Estring (Estradiol) Vaginal Ring From Canada

What is Estring?

Estring (Estradiol) is a flexible vaginal ring that contains a low dose of estrogen. It is used to treat symptoms of postmenopausal urogenital atrophy, such as vaginal dryness, burning, and discomfort during intercourse. Estring is designed to provide localized estrogen therapy over three months, helping to alleviate symptoms caused by estrogen deficiency.

How Estring Works

Estring delivers a small, consistent dose of estradiol directly to the vaginal tissues, which helps restore the natural estrogen balance in postmenopausal women. By increasing local estrogen levels, Estring improves the thickness and elasticity of the vaginal and urethral tissues, reducing dryness, itching, and irritation. It also helps with other urogenital symptoms like painful intercourse and urinary urgency.

Estring Dosage and Administration

Each Estring ring contains 2 mg of estradiol, which is slowly released at a rate of 7.5 µg per day. The ring is inserted into the vagina and left in place for 90 days. After 90 days, the ring should be removed and, if necessary, replaced with a new ring. It is important to follow your healthcare provider’s instructions for proper use and to ensure regular follow-ups to assess your treatment.

If the ring falls out, it can be rinsed with lukewarm water and reinserted. Estring should be used as prescribed, and patients should avoid using other vaginal products without their healthcare provider’s approval.

Possible Side Effects of Estring

Common side effects of Estring include:

• Vaginal discomfort or irritation
• Vaginal discharge
• Headache
• Upper respiratory tract infection
• Back pain

Serious side effects are rare but may include:

• Blood clots
• Stroke
• Breast or uterine cancer
• Severe allergic reactions

Contact your healthcare provider immediately if you experience unusual vaginal bleeding, signs of blood clots, or any severe reactions. Regular monitoring is recommended during treatment with Estring.

Drug Interactions

Estring may interact with other medications, including anticoagulants, antihypertensives, and certain herbal supplements. Always inform your healthcare provider about all the medications and supplements you are taking to avoid potential interactions. Estring may also interact with other forms of estrogen therapy or hormone replacement therapy.

Precautions When Using Estring

Before using Estring, inform your healthcare provider if you have a history of:

• Breast or uterine cancer
• Blood clot disorders
• Heart disease or stroke
• Undiagnosed vaginal bleeding

Estring should not be used during pregnancy or while breastfeeding. Additionally, Estring may not be suitable for women with certain vaginal conditions, such as vaginal stenosis or severe prolapse, which may prevent the ring from staying in place.

Buying Estring from Canada

Purchasing Estring from Canada can be a cost-effective solution for U.S. patients, as prescription medications are often more affordable in Canada. To buy Estring from a Canadian pharmacy, you will need a valid prescription from your U.S. healthcare provider. Ensure that you purchase from a licensed Canadian pharmacy to avoid counterfeit medications.

Storage Instructions for Estring

Store Estring at room temperature (15°C to 30°C) in its original packaging to protect it from moisture and light. Keep it out of reach of children and pets. Do not use Estring after its expiration date.
