One Application—90 Days of Treatment
ESTRING is an off-white, soft, flexible ring with a core that contains 2 mg of estradiol (an estrogen hormone).
Each ESTRING ring lasts for 90 days. After that, there won’t be enough estradiol left to provide you with relief, so the ring should be taken out.
Keep in mind that estrogens such as ESTRING should be used only as long as needed. You and your healthcare professional should talk regularly (for example, every 3 to 6 months) about whether you still need treatment with ESTRING.
How Long ESTRING Takes to Work
After you start using ESTRING, be patient. It may take about 2 to 3 weeks to restore the tissue of the vagina and urinary tract to a healthier condition. It can also take that long to feel the full effect of ESTRING in relieving your symptoms. If your symptoms persist for more than a few weeks after beginning ESTRING therapy, contact your doctor or healthcare professional.
