ESTRING is a type of hormone replacement therapy primarily used to manage certain symptoms associated with menopause, such as vaginal dryness, itching, and burning. It is a vaginal ring that releases a steady, low dose of estradiol, a form of estrogen, directly into the vaginal tissue. By doing so, ESTRING helps to replenish the diminished estrogen levels in postmenopausal women, providing relief from the uncomfortable vaginal symptoms. The ring is typically inserted into the vagina and left in place for three months before needing to be replaced. ESTRING is designed for ease of use and aims to provide localized treatment with minimal systemic absorption, making it a preferred option for women seeking targeted relief from menopausal vaginal symptoms.
