Estring releases estrogen that is absorbed directly through the skin of the vaginal wall. Estring is used after menopause to treat moderate to severe menopausal changes in and around the vaginal area such as as dryness, burning, and itching of the vaginal area, urgency or irritation with urination, and pain during sexual intercourse). Estring is an off-white, soft, flexible ring with a center that contains 2 mg of Estradiol. The ring releases Estradiol into the vagina in a consistent, stable manner for 90 days. It should be removed after 90 days of continuous use. If continued Therapy is required, the ring should be replaced. Learn more
