DOSAGE AND ADMINISTRATION
One ESTRING (estradiol vaginal ring) is to be inserted as deeply as possible into the upper one-third of the vaginal vault. The ring is to remain in place continuously for three months, after which it is to be removed and, if appropriate, replaced by a new ring. The need to continue treatment should be assessed at 3 or 6 month intervals.
Should the ring be removed or fall out at any time during the 90-day treatment period, the ring should be rinsed in lukewarm water and re-inserted by the patient, or, if necessary, by a physician or nurse.
Retention of the ring for greater than 90 days does not represent overdosage but will result in progressively greater underdosage with the attendant risk of loss of efficacy and increasing risk of vaginal infections and/or erosions.
Instructions for Use

The ring should be pressed into an oval and inserted into the upper third of the vaginal vault. The exact position is not critical.

Gently push ESTRING (estradiol vaginal ring) further into the vagina.
ESTRING (estradiol vaginal ring) use

If ESTRING (estradiol vaginal ring) is expelled totally from the vagina, it should be rinsed in lukewarm water and reinserted by the patient (or doctor/nurse if necessary).
