Estrace vaginal cream systemic absorption-Systemic absorption and sustained effects of vaginal estrogen creams.

Systemic absorption and sustained effects of two estrogen vaginal cream preparations Premarin and Estrace were measured in 29 postmenopausal women receiving daily applications. With both preparations, vaginal absorption of estrogens into the systemic circulation was rapid, efficient, and sustained. It is apparent that estrogen vaginal cream preparations, as widely used in clinical practice for their local effects on the vaginal mucosa, actually result in sustained high estrogen levels in the systemic circulation. The vaginal route shows promise when systemic estrogen therapy is indicated, but is dangerous when estrogen is contraindicated. All Rights Reserved.

The risk of any serious adverse effect is unlikely for most women using low doses of estrogens vaginally. Some authors note that even a small increase in systemic estradiol levels may have a detrimental effect on recurrence risk and that more data are needed before recommendations can be made regarding the use of vaginal estrogen among this population 16, Locating pain in breast cancer survivors experiencing dyspareunia: a randomized controlled trial.

  • I use a vaginal estrogen cream for vaginal dryness.

My doctor prescribed a low-dose vaginal estrogen cream, applied twice a week, for atrophic vaginitis. I've heard this dose is so low that it carries no health risk. Do you agree?

Estrogen cream and other vaginal estrogens are very effective treatments for atrophic vaginitis, a condition that's common in postmenopausal women and results from a drop in estrogen levels. Estrogen loss can lead to thinning atrophy of the cells lining the vagina and urethra. As a result, women may develop vaginal dryness, itching, and pain with intercourse, as well as a high risk of urinary and vaginal infections.

Estrogens in any form — oral, transdermal, or vaginal — can help restore mucosal cells and alleviate atrophic vaginitis. But applying estrogen directly to the vagina has several advantages. The overall dose can be lower, and circulating blood levels of the hormone aren't raised significantly, so breast and endometrial tissues are less exposed. Circulating estrogen can stimulate the growth of ductal cells in the breast and endometrial cells in the uterus, increasing the risk of breast cancer and endometrial cancer.

In the United States, vaginal estrogen is available in a handful of low-dose preparations, such as estrogen creams Estrace Vaginal Cream and Premarin Vaginal Cream , a tablet Vagifem , and an estrogen-infused vaginal ring Estring.

These preparations are taken daily in gradually increasing amounts until the therapeutic level is reached, and then twice weekly. When low-dose estrogen is applied vaginally, you generally don't need a progestin to offset its potentially carcinogenic effects on the endometrium. So far, it looks as though low-dose vaginal estrogens are safe, at least in the short term. For example, they don't spur any significant growth of endometrial cells when used for up to a year.

The estrogen ring and tablet don't boost blood levels of estrogen significantly. Estrogen levels tend to vary more with estrogen creams because it's difficult to measure out a precise low dose using the applicator provided, which is designed for a higher standard dose see "How to get a low estrogen dose using standard vaginal estrogen creams". The most common side effect of low-dose vaginal estrogen is a clear or milky vaginal discharge.

The vaginal estrogen creams on the market in the United States are designed to deliver estrogen at doses higher than those recommended for the treatment of atrophic vaginitis — that is, 25 micrograms mcg of estradiol or 0.

A standard dose of Estrace vaginal cream contains mcg of estradiol, and a standard dose of Premarin vaginal cream provides 0. Doses this high are sufficient to raise the level of estrogen in the blood, possibly increasing the exposure of other body tissues and spurring the growth of endometrial cells.

You can still use one of these estrogen creams to deliver a low dose of estrogen, but you'll need to take less than the amount indicated on the applicator sold with the creams. Use only as much as you need to be comfortable. This can range from one-half to as little as one-eighth of an applicator of estrogen cream inserted into the vagina daily for the first two to three weeks, then twice a week thereafter.

Even with this regimen, it's difficult to determine how much estrogen is absorbed into the bloodstream. It's probably safe to use low-dose vaginal estrogen twice a week for one year. But after a year of treatment, talk to your clinician about whether your endometrial tissue should be evaluated.

And if you develop any vaginal bleeding, contact your clinician immediately. If you want to skip estrogen altogether, there are non-estrogen moisturizers and lubricants that can help reduce symptoms and ease discomfort during sexual intercourse.

The long-acting moisturizer Replens, placed in the vagina up to three times per week, adheres to the vaginal surface, releases water, and produces a moist film over vaginal tissue. It's also been shown to restore vaginal pH. Water-soluble lubricants, such as Astroglide or K-Y Personal gels and liquids, can be helpful during intercourse.

ABSTRACT: Cancer treatment should address female-specific survivorship issues, including the hypoestrogenic-related adverse effects of cancer therapies or of natural menopause in survivors. Systemic and vaginal estrogen are widely used for symptomatic relief of vasomotor symptoms, sexual dysfunction, and lower urinary tract infections in the general population.

However, given that some types of cancer are hormone sensitive, there are safety concerns about the use of local hormone therapy in women who currently have breast cancer or have a history of breast cancer. Nonhormonal approaches are the first-line choices for managing urogenital symptoms or atrophy-related urinary symptoms experienced by women during or after treatment for breast cancer.

Among women with a history of estrogen-dependent breast cancer who are experiencing urogenital symptoms, vaginal estrogen should be reserved for those patients who are unresponsive to nonhormonal remedies. Additionally, it should be preceded by an informed decision-making and consent process in which the woman has the information and resources to consider the benefits and potential risks of low-dose vaginal estrogen.

Data do not show an increased risk of cancer recurrence among women currently undergoing treatment for breast cancer or those with a personal history of breast cancer who use vaginal estrogen to relieve urogenital symptoms. The American College of Obstetricians and Gynecologists makes the following recommendations and conclusions:. Oncologic care providers are increasingly recognizing that cancer treatment should address female-specific survivorship issues, including the hypoestrogenic-related adverse effects of cancer therapies or of natural menopause in survivors.

Obstetrician—gynecologists and other health care providers frequently face the challenge of understanding and addressing these issues among an increasing cohort of women cancer survivors who experience urogenital symptoms, either from cancer therapy or physiologic menopause.

However, given that some types of cancer are hormone sensitive, there are safety concerns about the use of local hormone therapy in women who currently have breast cancer or have a history of breast cancer 1 , 2.

This document will focus on the use of low-dose vaginal estrogen in women with estrogen-dependent breast cancer. Nonhormonal methods, including moisturizers, lubricants, and topical anesthetics, are first-line approaches for treating urogenital symptoms or atrophy-related urinary symptoms experienced by women during or after treatment for breast cancer 3 , 4. However, for some women, these approaches may have a limited and temporary effect on symptoms and quality of life 5 , 6.

Vaginal estrogen therapy has been shown to provide women with symptomatic relief of urogenital symptoms associated with perimenopause and menopause 3. Generally, vaginal estrogen delivers lower doses of hormone compared with those formulations developed to provide systemic relief of vasomotor symptoms and, thus, offer a different approach to the management of urogenital symptoms among these patients.

There are three main commercially available preparations of vaginal estrogen in the United States: 1 cream, 2 ring, and 3 tablet see Table 1 for suggested regimens. Although there are other forms available, such as compounded vaginal estrogen products, there are concerns regarding the risks of variable composition and potency and the lack of efficacy and safety data [ 7 ].

Vaginal estrogen delivers a low dose of hormone to the local vaginal tissue with minimal systemic absorption. The only vaginal tablet product currently available in the United States contains 10 micro-grams of estradiol hemihydrate.

The second product, the estradiol acetate ring, provides systemic levels of hormone and is not discussed in this document.

Studies show that use of low-dose vaginal estrogens does not result in sustained serum estrogen levels exceeding the normal menopausal range; the lowest rates of systemic absorption are found in the ring and the tablet 8 — When used at the appropriate dose, estradiol creams also deliver a low dose of hormone. Because of the heterogeneity of the estrogens in the formulation, data regarding the use of conjugated equine estrogen cream are less definitive compared with the data for estradiol cream.

In addition, delivery of a set dose of estrogen is more variable with the creams in contrast to the tablet or ring. Thus, data regarding estradiol levels associated with vaginal creams have greater variability compared with tablet or ring formulations. Data do not show an increased risk of cancer recurrence among women currently undergoing treatment for breast cancer or those with a personal history of breast cancer who use vaginal estrogen to relieve urogenital symptoms A nested case—control analysis of a cohort study of women with breast cancer who either did or did not use vaginal estrogen showed no increase of recurrence in vaginal estrogen users In another study, the risk of recurrence in women who used vaginal cream was not increased, irrespective of the total dose prescribed Concerns remain about recurrence risk with use of vaginal estrogen in women with breast cancer who use aromatase inhibitors.

Specifically, the threshold for systemic estrogen levels associated with breast cancer recurrence risk has yet to be determined Some authors note that even a small increase in systemic estradiol levels may have a detrimental effect on recurrence risk and that more data are needed before recommendations can be made regarding the use of vaginal estrogen among this population 16, Studies have demonstrated an initial increase of serum estradiol with the use of low-dose vaginal estrogen estradiol ring or the microgram estradiol tablet among women taking an aromatase inhibitor, though these levels were not sustained over time and increased cancer recurrence was not noted The use of vaginal estrogens may be appropriate for women with urogenital symptoms who use tamoxifen Low and temporary increases of plasma estrogen do not appear to increase recurrence risk in women using tamoxifen because of a competitive interaction with the estrogen receptor Because of these effects, women on aromatase inhibitors who experience urogenital symptoms refractory to nonhormonal approaches may benefit from the short-term use of estrogen with tamoxifen to improve symptoms, followed by a return to normal aromatase inhibitor therapy for the duration of the treatment course When the decision is made to use vaginal estrogen, it should be prescribed at the lowest dose to affect vaginal symptoms and for a limited period until symptoms are improved.
