What is it?
  • The hormonal IUD (intrauterine device) is a small, flexible T-shaped plastic device that’s placed inside your uterus to prevent pregnancy.

  • There are thin strings attached to the tip of the IUD, which hang a little bit out of the cervix. 

  • You can only feel the IUD if you place your finger deep into your vagina. Your partner can’t feel the strings.

  • A health care provider inserts the IUD into your uterus during a pelvic exam.

  • The hormonal IUD is one of the most effective birth control methods available — it’s 99% effective in preventing pregnancy1,  and it works for up to 3 to 7 years.

  • The hormonal IUD is low maintenance. There’s no chance of forgetting to take it or using it incorrectly.

  • If you decide you want to get pregnant, a health care provider can remove the IUD and you can try to get pregnant right away.

  • Hormonal IUD brands include Mirena, Skyla, Kyleena, and Liletta.
  • The hormonal IUD releases the hormone progestin to stop you from getting pregnant. 

  • The progestin works by:

    • Stopping your ovaries from releasing eggs. When eggs aren’t released, you can’t get pregnant.

    • Making the mucus in your cervix too thick for sperm to pass through. This prevents sperm from meeting an egg.
  • You can get a hormonal IUD at your medical facility. 
  • In the United States, a hormonal IUD can cost up to $1,300. The cost may vary depending on where you live.

  • Kaiser Permanente members may be able to get a hormonal IUD at low or no cost.2  
  • The hormonal IUD must be inserted by a health care provider.

  • The one-time procedure only takes a few minutes.

  • The provider puts a speculum into your vagina and uses a special tool to insert the IUD through the opening of your cervix and into your uterus.

  • Once it’s inserted, there’s no daily maintenance. It lasts up to 3 to 7 years.

  • You’ll need to get the IUD removed by a provider after 3 to 7 years, when it expires.
  • The hormonal IUD is safe and 99% effective in preventing pregnancy.

  • It’s a long-term birth control method, lasting up to 3 to 7 years.

  • There’s no daily or regular maintenance, and you don’t need to go to the pharmacy for refills. It works until it expires or you have it taken out.

  • It can be used immediately after you have a baby and while you’re breastfeeding.

  • The hormonal IUD won’t affect your fertility.3 You can try to get pregnant once you take it out.

  • Periods may be lighter, less painful, or absent completely.

  • It may help cut down on period cramps.
  • The hormonal IUD doesn’t protect against sexually transmitted infections (STIs/STDs), including HIV. Even if you have an IUD, you should use a condom every time you have sex to reduce your chances of getting or spreading STIs.

  • Many people experience cramps or backaches during the IUD insertion and for a few days after the procedure.  

  • You may have extra spotting, or light vaginal bleeding, between periods for the first few months.

  • Serious complications and side effects are rare. Rare complications may include: The IUD can poke through the wall of the uterus, the IUD can fall out of the uterus, or you can get an infection.
  • You can have the hormonal IUD taken out whenever you want. You must get it taken out after 3 to 7 years, when the hormonal IUD expires.

  • A provider must do the IUD removal.

  • Hormonal IUD removal is a quick procedure. The provider gently pulls on the strings, and the IUD slips out easily with minimal or no discomfort.
