Formula Information

A small arrow pointing down

Estriol 0.625 mg Vaginal Suppositories are a specialized formulation designed to deliver a low dose of the estrogen hormone estriol directly to the vaginal tissue. Estriol is a naturally occurring estrogen that is often used in hormone replacement therapy, particularly for menopausal symptoms. The suppository form is advantageous for those who may have difficulties with oral administration or for whom localized treatment is preferred. This solid dosage form is inserted into the vagina, where it dissolves or melts, allowing the estriol to be absorbed by the local tissue and exert its therapeutic effects.

The primary use of Estriol Vaginal Suppositories is to alleviate symptoms associated with atrophic vaginitis, a condition commonly experienced by postmenopausal women due to decreased estrogen levels. Symptoms can include vaginal dryness, itching, irritation, and painful intercourse. By delivering estriol directly to the affected area, these suppositories help to restore the vaginal tissue, improve lubrication, and reduce discomfort. Additionally, this localized approach minimizes systemic absorption, which can be beneficial for patients who need to limit their overall exposure to estrogens.

Estriol may also play a role in the management of other genitourinary symptoms such as urinary urgency and recurrent urinary tract infections, by improving the health of the urogenital epithelium. While the primary action is local, some systemic absorption of estriol does occur, which may contribute to the overall therapeutic effects. It is important for prescribers to consider the patient's individual hormonal profile and risk factors when recommending this therapy, as estrogen products can be contraindicated in certain conditions such as estrogen-dependent neoplasms or a history of thromboembolic disorders.

Patients should be instructed on the proper insertion technique for vaginal suppositories to ensure optimal efficacy and comfort. It is also important to discuss the timing of administration and how to manage missed doses. As with any estrogen therapy, patients should be monitored for adverse effects, and the lowest effective dose should be used for the shortest duration necessary to manage symptoms.

For prescribers and patients considering the use of Estriol 0.625 mg Vaginal Suppositories, our team at Bayview Pharmacy is available to provide additional information and guidance. We can assist with individualized dosing recommendations, potential drug interactions, and answer any questions regarding the formulation and its use. If you have any questions or need further assistance, please do not hesitate to reach out to us.

Drug Interactions

A small arrow pointing down

Estriol is a form of estrogen, a female hormone that regulates various processes in the body. Estriol 0.625 mg vaginal suppositories are designed to be inserted into the vagina where they dissolve and release the hormone directly at the site of action. This local administration can help minimize systemic absorption and reduce the potential for systemic side effects. Estriol is commonly used to treat symptoms of menopause such as vaginal dryness, itching, and burning. It can also be used in the management of atrophic vaginitis and kraurosis vulvae.

When considering the use of estriol vaginal suppositories, it is important to be aware of potential drug interactions. Estriol can interact with other medications, herbs, or supplements the patient may be taking. For example, the concurrent use of estriol with other estrogen products, including oral contraceptives or hormone replacement therapy, may increase the overall estrogenic effects and the risk of side effects such as endometrial hyperplasia or thromboembolic events. Patients should inform their healthcare provider of all medications they are taking, including over-the-counter drugs and herbal supplements.

Enzyme inducers such as carbamazepine, phenytoin, barbiturates, rifampicin, and St. John's Wort may reduce the plasma concentrations of estrogens, potentially leading to a decrease in the therapeutic effects of estriol suppositories. Conversely, enzyme inhibitors like erythromycin, ketoconazole, and grapefruit juice may increase plasma concentrations of estrogens, potentially increasing the risk of side effects.

Patients with a history of hormone-sensitive cancers or thromboembolic disorders should use estriol with caution, as estrogen may increase the risk of recurrence or exacerbation of these conditions. Additionally, estriol may alter the effectiveness of anticoagulant medications, such as warfarin, requiring close monitoring of coagulation parameters and possible dose adjustments.

It is also important to consider the impact of estriol on laboratory tests. Estrogens can affect thyroid function tests, coagulation factors, lipid profiles, and glucose tolerance tests. Healthcare providers should interpret lab results with consideration of estrogen therapy and may require more frequent monitoring.

Patients should be advised to report any unusual vaginal bleeding, new breast lumps, or signs of thromboembolic events such as sudden chest pain or shortness of breath to their healthcare provider. Additionally, patients should be counseled on the proper administration of vaginal suppositories to ensure optimal efficacy and safety.

If you have any questions or require further information regarding the use of Estriol 0.625 mg vaginal suppositories, including potential drug interactions and their management, please do not hesitate to reach out to us at Bayview Pharmacy. Our team of compounding pharmacists is dedicated to providing comprehensive support to both patients and prescribers to ensure safe and effective treatment outcomes.

How Does it Work

A small arrow pointing down

Estriol 0.625 mg Vaginal Suppositories are a specialized form of medication designed to deliver estriol, a naturally occurring estrogen, directly to the vaginal tissue. When inserted into the vagina, the suppository begins to dissolve or melt due to the warmth and moisture present in the vaginal environment. As the suppository base dissolves, it releases the active ingredient, estriol, which is then absorbed through the vaginal mucosa.

The absorption of estriol into the vaginal tissue provides a localized effect, which is particularly beneficial for treating conditions such as atrophic vaginitis, a condition characterized by thinning and inflammation of the vaginal walls due to a decrease in estrogen levels. This condition is common in postmenopausal women. By delivering estriol directly to the affected area, the suppository helps to replenish estrogen levels, promoting the regeneration of vaginal tissue, improving lubrication, and alleviating symptoms such as dryness, itching, and discomfort during intercourse.

In addition to its local effects, a small amount of estriol may be absorbed systemically, but the primary intention of this dosage form is to exert its action at the site of application. This targeted approach allows for a lower dose of estrogen to be used, potentially reducing the risk of systemic side effects and complications associated with higher levels of estrogen. It is important to note that while estriol vaginal suppositories can provide relief from the symptoms of atrophic vaginitis, they may not be suitable for all patients, such as those with a history of estrogen-sensitive cancers or those who are pregnant or breastfeeding.

For prescribers considering this formulation for their patients, it is crucial to evaluate the patient's medical history, current medications, and overall health status to ensure that estriol vaginal suppositories are an appropriate treatment option. Patients should be instructed on the correct method of insertion and the importance of adhering to the prescribed dosing schedule to achieve the best therapeutic outcomes. Regular follow-up appointments are recommended to monitor the patient's response to treatment and to make any necessary adjustments to the therapy.

Other Uses

A small arrow pointing down

While the primary indication for Estriol 0.625 mg vaginal suppositories is to provide local relief from menopausal symptoms such as vaginal atrophy, dryness, itching, and burning, this formulation may also serve other therapeutic roles. For instance, it has been observed that estriol has a role in maintaining the health of the lower urinary tract. Thus, the use of these suppositories might benefit women experiencing urinary incontinence or recurring urinary tract infections, as estriol can help in restoring the urogenital system's normal flora and mucosal thickness.

Moreover, some studies suggest that estriol might have fewer systemic estrogenic effects compared to other forms of estrogen, which could potentially make it a preferred choice for patients looking for localized hormone therapy with minimal systemic impact. However, it is worth noting that the systemic absorption through vaginal administration is still possible, and its extent can vary between individuals. Therefore, while estriol has been chosen for its gentler profile and predominantly local effects, patients requiring strictly localized therapy should be monitored accordingly.

Another potential off-label use for estriol vaginal suppositories could involve their role in improving the symptoms associated with genitourinary syndrome of menopause (GSM), which includes not only vaginal but also sexual symptoms, such as dyspareunia. The hormonal support provided by estriol can improve lubrication and elasticity, which can lead to enhanced comfort during sexual activity and an improvement in sexual health overall. However, as with any off-label use, it's important to consider the balance of benefits to risks and to discuss these with a healthcare provider.

Lastly, some emerging research has explored the possibility of using estriol in the context of skin rejuvenation, given its role in collagen synthesis. While this is not a common use for vaginal suppositories, and more research is necessary to establish efficacy and safety in this context, there could be potential for topical estriol formulations in aesthetic medicine.

Beyond the scope of menopausal symptom relief, it is clear that Estriol 0.625 mg vaginal suppositories could have a range of applications. However, any additional uses should be well-supported by clinical evidence and undertaken with medical guidance. If you have any questions regarding the potential uses of this formulation or if it may be right for your needs, please do not hesitate to reach out to us at Bayview Pharmacy for further information and professional advice tailored to your specific case.
