Documented Uses

Femring is indicated for the treatment of vasomotor and urogenital symptoms associated with menopause. Use of Femring (estradiol acetate) has been shown to improve symptoms caused by atrophy of the vagina (such as dryness, burning, pruritus and dyspareunia) and/or the lower urinary tract (urinary urgency and dysuria).
Exercise caution with grapefruit products. Grapefruit inhibits CYP3A4 metabolism, which may increase the serum concentration of estradiol acetate.
Exercise caution with St. John's Wort. This herb induces the CYP3A4 metabolism of estradiol acetate. Therefore it may reduce the serum concentration and effectiveness of estradiol acetate.
Estrogen Receptor Agonists [MoA]; Estrogen [EPC]; Estradiol Congeners [CS]
Estradiol, estrone and estriol are excreted in the urine along with glucuronide and sulfate conjugates.
The distribution of exogenous estrogens is similar to that of endogenous estrogens. Estrogens are widely distributed in the body and are generally found in higher concentrations in the sex hormone target organs.
