What’s an IUD?

Mirena is a type of intrauterine system, more commonly known as an IUD. But what is that, exactly?

Mirena is a small T-shaped deviceAn IUD, or intrauterine device, is a small, T-shaped device that is placed into the uterus by a trained healthcare provider during a routine office visit. It provides continuous, highly effective birth control. Keep in mind that no birth control is 100% effective.

Mirena is a hormone-releasing IUD that releases small amounts of a progestin hormone called levonorgestrel locally into the uterus. Mirena lasts for as long as you want, for up to 5 years.

Did you know that a third of OB/GYNs use an IUD for themselves? (Based on a Nov. 2014 survey of 400 female US OB/GYNs aged 25–49 who were using a contraceptive method for pregnancy protection.)

Talk to your OB/GYN to learn more and discuss whether an IUD could be the right choice for you.

Mirena Indications & Usage

Mirena (levonorgestrel-releasing intrauterine system) is a hormone-releasing system placed in your uterus to prevent pregnancy for as long as you want for up to 5 years. Mirena also treats heavy periods in women who choose intrauterine contraception.

Mirena Important Safety Information

Only you and your healthcare provider can decide if Mirena is right for you. Mirena is recommended for women who have had a child.

  • Don't use Mirena if you have a pelvic infection, get infections easily or have certain cancers. Less than 1% of users get a serious infection called pelvic inflammatory disease. If you have persistent pelvic or abdominal pain, see your healthcare provider.
  • Mirena may attach to or go through the wall of the uterus and cause other problems. If Mirena comes out, use back-up birth control and call your healthcare provider.
  • Although uncommon, pregnancy while using Mirena can be life threatening and may result in loss of pregnancy or fertility.
  • Ovarian cysts may occur but usually disappear.
  • Bleeding and spotting may increase in the first 3 to 6 months and remain irregular. Periods over time usually become shorter, lighter or may stop.
    • Mirena does not protect against HIV or STDs.

      Available by prescription only.

      For important risk and use information about Mirena, please see the Full Prescribing Information.

Essure Indication

Essure® is permanent birth control that works with your body to create a natural barrier against pregnancy.

Essure Important Safety Information

Essure is not right for you if you are uncertain about ending your fertility, can have only one insert placed, are or have been pregnant within the past 6 weeks, have had your tubes tied, have an active or recent pelvic infection, or have a known allergy to contrast dye.

Talk to your doctor if you are taking immunosuppressants.

WARNING: You must continue to use another form of birth control until you have your Essure Confirmation Test (3 months after the procedure) and your doctor tells you that you can rely on Essure for birth control. It can take longer than three months for Essure to be effective. Talk to your doctor about which method of birth control you should use during this period. Women using an intrauterine device need to switch to another method. If you rely on Essure for birth control before receiving confirmation from your doctor, you are at risk of getting pregnant.

WARNING: Be sure you are done having children before you undergo the Essure procedure. Essure is a permanent method of birth control.

During the procedure: In clinical trials some women experienced mild to moderate pain (9.3%). Your doctor may be unable to place one or both Essure® inserts correctly. Although uncommon, part of an Essure insert may break off or puncture the fallopian tube requiring surgery to repair the puncture. Your doctor may recommend a local anesthetic. Ask your doctor about the risks associated with this type of anesthesia.

Immediately following the procedure: In clinical trials some women experienced mild to moderate pain (12.9%) and/or cramping (29.6%), vaginal bleeding (6.8%), and pelvic or back discomfort for a few days. Some women experienced nausea and/or vomiting (10.8%) or fainting. In rare instances, an Essure insert may be expelled from the body.

During the Essure Confirmation Test: You will be exposed to very low levels of radiation, as with most x-rays. In rare instances, women may experience spotting and/or infection.

Long-term Risks: There are rare reports of chronic pelvic pain in women who have had Essure. In rare instances, an Essure insert may migrate through the fallopian tubes and may require surgery. No birth control method is 100% effective. Women who have Essure are more likely to have an ectopic pregnancy (pregnancy outside the uterus) if they get pregnant. This can be life-threatening. The Essure insert is made of materials that include a nickel-titanium alloy. Patients who are allergic to nickel may have an allergic reaction to the inserts. Symptoms include rash, itching and hives.

The safety and effectiveness of Essure has not been established in women under 21 or over 45 years old.

Essure does not protect against HIV or other sexually transmitted diseases.

Talk to your doctor about Essure and whether it is right for you.

You can also report any adverse events or product technical complaints involving the Essure system immediately by calling 877-ESSURE1 (877-377-8731).
