Everything you need to know about the Kyleena IUD


Kyleena is an intrauterine device (IUD) . It is manufactured by Bayer and is therefore part of the same Navy family as Mirena and Skyla . The Kyleena IUD consists of a soft and flexible polyethylene (plastic) frame in the shape of a T. Kyleena must be inserted and removed by a qualified healthcare professional.

To prevent pregnancy, this IUD slowly releases the progestin levonorgestrel into the uterus over a period of five years. Kyleena is FDA approved for use in women who have given birth or have never given birth.

If you are considering using Kyleena, understanding the facts can help you make a decision with more confidence. It is okay to ask a question about some of the following questions.

The Kyleena IUD helps prevent pregnancy by interfering with sperm. This makes it difficult for sperm to fertilize the egg. So, in essence, Kilina inhibits the movement of sperm.

Kyleena IUDs also contain a progestin – this hormone causes cervical mucus to thicken, the lining of the uterus thins, and sperm survival is reduced. Kyleena can prevent pregnancy in the same way as pills .

The Kyleena IUD contains 19.5 milligrams (mg) of levonorgestrel, which releases 17.5 micrograms (mcg) of this hormone per day. After one year, this number gradually decreases to 9.8 mcg per day and then to 7.4 mcg per day.

Who needs it?

The Kyleena IUD has been specifically investigated in nulliparous women (a fancy medical term for women who have never given birth), so the FDA approved Kyleena for use in women in this population.

The Kyleena product label indicates that this IUD can be used whether you have given birth or not. But IUDs are not recommended for all women, so make sure you meet the criteria to be a good candidate and talk to your doctor about the potential risks.

Post time

You should have a Kyleena IUD inserted during the first seven days of your menstrual cycle or immediately after a first trimester abortion . If Kyleena is given within this time, it will take effect immediately, so you will not need to use any additional contraceptive methods .

If you have a Kyleena IUD inserted at any other time during your monthly cycle, you will need to use a different method of birth control (such as spermicide or condoms ) for the first week after receiving Kyleena. Protection against pregnancy will begin after seven days (one week).

You must wait at least six weeks before having Kyleena inserted after delivery or a second trimester abortion. This allows your uterus to heal completely before the keel is inserted.

Compared to other IUDs

The Kyleena Navy works the same as Mirena and Skyla. There are some differences between these three hormone-releasing IUDs. All three IUDs are very effective birth control methods .

They are inserted into the uterus and can be removed at any time. Your fertility should recover quickly after removing any of these IUDs. So let's compare.

These are the points in favor of Kilina:

  • Kyleena provides continuous pregnancy prevention for up to five years.
  • It is no problem. After pasting, you have nothing else to do.
  • The Kyleena IUD is smaller and has a thinner insertion tube than the Mirena. This can make the insertion process less painful than inserting a Mirena or ParaGuard IUD .
  • Kyleena can be removed at any time during the five-year period.
  • It is completely reversible and your fertility returns quickly; you can get pregnant as soon as Kyleena is removed. About 7 out of 10 women (who want to get pregnant) will become pregnant within 12 months of having Kilina removed .
  • The Kyleena IUD is FDA approved for women who have or have never had children.
  • Kilina may be a good IUD option if you have only had a C-section.
  • Kyleena is a good alternative if you cannot use estrogen-based birth control.
  • If you have a smaller uterus (such as young adolescents and perimenopausal women), Kyleena may be better tolerated than other IUDs.
  • Neither you nor your partner should feel Kilina during sexual intercourse.
  • Kyleena is an ecological contraceptive method.
  • It can be used if you are breastfeeding.


Most women have no problem adjusting to the IUD. However, you may experience some pain, bleeding, or dizziness during and / or after insertion of the Kyleena IUD. If these symptoms persist within 30 minutes of insertion, your Kyleena IUD may not have been inserted correctly.

Be sure to talk to your doctor about any side effects you are experiencing. Some women have severe cramps or back pain for several days or weeks after the Kyleena IUD is inserted.

Side effects

You may have side effects after receiving a Kyleena IUD. In most cases, they disappear after a few weeks or months. The most common side effects of the Kyleena IUD include:

  • Inflammation or infection of the outside of the vagina (vulvovaginitis)
  • Ovarian cysts (diagnosed in about 22% of Kyleena users, usually clear on their own within 1-2 months)
  • Increased bleeding
  • Stomach and / or pelvic pain
  • Acne or seborrhea (oily skin)
  • Headaches or migraines
  • Dysmenorrhea or uterine cramps
  • Chest pain or discomfort

Changes in your period

During the first 3 to 6 months after Kyleena IUD insertion, you may have a greater chance of bleeding and spotting. You may have irregular periods and / or your periods may be heavier or longer than usual.

Although breakthrough bleeding and spotting will most likely decrease in the first three months after administration, your periods may still be irregular.

Over time, your periods are likely to get shorter and easier. Because the progestin in Kyleena thins the lining of the uterus, bleeding may decrease the longer your Kyleena IUD is.

Your periods may stop completely. About 12% of women stop menstruating after using Kyleena for a year.

Risks and complications

Serious complications with Kyleena are very rare. Be sure to tell your doctor right away if you have any problems. Some of the more serious side effects include:

  • Ectopic pregnancy
  • Sepsis (serious, life-threatening infection)
  • Perforation or expulsion

Some of the side effects may be similar to those of other IUDs.


If your Kyleena IUD comes out on its own, chances are you won't even notice it. This is why it is so important to grope for the strings , as it is the only way to know that your Kaileena is still in place.

If your Kyleena IUD has been partially or completely removed, contact your doctor immediately (and use a backup method of birth control). Do not try to remove the remaining part yourself if it is partially released.

Your healthcare provider will most likely perform a pregnancy test (to make sure you are not pregnant) before you have a new Kyleena IUD inserted.

Venereal diseases

The Kyleena IUD does not protect against sexually transmitted diseases (STDs). You are more likely to have pelvic inflammatory disease after contracting Kyleena if you have an STD at the time.

You may be at higher risk if you have multiple sexual partners or a sexual partner who has had multiple sexual partners.


Kyleena has a higher initial cost than other contraceptive methods. The cost of the exam, the Kyleena IUD, insertion, and follow-up visits can range from $ 500 to $ 900.

Medicaid can cover these costs. You can also check your health insurance policy, as Kyleena's coverage must be covered at no additional cost for all non-grandparent insurance plans.


The Kyleena IUD is very effective . This long-acting reversible contraceptive method is more than 99% effective. This means that out of 100 women who use the Kyleena IUD for a year, less than 1 will become pregnant with normal use and ideal use.

With Kyleena's IUD, most pregnancies are due to your Kyleena coming out and you probably didn't realize it happened. Although the chances of pregnancy are very low while using Kyleena, it can happen.

If you become pregnant while the Kyleena IUD is still in place, try to contact your doctor as soon as you realize you are pregnant, as there may be risks associated with this type of pregnancy .


You can remove the Kyleena IUD at any time before the five-year period ends. The Kyleena IUD must be removed after five years. It will not disappear or dissolve in your body. Another Kyleena IUD can be inserted during the same visit.

Never try to remove Kyleena yourself (that's why we have healthcare professionals, after all!). There is a small chance that your Kyleena IUD will come out on its own, but it is more likely that you will need to make an appointment to have it removed.

If you want to switch to a new birth control method (and have continued protection against pregnancy) after you stop taking Kyleena, schedule your IUD removal in the first seven days of your period and start the new method right away.

If Kyleena is removed at any other time during your menstrual cycle, start using the new birth control method at least seven days before Kyleena is removed.

If you had sex without a male condom, female condom, spermicide , or sponge in the five days before Kyleena was removed, you may be at risk of becoming pregnant after IUD removal.
