of osteoporosis and heart disease. A large study known as the Women's Health Initiative (WHI) shed new light on how HRT is viewed.
What Is Hormone Replacement Therapy?
Hormone replacement therapy is used to supplement the body with either estrogen alone or estrogen and progesterone in combination during and after menopause. Estrogen and progesterone are hormones that are produced by a woman's ovaries. When the ovaries no longer produce adequate amounts of these hormones (as in menopause), HRT can be given to supplement the body with adequate levels of estrogen and progesterone.
Why Does the Body Need Estrogen and Progesterone?
Estrogen and progesterone together thicken the lining of the uterus, preparing it for the possible implantation of a fertilized egg. Estrogen also influences how the body uses calcium, an important mineral in the building of bones, and helps maintain healthy levels of cholesterol in the blood. Estrogen also keeps the vagina healthy.
As menopause nears, the ovaries reduce most of their production of these hormones. Lowered or fluctuating estrogen levels may cause menopause symptoms such as hot flashes, and medical conditions such as osteoporosis. Hormone therapy helps to replenish the estrogen, relieving some of the symptoms of menopause and helping to prevent osteoporosis.
Why Is Progesterone Taken?
Progesterone is used along with estrogen in women who still have their uterus. In these women, if taken without progesterone, estrogen increases a woman's risk for cancer of the endometrium (the lining of the uterus). During a woman's reproductive years, endometrial cells are shed during menstruation. When the endometrium is no longer shed, estrogen can cause an overgrowth of cells in the uterus, a condition that can lead to cancer.
Progesterone reduces the risk of endometrial cancer by making the endometrium shed each month. As a result, women who take progesterone may have monthly bleeding. Monthly bleeding can be lessened and, in some cases, eliminated by taking progesterone and estrogen together continuously. Women who have had a hysterectomy (removal of the uterus through surgery) usually do not need to take progesterone.
What Are the Types of Hormone Replacement Therapy?
There are two main types of hormone replacement therapy:
- Estrogen Therapy: Estrogen is taken alone. Doctors most often prescribe a low dose of estrogen to be taken as a pill or patch every day. Estrogen may also be prescribed as a cream. You should take the lowest dose of estrogen needed to relieve menopause symptoms and/or to prevent osteoporosis.
- Progesterone/Progestin-Estrogen Hormone Therapy: Also called combination therapy, this form of HRT combines doses of estrogen and progesterone (progestin is a synthetic form of progesterone). Estrogen and a lower dose of progesterone also may be given continuously to prevent the regular, monthly bleeding can occur when combination HRT is used. The current recommendation is to take the lowest dose of hormone therapy for the shortest time consistent with the reason the woman is taking the therapy. Like all prescription medications, HRT should be re-evaluated each year.

VIVELLE-DOT (estradiol transdermal system) IS AVAILABLE BY PRESCRPTION ONLY.
INDICATION
Vivelle-Dot is used after menopause to: reduce moderate to severe hot flashes; treat moderate to severe dryness, itching and burning in or around the vagina; help reduce your chances of getting osteoporosis (thin weak bones); and treat certain conditions in which a young woman's ovaries do not produce enough estrogens naturally. Vivelle-Dot 0.025 mg/day is only used to prevent osteoporosis from menopause. If you use Vivelle-Dot only to treat your dryness, itching, and burning in and around your vagina or if you use Vivelle-Dot only to prevent osteoporosis from menopause, talk with your healthcare professional about whether a different treatment or medicine without estrogens might be better for you.
IMPORTANT SAFETY INFORMATION
Estrogens increase the chances of getting cancer of the uterus (womb). Report any unusual vaginal bleeding right away while you are taking estrogens. Vaginal bleeding after menopause may be a warning sign of cancer of the uterus (womb).
Do not use estrogens with or without progestins to prevent heart disease, heart attacks, or strokes. Using estrogens with or without progestins may increase your chances of getting heart attacks, strokes, breast cancer, and blood clots. Using estrogens with progestins may increase your risk of dementia (decline in memory and thinking skills).
Vivelle-Dot should not be used if you have unusual vaginal bleeding; currently have or have had certain cancers, including cancer of the breast or uterus; had a stroke or heart attack in the recent past (for example, in the past year); currently have or have had blood clots; currently have or have had liver problems; or think you may be, or know that you are, pregnant.
The most common side effects that may occur with Vivelle-Dot are headache, breast tenderness, and back pain.
You and your healthcare professional should talk regularly about whether you still need treatment with Vivelle-Dot.
You are encouraged to report negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.
