VAGINAL DRYNESS OVERVIEW
Vaginal dryness, also known as atrophic vaginitis, is a common condition in postmenopausal women. This condition is also common in women who have had both ovaries removed at the time of hysterectomy.
Some women have uncomfortable symptoms of vaginal dryness, such as pain with sex, burning vaginal discomfort or itching, or abnormal vaginal discharge, while others have no symptoms at all.
Fortunately, there are several effective treatments for vaginal dryness. If you think you have vaginal dryness, talk to your healthcare provider about which treatment is right for you. (See "Clinical manifestations and diagnosis of vaginal atrophy".)
VAGINAL DRYNESS CAUSES
Estrogen helps to keep the vagina moist and to maintain thickness of the vaginal lining. Vaginal dryness occurs when the ovaries produce a decreased amount of estrogen. This can occur at certain times in a woman's life, and may be permanent or temporary. Times when less estrogen is made include:
- At the time of menopause.
- After surgical removal of the ovaries, chemotherapy, or radiation therapy of the pelvis for cancer.
- After having a baby, particularly if you breastfeed.
- While using certain medications, such as danazol, medroxyprogesterone (Provera® or DepoProvera®), leuprolide (Lupron®), or nafarelin. When these medications are stopped, estrogen is produced normally again.
Women who smoke cigarettes have been shown to have an increased risk of an earlier menopause transition as compared to non-smokers. Therefore, atrophic vaginitis symptoms may appear at a younger age in this population.
VAGINAL DRYNESS TREATMENT
There are two treatment options for women with vaginal dryness: moisturizers/lubricants and vaginal estrogen. All vaginal dryness treatments work temporarily. The vaginal dryness will return when the treatment is stopped unless the ovaries make more estrogen.
Vaginal lubricants and moisturizers — Vaginal lubricants and moisturizers can be purchased without a prescription. These products do not contain any hormones and have virtually no side effects.
Lubricants are designed to reduce friction and discomfort from dryness during sexual intercourse. The lubricant is applied inside the vagina or on the penis just before having sex. Products designed as vaginal lubricants (eg, Astroglide®) are more effective than lubricants that are not designed for this purpose, such as petroleum jelly (Vaseline®).
Oil-based lubricants, such as petroleum jelly, baby oil, or mineral oil, may damage latex condoms and/or diaphragms and make them less effective in preventing pregnancy or sexually transmitted infections. Polyurethane condoms can be used with oil based products. Also, lubricants that are made with water or silicone can be used with latex condoms and diaphragms.
Natural lubricants, such as olive, avocado or peanut oil, are easily available products that may be used as a lubricant with sex. Again, natural oils are not recommended for use with latex condoms or diaphragms; the oil can damage the latex, potentially making it less effective in preventing pregnancy or sexually transmitted infections.
Vaginal moisturizes (eg, Replens®, Moist Again™, Vagisil®, K-Y® Silk-E®, and Feminease®) are formulated to allow water to be retained in the vaginal tissues. Moisturizers are applied into the vagina three times weekly to allow a continued moisturizing effect. These should not be used just before having sex, as they can be irritating.
Hand and body lotions should not be used to relieve vaginal dryness since they can be irritating to the vaginal tissues.
Vaginal estrogen — Vaginal estrogen is the most effective treatment option for women with vaginal dryness. Vaginal estrogen must be prescribed by a healthcare provider.
Very low doses of vaginal estrogen can be used when it is put into the vagina to treat vaginal dryness. A small amount of estrogen is absorbed into the bloodstream, but only about 100 times less than when using estrogen pills or tablets. As a result, there is a much lower risk of side effects, such as blood clots, breast cancer, and heart attack, compared with other estrogen-containing products (birth control pills, menopausal hormone therapy).
Several types of vaginal estrogen products are available:
- Estrogen cream (eg, Premarin®, Estrace® cream) is inserted into the vagina every day for two to three weeks, and then one or two times weekly. The cream can be difficult to measure accurately and insert into the vagina.
- The vaginal estrogen tablet (Vagifem®) is a small tablet that is inserted inside the vagina. The tablet is packaged in a disposable applicator. Vagifem is usually taken every day for two weeks and then twice weekly.
- The vaginal estrogen ring, called Estring®, is a flexible plastic ring that is worn inside the vagina all the time. It is replaced every three months by the woman or her healthcare provider. The ring does not need to be removed during sex or bathing. It cannot be felt by most women or their sexual partners. In women who have previously had a hysterectomy, the ring will sometimes fall out.
Estring® should not be confused with the estrogen replacement vaginal ring (Femring®), which releases a much higher dose of estrogen and is intended to be absorbed into the body to relieve hot flashes. (See "Patient information: Postmenopausal hormone therapy (Beyond the Basics)".)
How long can I use vaginal estrogen? — Vaginal estrogen is thought to be safe and can probably be used indefinitely, although there are no long-term studies confirming its safety.
Is vaginal estrogen safe for women with a history of breast cancer? — The safety of vaginal estrogen in women who have a past history of breast cancer is unclear. A small amount of estrogen can be absorbed from the vagina into the bloodstream. If you have a history of breast cancer, talk to your healthcare provider or your oncologist about the potential risks and benefits of vaginal estrogen.
Sexual activity — Vaginal estrogen improves vaginal dryness quickly, usually within a few weeks. You may continue to have sex as you treat vaginal dryness because sex itself can help to keep the vaginal tissues healthy. Sexual activity (including masturbation) may help the vaginal tissues by keeping them soft and stretchable and preventing the tissues from shrinking.
If sex continues to be painful despite treatment for vaginal dryness, talk to your healthcare provider. (See "Differential diagnosis of sexual pain in women".)
