Estring Information

Estring is a vaginal ring. It is made of three key things: estraodial, barium sulfate and silicone polymers. Also called estradiol vaginal ring, Estring is inserted in the vagina. While there, it releases 7.5mcg of estradiol in 24 hours. Estradiol is a form of estrogen, which is a female sex hormone.  The ring is used to treat orogental signs of post-menopausal atrophy of the vagina. These include vagina dryness, itching, dysparenia and burning. This can also cause lower urinary tract issues like dysuria or urinary urgency.

How To Use

Asingle estradiol vaginal ring should be inserted into the vagina. Press it between two fingers and press it into an oval shape. Insert it deeply or into the upper one third of your vagina. Once in place you should not feel it or feel a sense of discomfort. If you do, push it further. Leave it inside for 90 days. After that, get a new Estring. In case you forget to remove after 90days, it will lose its efficacy and trigger vaginal infections or vaginal erosion. If for some reason it comes out before 3 months, clean it in lukewarm water and insert it gently once again. You might as well have a nurse put it in.
