  • What is the most important information I should know about Femring?

    Using estrogen alone increases your chance of getting cancer of the uterus (womb). Report any unusual vaginal bleeding right away while you are using Femring. Vaginal bleeding after menopause may be a warning sign of cancer of the uterus (womb). Your healthcare provider should check any unusual vaginal bleeding to find out the cause.

    Do not use Femring if you have unusual vaginal bleeding, currently have or have had certain cancers, had a stroke or heart attack, currently have or had blood clots or liver problems, think you may be pregnant, or are allergic to any of the ingredients in Femring.

  • What should I tell my doctor before I take the first dose of Femring?

    Tell your doctor about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Femring. Also, talk to your doctor about your complete medical history, especially if you have any unusual vaginal bleeding; asthma (wheezing); epilepsy (seizures); diabetes; migraine; endometriosis; lupus; problems with your heart, liver, thyroid, kidneys; or if you have high calcium levels in your blood.

    Tell your doctor if you are going to have surgery or will be on bedrest or if you are breastfeeding.

  • What is the usual dosage?

    The information below is based on the dosage guidelines your doctor uses. Depending on your condition and medical history, your doctor may prescribe a different regimen. Do not change the dosage or stop taking your medication without your doctor's approval.

    Adults: There are two doses of Femring available: 0.05 milligrams (mg) a day and 0.10 mg a day. Each ring should remain in the vagina for 3 months. You should be started at the lowest dose.

  • How should I take Femring?

    Femring is inserted into your vagina by you or your healthcare provider. Femring should stay in your vagina for 3 months. After 3 months, the Femring should be removed and a new Femring inserted.

    To insert Femring into your vagina, wash and dry your hands and remove Femring from its pouch. Choose the position that is most comfortable for you (for example, lying down or standing with one leg up).

    Use your thumb and index finger to press the sides of the ring together so it is in a figure-eight shape. Use your other hand and hold open the folds of skin around your vagina.

    Place the tip of the ring in the vaginal opening and then use your index finger to push the folded ring gently into your vagina. Push it toward your lower back as far as you can. If the ring feels uncomfortable, you probably did not push it into your vagina far enough. There is no danger of Femring being pushed too far up in the vagina or getting lost. The exact position of Femring in the vagina is not important for it to work.

    If your Femring comes out of your vagina before 3 months, clean it with warm water and put it back in your vagina. If Femring comes out often, tell your healthcare provider. Femring may not be right for you.

    You may leave Femring in place if you need to use medicine for a vaginal infection. You may leave Femring in place during intercourse. If you take Femring out during intercourse or it comes out, clean it with warm water and put it back in your vagina.

    If you lose your Femring, a new Femring should be put in place for 3 months.
