Reduces Heavy Periods

Mirena is the first and only birth control that's FDA-approved to treat heavy periods in women who choose intrauterine birth control.

How it helps

After Mirena Placement

Now that you’ve had Mirena placed, you may notice some changes to your period. Here’s some information about what you may be able to expect.

As your body adjusts to Mirena

When you start Mirena, it’s important to pay close attention to your body and the changes it may go through.

While your body is adjusting, you may notice the following:

In the first 3 to 6 months,

Your period may be irregular

Your period may be heavier at first and the number of bleeding days may increase

You may have frequent spotting or light bleeding

A few women may find that their periods are heavier than normal. Call your healthcare provider if your period continues to be heavier than usual.

After your body has adjusted,

Your period may be shorter and lighter than before

Your period may remain irregular

Your period may stop altogether

These effects may continue for as long as you have Mirena. However, your period is likely to return once Mirena is removed. If you haven’t gotten your period for 6 weeks or more during Mirena use, or you feel like you may be pregnant, call your healthcare provider to rule out pregnancy.

Uterine Lining Chart

With Mirena, monthly thickening of the uterine lining is lessened, which means bleeding is reduced.

For women with heavy periods,
bleeding may be reduced

In a clinical trial of Mirena in women with heavy periods, the majority had an 80% reduction in bleeding as early as 3 months and a 90% reduction at 6 months.

Checking your threads

With Mirena (levonorgestrel-releasing intrauterine system), there’s no daily routine. However, you will need to do a self-check of the threads of your Mirena once a month to make sure it’s where it’s supposed to be. Ask your healthcare provider to explain how.

The threads attached to Mirena are the only part you should feel when it is in your uterus. If you feel more than just the threads, Mirena is not in the right position and may not prevent pregnancy.

If you have trouble finding the threads or feel more than just the threads, call your healthcare provider right away. And in the meantime, use a non-hormonal form of birth control as a back-up.

No birth control is right for everyone and there are risks associated with Mirena that you should know about. For detailed information about possible side effects, some potentially serious, please see Mirena Safety Considerations and the Patient Information.

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.

Skyla Indication

Skyla (levonorgestrel-releasing intrauterine system) is a hormone-releasing IUD that prevents pregnancy for up to 3 years.

Skyla Important Safety Information

  • If you have a pelvic infection, get infections easily, or have certain cancers, don't use Skyla. Less than 1% of users get a serious pelvic infection called PID.
  • If you have persistent pelvic or stomach pain or if Skyla comes out, tell your doctor. If Skyla comes out, use back-up birth control. Skyla may attach to or go through the uterus and cause other problems.
  • Pregnancy while using Skyla is uncommon but 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.

Skyla does not protect against HIV or STDs.

Only you and your healthcare provider can decide if Skyla is right for you. Skyla is available by prescription only.

For important risk and use information about Skyla, 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).
