Femring

What is Femring?

Femring is a prescription vaginal ring that contains estradiol (an estrogen hormone). Femring should be removed after 90 days of continuous use. If you and your healthcare provider decide you should continue using Femring, a new ring can be inserted in your vagina.

What is Femring used for?

Femring is used after menopause to:

• reduce moderate to severe hot flushes

Estrogens are hormones made by a woman’s ovaries. The ovaries normally stop making estrogens when a woman is between 45 and 55 years old. This drop in body estrogen levels causes the “change of life” or menopause, the end of monthly menstrual periods. Sometimes both ovaries are removed during an operation before natural menopause takes place. The sudden drop in estrogen levels causes “surgical menopause”.
When estrogen levels begin dropping, some women get very uncomfortable symptoms, such as feelings of warmth in the face, neck, and chest, or sudden intense episodes of heat and sweating (“hot flashes” or “hot flushes”). In some women the symptoms are mild, and they will not need to take estrogens. In other women, symptoms can be more severe.

• treat moderate to severe menopausal changes in and around the vagina

You and your healthcare provider should talk regularly about whether you still need treatment with Femring to control these problems. If you use Femring only to treat your menopausal changes in and around your vagina, talk with your healthcare provider about whether a topical vaginal product would be better for you.
