Estring Vaginal Ring

Estring Vaginal Ring (estradiol) is a prescription-only hormonal therapy used to treat moderate to severe symptoms of vaginal and vulvar atrophy due to menopause. It is designed for postmenopausal women experiencing symptoms such as vaginal dryness, irritation, burning, or painful intercourse caused by decreased estrogen levels.

Estring releases a low, continuous dose of estradiol directly to the vaginal tissues for up to 90 days. This helps relieve vaginal symptoms while limiting how much estrogen enters the bloodstream. It must be prescribed and used under the supervision of a qualified doctor/healthcare provider to ensure safe and appropriate treatment.

According to FDA prescribing information, Estring (estradiol) is indicated for the treatment of moderate to severe symptoms of vaginal and vulvar atrophy due to menopause. This includes symptoms such as:

• Vaginal dryness
• Vaginal itching
• Burning
• Pain during intercourse (dyspareunia)

Estring is intended for local vaginal therapy and is not indicated for systemic menopausal symptoms such as hot flashes.

Estring is a flexible vaginal ring that contains estradiol, a form of estrogen identical to the hormone naturally produced by the body. After menopause, estrogen levels decline, which can lead to thinning, dryness, and irritation of the vaginal tissues (vulvar and vaginal atrophy). Once inserted into the vagina, Estring:

• Releases a low, continuous dose of estradiol directly to the vaginal tissues
• Helps restore and maintain the thickness and elasticity of the vaginal lining
• Increases natural lubrication
• Reduces symptoms such as dryness, itching, burning, and painful intercourse

The ring is designed to remain in place for 90 days, delivering localized estrogen therapy with minimal systemic absorption compared to oral estrogen treatments.

Here are the steps for inserting the Estring Vaginal Ring properly:

• Wash and dry your hands thoroughly.
• Open the package and remove the ring.
• Choose a comfortable position (squatting, lying down, or standing with one leg raised, similar to tampon insertion).
• Hold the ring between your thumb & index finger, press opposite sides together to form a narrow shape.
• Gently push the ring as far into your vagina as possible.
• The exact position is not critical as long as it rests in the upper third of the vaginal vault.
• Once in place, you should not feel discomfort. If you do, gently push it further inside.

Follow these steps for removing the Estring 2 mg ring:

• Wash and dry your hands.
• Insert a finger into the vagina and hook it through the ring.
• Gently pull downward & forward to remove the ring.
• Dispose of the used ring in the trash.
• Insert a new ring immediately if continuing therapy; each ring is worn continuously for 90 days.

This is not a complete list of side effects for Estring Vaginal Ring. If you notice other adverse reactions, tell your doctor right away.

Estrogen therapy, including Estring, is associated with certain risks. Although Estring delivers low-dose local estrogen, the following warnings apply:

• Endometrial Cancer: Unopposed estrogen therapy raises the risk of endometrial cancer. Any unusual vaginal bleeding should be evaluated promptly.
• Cardiovascular Disorders: Estrogen therapy may increase the risk of stroke and deep vein thrombosis (DVT).
• Breast Cancer: Estrogen use may increase the risk of breast cancer.
• Probable Dementia: Estrogen therapy may increase the risk of probable dementia in women 65 years of age or older.
• Estrogens should be used at the lowest effective dose and for the shortest duration consistent with treatment goals and individual risks.

Use caution and clinical monitoring in women with:

• Cardiovascular risk factors (e.g., hypertension, diabetes, tobacco use, obesity)
• Hypertriglyceridemia
• Liver impairment or disease
• Hypothyroidism
• Fluid retention conditions (e.g., cardiac or renal dysfunction)
• History of hormone-dependent tumors
• Endometriosis
• Hypocalcemia
• Exacerbation of asthma, epilepsy, migraine, porphyria, lupus, or hepatic hemangiomas

Monitor for:

• Vaginal irritation, ulceration, erosion, or infection
• Signs of systemic estrogen exposure
• Elevated blood pressure

Patients should have periodic reevaluation to determine the continued need for therapy.

Below is the recommended dosage of Estring for the treatment of moderate to severe symptoms of vulvar and vaginal atrophy due to menopause:

Important Administration:

• The exact position of the vaginal ring inside the vagina is not critical; it should be placed for comfort.
• Most women do not feel the ring once it is properly placed.
• If the ring causes discomfort or is difficult to remove, contact your healthcare provider.

• Leaving the ring in place beyond 90 days is not considered an acute overdose.
• However, the ring may deliver less consistent estradiol after 90 days, which can reduce treatment effectiveness.
• Prolonged retention may increase the risk of vaginal irritation, ulceration, erosion, or infection.

If a ring has been left in place longer than 90 days:

• It should be removed as soon as possible.
• A new ring may be inserted if therapy is to continue.
• Contact a healthcare provider if there is pain, bleeding, discharge, or difficulty removing the ring.

Do not use Estring if you have:

• Undiagnosed abnormal genital bleeding
• Known, suspected, or history of breast cancer
• Known or suspected estrogen-dependent neoplasia
• Active or history of (DVT) deep vein thrombosis or pulmonary embolism
• Active or recent arterial thromboembolic disease (e.g., stroke, myocardial infarction)
• Known liver dysfunction or disease
• Known protein S, protein C, or antithrombin deficiency, or other known thrombophilic disorders
• Known hypersensitivity to estradiol or any components of Estring
• Pregnancy (Estring is not indicated for use during pregnancy)

• Store at 20°C-25°C (68°F-77°F).
• Excursions permitted between 15°C-30°C (59°F-86°F).
• Keep the ring in its original sealed pouch until ready for use.
• Protect from excessive heat.
• Do not refrigerate or freeze Estring Vaginal Ring.
• Do not use after the expiration date printed on the Estring package.
• Keep out of reach of children and pets.

Disposal Instructions

• After removal, place the used ring in the original pouch (if available) or wrap securely.
• Dispose of it in the household trash.
• Do not flush Estring down the toilet.

Estring provides low systemic absorption, and estradiol is metabolized via CYP3A4. Drug interactions similar to systemic estrogens are possible but may be less clinically significant due to lower circulating estrogen levels.

If Estring is unsuitable, not tolerated, or does not adequately relieve symptoms, your healthcare provider may recommend alternative local vaginal estrogen therapies. Always consult your healthcare provider before switching therapies.
