What is the most important information I should know about ESTRING (an estrogen hormone)?
- Estrogens increase the chance of getting cancer of the uterus.
Report any unusual vaginal bleeding right away while you are using ESTRING. Vaginal bleeding after menopause may be a warning sign of cancer of the uterine (womb). Your healthcare provider should check any unusual vaginal bleeding to find out the cause.
- Do not use estrogens with or without progestins to prevent heart disease, heart attacks, strokes, or dementia.
Using estrogens with or without progestins may increase your chance of getting heart attacks, strokes, breast cancer, and blood clots. Using estrogens with or without progestins may increase your risk of dementia, based on a study of women age 65 years or older.
You and your healthcare provider should talk regularly about whether you still need treatment with ESTRING.
ESTRING® (estradiol vaginal ring) is a slightly opaque ring with a whitish core containing a drug reservoir of 2 mg estradiol. Estradiol, silicone polymers and barium sulfate are combined to form the ring. When placed in the vagina, ESTRING releases estradiol, approximately 7.5 mcg per 24 hours, in a consistent stable manner over 90 days. ESTRING has the following dimensions: outer diameter 55 mm; cross-sectional diameter 9 mm; core diameter 2 mm. One ESTRING should be inserted into the upper third of the vaginal vault, to be worn continuously for three months.
ESTRING (estradiol vaginal ring) is an estrogen indicated for the treatment of moderate to severe urogenital symptoms due to postmenopausal atrophy of the vagina (such as dryness, burning, pruritus and dyspareunia) and/or the lower urinary tract (urinary urgency and dysuria).

Published Studies Related to Estring (Estradiol Vaginal Ring)
Polycystic ovary syndrome and cardiovascular risk in young patients treated with drospirenone-ethinylestradiol or contraceptive vaginal ring. A prospective, randomized, pilot study. [2010.09]
OBJECTIVE: To compare the effects of a pill containing drospirenone with those of a combined contraceptive vaginal ring on the lipid and carbohydrate metabolism and on the surrogate markers of arterial function...
Effects of oral and transvaginal ethinyl estradiol on hemostatic factors and hepatic proteins in a randomized, crossover study. [2007.06]
CONTEXT: The use of combined hormonal contraceptives with ethinyl estradiol (EE) and a progestin results in alterations in potential biomarkers of venous thromboembolism risk. Evaluation of the impact of delivery route on these changes is difficult due to an interaction between EE and the progestin component. OBJECTIVE: The aim of the study was to compare the impact of oral and vaginal administration of EE alone on hemostatic variables and estrogen-sensitive liver proteins... CONCLUSION: Our results provide evidence that the customary effects of combined hormonal contraceptives on hemostatic variables and estrogen-sensitive liver proteins are largely related to EE and independent of delivery route during short-term treatment.
Efficacy, acceptability and tolerability of the combined contraceptive ring, NuvaRing, compared with an oral contraceptive containing 30 microg of ethinyl estradiol and 3 mg of drospirenone. [2006.12]
CONCLUSION: NuvaRing has comparable efficacy and tolerability to a COC containing 30 microg of EE and 3 mg drospirenone. User acceptability of both methods was high.
Effects on cycle control and bodyweight of the combined contraceptive ring, NuvaRing, versus an oral contraceptive containing 30 microg ethinyl estradiol and 3 mg drospirenone. [2006.09]
BACKGROUND: The objective of this study was to compare cycle control, cycle-related characteristics and bodyweight effects of NuvaRing with those of a combined oral contraceptive (COC) containing 30 microg of ethinyl estradiol and 3 mg of drospirenone... CONCLUSION: NuvaRing was associated with better cycle control than the COC, and there was no clinically relevant difference between the two groups in bodyweight.
Comparative effects of a contraceptive vaginal ring delivering a nonandrogenic progestin and continuous ethinyl estradiol and a combined oral contraceptive containing levonorgestrel on hemostasis variables. [2006.07]
OBJECTIVE: This study aimed to compare the effects on hemostasis variables of a contraceptive vaginal ring with those of an oral contraceptive... CONCLUSION: The contraceptive vaginal ring affected some measured hemostasis variables and sex hormone-binding globulin differently from the oral contraceptive, most likely because of difference in androgenicity of the progestins. The results suggest that the contraindications for oral contraceptive use would also apply to the tested contraceptive vaginal ring.
