Estring Vaginal Ring at CanadaPharmacyOnline.com

Brand Estring Vaginal Ring, manufactured by Pfizer, is available in many countries worldwide, including Canada, the United Kingdom, and the European Union.

Generic estradiol is currently unavailable (at this pharmacy).

Dosage:

Estring is a vaginal ring that contains 2 mg of estradiol, a form of estrogen. It gradually releases a low dose of estradiol (approximately 7.5 mcg per 24 hours) directly into the vagina.

Your doctor will determine the appropriate dosage based on the individual needs and medical conditions.

Usage:

Estring Vaginal Ring (estradiol) is a prescription medication used to treat menopause symptoms. Menopause is defined as 12 consecutive months without a menstrual period, marking the end of menstrual cycles. It results from a natural decline in reproductive hormones, typically occurring in women as they reach their 40s or 50s. Estring Vaginal Ring addresses symptoms of menopause such as moderate to severe atrophic vaginitis (vaginal dryness, itching, and burning) and dyspareunia (painful intercourse) due to menopause.

Mechanism of Action:
Estring Vaginal Ring (estradiol) is a form of estrogen, a female hormone. It releases a continuous, low dose of estradiol directly into the vagina. This helps to restore the vaginal tissues that have become thin, dry, and fragile due to a decrease in natural estrogen levels during menopause. By replenishing estrogen in the vaginal area, it helps to improve elasticity, lubrication, and overall vaginal health.

Use Estring Vaginal Ring exactly as your doctor prescribes, following the instructions in the Patient Information Leaflet. Consult your doctor for personalized guidance and safe use.
